# DELEGATION SPECIFICATION: HARNESS-DRIVEN VALIDATION LOOP
|
||||
slug: sketch-focus-arbiter · repo: /home/tommaso/projects/apps/orca_cad · branch: cad-mainline
|
||||
|
||||
## 1. TARGET GOAL
|
||||
|
||||
**Functional Objective.** Keyboard input in the Design tab is routed by WHAT THE KEY IS, not by
|
||||
which widget the window manager decided to focus. Adopted from FreeCAD's
|
||||
`DrawSketchKeyboardManager::detectKeyboardEventHandlingMode`
|
||||
(src/Mod/Sketcher/Gui/DrawSketchKeyboardManager.cpp), which never queries focus at all:
|
||||
|
||||
- digit, `-`, `.`, `,` -> the open value field
|
||||
- Backspace / Delete -> the open value field (when one is open)
|
||||
- Enter / Return / Tab -> commit the field, control returns to the view
|
||||
- a letter -> the sketch-tool shortcut map, as today
|
||||
- Esc -> the existing CadLevel LIFO (DesignInteraction.hpp), unchanged
|
||||
- anything else -> sticky: whoever had it keeps it
|
||||
|
||||
Observable postcondition: for EVERY sketch tool that opens a value field, a value typed
|
||||
immediately after the field appears — with NO click into the field — is the value committed.
|
||||
Today the prefill is committed instead whenever the WM withholds focus.
|
||||
|
||||
**Target Files / Scope (writable).**
|
||||
src/slic3r/GUI/CAD/DesignPanel.cpp (the arbiter lives in the existing wxEVT_CHAR_HOOK)
|
||||
src/slic3r/GUI/CAD/DesignCanvas.cpp/.hpp (forwarding entry points only)
|
||||
src/slic3r/GUI/CAD/SketchInlineEditor.cpp/.hpp (accept a programmatically delivered character)
|
||||
scripts/CAD/check-gui-click-edit.py (F2P oracle — authoring exception, see §4)
|
||||
Everything else read-only. No dependency additions, no reformatting.
|
||||
|
||||
**Open Bindings.**
|
||||
- The in-canvas ImGui field on wip/in-canvas-value-field is NOT in scope. Default: the arbiter
|
||||
is implemented against the CURRENT wxFrame field on cad-mainline, because content-based
|
||||
routing makes the window's focus irrelevant either way. If it later moves in-canvas the
|
||||
arbiter is unchanged.
|
||||
- Tools whose field is opened by a toolbar button rather than a gesture (Constrain path) are
|
||||
covered by the same arbiter but are not in the F2P tool list. Default: assert them in P2P only.
|
||||
|
||||
## 2. HARNESS ENVIRONMENT & GROUND TRUTH
|
||||
|
||||
The rig container `orcacad-gui` on nativedev IS the harness. Xvfb `:11` + openbox, the app under
|
||||
test, `xdotool` for synthetic input, and an MCP socket at `/tmp/mcp.sock` that reports sketch
|
||||
state as JSON. It is a closed loop: drive input, read geometry back, assert. No window manager
|
||||
politics, no human.
|
||||
|
||||
Harness interface (ordered; each slot one invocation, one exit code):
|
||||
S1 sync docker cp <file> orcacad-gui:/OrcaSlicer/<path>
|
||||
S2 build docker exec orcacad-gui ninja -C /OrcaSlicer/build orca-slicer
|
||||
S3 restart docker exec orcacad-gui /OrcaSlicer/scripts/CAD/start-headless-gui.sh
|
||||
S4 F2P docker exec -e DISPLAY=:11 orcacad-gui python3 /tmp/check-gui-click-edit.py --attach
|
||||
S5 P2P docker exec -e DISPLAY=:11 orcacad-gui python3 /tmp/check-gui-sketching.py
|
||||
|
||||
**F2P.** `scripts/CAD/check-gui-click-edit.py`. For each of Line, Rectangle, Circle, Slot,
|
||||
Polygon, Ellipse and Rounded rectangle: arm the tool, draw it, and type a value that differs
|
||||
from the prefill WITHOUT clicking the field. Assert the committed value equals the typed value.
|
||||
The ladder must FAIL against unmodified cad-mainline — that is what proves it asserts something.
|
||||
|
||||
**P2P.** `scripts/CAD/check-gui-sketching.py`, the existing gesture ladder, minus anything red at
|
||||
baseline. NOTE: it calls `focus_field()` — one click into the field before typing — which is the
|
||||
workaround this whole task removes. It stays green as a regression guard; it is NOT evidence.
|
||||
|
||||
**Test Integrity Constraint.** `focus_field()` in check-gui-sketching.py must NOT be deleted to
|
||||
make things pass, and check-gui-click-edit.py must NOT be weakened. Either invalidates the run.
|
||||
|
||||
## 3. VERIFICATION COMMANDS
|
||||
1. Static: `docker exec orcacad-gui ninja -C /OrcaSlicer/build orca-slicer` (warnings delta only;
|
||||
this repo configures no linter — the compiler is the static gate. Absolute-zero is NOT the gate.)
|
||||
2. Harness: `docker exec -e DISPLAY=:11 orcacad-gui python3 /tmp/check-gui-click-edit.py --attach`
|
||||
3. Regression: `docker exec -e DISPLAY=:11 orcacad-gui python3 /tmp/check-gui-sketching.py`
|
||||
|
||||
## 4. CONVERGENCE LOOP — ceiling 8 iterations
|
||||
EDIT (scoped) -> EXECUTE S1..S5 -> PARSE the ladder's per-tool assertions and the [UX]/[KEYTRACE]
|
||||
lines -> PATCH from the parsed cause. On ceiling without convergence: stop, report the last diff
|
||||
and the unresolved failure set. Do not report success.
|
||||
|
||||
F2P authoring exception: check-gui-click-edit.py is writable, and must be shown RED against
|
||||
unmodified source before any source edit counts.
|
||||
|
||||
## 5. TERMINATION CRITERIA
|
||||
- [ ] S2 exits 0, and introduces no compiler warning absent from the baseline.
|
||||
- [ ] S4 ALL_PASSED — every tool commits the typed value, no click into the field.
|
||||
- [ ] S5 shows zero regressions against its recorded baseline pass count.
|
||||
- [ ] F2P proven red without the fix (source stashed, ladder re-run, must FAIL).
|
||||
|
||||
## 6. GUARDRAILS
|
||||
Zero-assumption: no completion claim without captured stdout and exit codes. Oracle supremacy:
|
||||
the ladder's verdict overrides my judgement. Blast radius: §1 files only. Baseline obligation:
|
||||
run §3 once before the first edit and record it.

# OrcaSlicer system profiles
|
||||
|
||||
A bundle is `resources/profiles/<Vendor>.json` plus `<Vendor>/`. The vendor id is the
|
||||
filename stem, not the index's display `name`. The index is the loader's only entry point:
|
||||
unindexed presets never load. `OrcaFilamentLibrary` is the shared filament bundle;
|
||||
`blacklist.json` is data, not a bundle.
|
||||
|
||||
## Choose the reference for the task
|
||||
|
||||
Read the relevant reference before editing; load others only when the task crosses those areas.
|
||||
Paths below are relative to this skill. Commands run from the repository root.
|
||||
|
||||
| Task | Read |
|
||||
| --- | --- |
|
||||
| Add or tune a filament, brand or material; fix compatibility / alias shadowing | [filament-profiles.md](references/filament-profiles.md) |
|
||||
| Add a printer or nozzle; change models, variants, assets or extruder vectors | [machine-profiles.md](references/machine-profiles.md) |
|
||||
| Add a quality tier or tune a process | [process-profiles.md](references/process-profiles.md) |
|
||||
| Create a vendor bundle; diagnose loading or inheritance; migrate preset names | [vendor-bundle.md](references/vendor-bundle.md) |
|
||||
| Change ids; diagnose AMS identity | [ids.md](references/ids.md), then `docs/HLSD/filament_id.md` for identity changes |
|
||||
| Review a profile diff | [review-checklist.md](references/review-checklist.md) |
|
||||
| Run checks, interpret failures, test another tree or verify in the app | [validation.md](references/validation.md) |
|
||||
|
||||
## Golden rules
|
||||
|
||||
1. **Bump every changed bundle's `version`**, including `OrcaFilamentLibrary.json` when affected.
|
||||
Increment the last component; carry `.99` into the third component (`02.04.00.99` →
|
||||
`02.04.01.00`). The updater requires a strictly newer version. CI does not check this.
|
||||
2. **Register every preset, bases included, parents before children.** `update-index` generates
|
||||
the four `*_list` arrays; `check` requires its output. Index names must equal file `name` fields.
|
||||
3. **Generate ids; never invent or copy them.** Keep existing ids during ordinary tuning. New
|
||||
presets normally omit them until `generate-id`; bases must have no `setting_id`.
|
||||
BBL's authoritative `setting_id` and a wrongly inherited `filament_id` need the explicit
|
||||
handling in [ids.md](references/ids.md).
|
||||
4. **Load failures can discard a whole vendor bundle.** Broken `inherits`, missing indexed files,
|
||||
duplicate names, invalid model/variant references and unresolved filament ids affect more than
|
||||
the edited preset. Inheritance stays within a bundle, except filaments may inherit the library.
|
||||
5. **Preserve shipped selectable names.** Renaming, deleting or changing `instantiation` from
|
||||
`"true"` to `"false"` needs `renamed_from` on a selectable successor. It is a `;`-separated string;
|
||||
update in-tree references too. See [migration rules](references/vendor-bundle.md#renamed_from).
|
||||
6. **Compatibility uses exact printer variant names.** Every instantiated non-library filament
|
||||
needs a non-empty `compatible_printers` in its own file. Library fallbacks may omit it;
|
||||
library printer-specific tunes use a non-empty list. Keep same-product tunes disjoint.
|
||||
7. **Preset values are strings or arrays of strings.** Use `"instantiation": "false"`, not `false`.
|
||||
Model `nozzle_diameter` is a `;`-separated string; machine `nozzle_diameter` is an array.
|
||||
Wrong types can abort loading; see [failure scopes](references/vendor-bundle.md#failure-modes-ranked-by-blast-radius).
|
||||
8. **Verify setting keys against the code.** Unknown keys are silently discarded. Check
|
||||
`PrintConfig.cpp` definitions and `PrintConfigDef::handle_legacy`; neighbours can contain dead
|
||||
keys. `normalize` removes known obsolete keys, but does not detect arbitrary misspellings.
|
||||
9. **Run the full profile checks before reporting completion.** A vendor-scoped pass is only a
|
||||
development loop. Review also covers version bumps, assets, non-default processes and hardware
|
||||
tuning that CI cannot establish.
|
||||
|
||||
## Creating or modifying a profile
|
||||
|
||||
1. **Inspect the diff and neighbouring presets.** Read their `name`, parent chain and children;
|
||||
edits to a base or a leaf with descendants propagate. Match the bundle's structure and write
|
||||
only overrides. New files use tab indentation, LF and a trailing newline; preserve unrelated
|
||||
formatting in existing files. Match filename case exactly and use cross-platform names.
|
||||
2. **Author explicit metadata.** Set `type` yourself, especially for `machine` vs `machine_model`.
|
||||
Use `"from": "system"` and string `instantiation` on config presets. Omit ids on new presets
|
||||
unless [ids.md](references/ids.md) requires special handling; retain them on existing ones.
|
||||
Complete compatibility, defaults, assets and any rename migration using the task reference.
|
||||
3. **Bump the version**, then run the authoring commands in order for each affected bundle:
|
||||
|
||||
```bash
|
||||
python3 scripts/orca_profile_tool.py normalize --vendor "<Vendor>"
|
||||
python3 scripts/orca_profile_tool.py update-index --vendor "<Vendor>"
|
||||
python3 scripts/orca_profile_tool.py generate-id --vendor "<Vendor>"
|
||||
python3 scripts/orca_profile_tool.py check
|
||||
```
|
||||
|
||||
Writing commands support `--dry-run`. Inspect their diffs: `normalize` changes content and can
|
||||
reformat entire files. Stop and resolve command errors before proceeding.
|
||||
|
||||
**Do not use `trim` in this workflow:** it can delete newly authored, unindexed profiles.
|
||||
Do not use `normalize --force` for routine edits.
|
||||
4. **Validate:**
|
||||
|
||||
```bash
|
||||
./scripts/check_profile.sh --vendor "<Vendor>" # development loop
|
||||
./scripts/check_profile.sh # full tree before the PR
|
||||
```
|
||||
|
||||
On Windows use `py -3` instead of `python3`, and `scripts\check_profile.bat -Vendor "<Vendor>"`
|
||||
/ `scripts\check_profile.bat`. Logs: `.test/check_profiles/logs/<check>.log`.
|
||||
Id checks remain tree-wide under `--vendor`; filament-only bundles skip the default slice check.
|
||||
See [validation.md](references/validation.md) for flags, coverage and error remedies.
|
||||
5. **Verify the changed behavior.** Slice newly added non-default processes explicitly, and
|
||||
[test in the app](references/validation.md#testing-in-the-app) for selection or UI behavior.
|
||||
Report checks actually run, failures/skips and any hardware tuning still unverified.
|
||||

||||

compatibility; `src/libslic3r/PrintConfig.cpp` for setting types and legacy handling;
|
||||
`src/dev-utils/OrcaSlicer_profile_validator.cpp` and `.github/workflows/check_profiles.yml` for
|

validation coverage. `docs/HLSD/filament_id.md` defines filament identity. The

# Filament profiles and OrcaFilamentLibrary
|
||||
|
||||
`OrcaFilamentLibrary` is the filament-only bundle the loader reads **first**; its config map
|
||||
becomes the base bundle, so any vendor may inherit a library preset by name. It is the only cross-bundle
|
||||
parent — vendor-to-vendor inheritance always fails.
|
||||
|
||||
## Where a filament goes
|
||||
|
||||
| Contribution | Location |
|
||||
| --- | --- |
|
||||
| Generic material for all printers | `OrcaFilamentLibrary/filament/Generic <mat> @System.json` |
|
||||
| A brand's product, all printers | `OrcaFilamentLibrary/filament/<Brand>/` |
|
||||
| A brand's tune for one printer | `OrcaFilamentLibrary/filament/<Brand>/<PrinterVendor>/` — recommended; `<PrinterVendor>/filament/<Brand>/` also works |
|
||||
| A printer vendor's tune of a generic or its own product | `<Vendor>/filament/` |
|
||||
|
||||
Both locations for the last-but-one row are supported: `OrcaFilamentLibrary/filament/<Brand>/<PrinterVendor>/<Name>.json`
|
||||
(the shape the wiki shows) and `<PrinterVendor>/filament/<Brand>/`. The library path is the one a
|
||||
filament vendor should contribute to — `OrcaFilamentLibrary/filament/<Brand>/` is the brand's own
|
||||
folder, while a printer vendor's folder belongs to that printer vendor. Brand tunes do ship under
|
||||
printer vendors' folders today (Polymaker and SUNLU among others).
|
||||
|
||||
Library layout: `filament/base/fdm_filament_*.json` type roots, root-level `Generic <mat> @System.json`
|
||||
generics, and one subfolder per brand, which may nest printer-specific tunes one level deeper. Adding
|
||||
a brand means adding a folder here; the folder name is a directory label only — `filament_vendor` inside the JSON is the real vendor string.
|
||||
|
||||
## The three-part shape
|
||||
|
||||
```jsonc
|
||||
// Fiberon PA6-CF @base.json — the product root, holds identity + material values
|
||||
{ "type": "filament", "name": "Fiberon PA6-CF @base", "from": "system",
|
||||
"instantiation": "false", "inherits": "fdm_filament_pa",
|
||||
"filament_id": "OFkOviHk", // generated here; variants inherit it
|
||||
"filament_vendor": ["Polymaker"], "filament_type": ["PA6-CF"], /* … */ }
|
||||
|
||||
// Fiberon PA6-CF @System.json — the selectable shim, 7 keys
|
||||
{ "type": "filament", "name": "Fiberon PA6-CF @System", "from": "system",
|
||||
"instantiation": "true", "inherits": "Fiberon PA6-CF @base",
|
||||
"setting_id": "…", "compatible_printers": [] }
|
||||
|
||||
// <PrinterVendor>/filament/Polymaker/Fiberon PA6-CF @BBL X1C.json — a printer tune
|
||||
{ … "inherits": "Fiberon PA6-CF @base", "filament_max_volumetric_speed": ["14"],
|
||||
"compatible_printers": ["Bambu Lab X1 Carbon 0.4 nozzle", …] }
|
||||
```
|
||||
|
||||
- `@base` is the convention for a root. A base carries **no** `setting_id`, no `compatible_printers`, no
|
||||
`filament_settings_id`. Only the `setting_id` half is enforced, and nothing violates it; the other two
|
||||
are unchecked and plenty of bases still carry them. Do not copy that from a neighbouring file.
|
||||
- Every `@System` must be `"instantiation": "true"`. DREMC ships `@System` presets set to `"false"`,
|
||||
which therefore ship but can never be selected; no check catches it.
|
||||
- A duplicated brand `@base` across bundles is normal and intentional (`Fiberon PA6-CF @base` exists in
|
||||
both the library and BBL with the same id, differing only in MVS) — bases never enter the preset
|
||||
collection, so there is no duplicate-name error.
|
||||
- You may inherit from an instantiated preset as well as from a base; it is common.
|
||||
|
||||
## The two most common contributions
|
||||
|
||||
**A printer vendor tuning a generic.** Keep the `Generic X` base name so the alias shadows the library
|
||||
preset on your printers, inherit `Generic X @System`, declare **no** `filament_id` (inheriting the
|
||||
library's is correct — the product really is the library's generic), and give it a non-empty
|
||||
`compatible_printers` in its own body:
|
||||
|
||||
```jsonc
|
||||
// <Vendor>/filament/Generic PETG @Acme One 0.4 nozzle.json
|
||||
{ "type": "filament", "name": "Generic PETG @Acme One 0.4 nozzle", "from": "system",
|
||||
"instantiation": "true", "inherits": "Generic PETG @System",
|
||||
"filament_flow_ratio": ["0.95"], "filament_max_volumetric_speed": ["10"],
|
||||
"compatible_printers": ["Acme One 0.4 nozzle"] }
|
||||
```
|
||||
|
||||
**A printer vendor's own branded product.** Give it a `@base` root so `generate-id` can mint the id (see
|
||||
[ids.md](ids.md) — inheriting `Generic X @System` directly makes the id unfixable by the tool), then one
|
||||
instantiated leaf per printer in the same bundle. No `@System` shim: that is only for a product entering
|
||||
OrcaFilamentLibrary.
|
||||
|
||||
```jsonc
|
||||
// <Vendor>/filament/Acme Aura PETG @base.json — instantiation false, no setting_id
|
||||
{ "type": "filament", "name": "Acme Aura PETG @base", "from": "system",
|
||||
"instantiation": "false", "inherits": "fdm_filament_pet",
|
||||
"filament_vendor": ["Acme"], "filament_type": ["PETG"] } // filament_id minted here
|
||||
|
||||
// <Vendor>/filament/Acme Aura PETG @Acme One 0.4 nozzle.json
|
||||
{ "type": "filament", "name": "Acme Aura PETG @Acme One 0.4 nozzle", "from": "system",
|
||||
"instantiation": "true", "inherits": "Acme Aura PETG @base",
|
||||
"filament_max_volumetric_speed": ["11"],
|
||||
"compatible_printers": ["Acme One 0.4 nozzle"] }
|
||||
```
|
||||
|
||||
Omit `filament_settings_id` from new presets — it is runtime bookkeeping the app rewrites to the preset
|
||||
name.
|
||||
|
||||
## `compatible_printers`
|
||||
|
||||
- **Library fallbacks:** empty `[]` or absent, so they are offered on all printers except where
|
||||
[alias shadowing](#alias-shadowing) supplies a printer-specific tune.
|
||||
- **Library printer-specific tunes:** non-empty, listing exact printer **variant** names. These can
|
||||
supersede a same-alias fallback just like a tune in a printer vendor's bundle.
|
||||
- **Instantiated filaments in every other vendor:** non-empty, listing exact printer **variant** names.
|
||||
Enforced twice but not identically: the C++ `has_errors` reads the *flattened* config, so an inherited list satisfies it,
|
||||
while the Python check reads the file's **own** key. Write the list in the file itself. This is the
|
||||
most common filament CI failure.
|
||||
- Emptying it to "make it apply everywhere" fails that check *and* creates a duplicate-`filament_id`
|
||||
collision against the library generic on every printer.
|
||||
- Copying a base's full printer list onto a nozzle-specific variant produces duplicate combobox entries —
|
||||
a real shipped bug twice over.
|
||||
|
||||
## Alias shadowing
|
||||
|
||||
A printer-specific filament in either the library or a vendor bundle supersedes the library fallback
|
||||
on the printers it lists. The matching key is the **alias**: the preset name up to the **first** `@`,
|
||||
right-trimmed (no `@` → the whole name). So
|
||||
`QIDI ABS-GF@Q2-Series` aliases to `QIDI ABS-GF`.
|
||||
|
||||
A library preset with an empty `compatible_printers` collects, into `m_excluded_from`, every printer named
|
||||
by any same-alias preset that *has* a non-empty list, and is then hidden on those printers.
|
||||
|
||||
Two consequences:
|
||||
|
||||
- **Only an unrestricted library fallback can be shadowed.** Two printer-specific presets sharing
|
||||
an alias do not exclude each other — overlapping lists for the same product trip the
|
||||
duplicate-`filament_id` check instead.
|
||||
- This is why adding `Generic PLA @<printer>` to a vendor silently removes the library `Generic PLA`
|
||||
from that printer. Intended — and the reason a vendor tuning a generic must **keep the `Generic X`
|
||||
base name**.
|
||||
|
||||
The literal spelling `Generic <mat> @System` is load-bearing beyond shadowing: `find_preset2` rewrites an
|
||||
unresolved name containing "Generic" into that form and retries against the library, which is how 3MF
|
||||
and project recovery works.
|
||||
|
||||
## `filament_id`, `filament_vendor`, `filament_type`
|
||||
|
||||
`filament_id` is minted from the triple `(filament_vendor, filament_type, name-before-first-@)`.
|
||||
`filament_vendor` and `filament_type` are therefore **identity, not decoration** — editing either
|
||||
re-mints the id. Read `docs/HLSD/filament_id.md` before changing any of them, and see
|
||||
[ids.md](ids.md) for the tooling.
|
||||
|
||||
A filament with no resolvable `filament_id` anywhere in its `inherits` chain is a **hard load error** that
|
||||
discards the vendor bundle. The id inherits across bundles, so a vendor's `Generic ABS @X` inheriting
|
||||
`Generic ABS @System` gets the library's id for free; a vendor's own product must resolve its own.
|
||||
|
||||
- `filament_type` **must be a JSON array** — the one vector key the Python check enforces. A scalar
|
||||
`"PP"` once hung the filament/printer selection UI.
|
||||
- It is an **open** enum: an unlisted value is accepted silently and falls back to 190–300 °C defaults
|
||||
and adhesion 1.0. Off-list values do ship. Prefer a value from `MaterialType::all()` in
|
||||
`src/libslic3r/MaterialType.cpp`, or add a row there.
|
||||
- Generics use `filament_vendor: ["Generic"]`, which `fdm_filament_common` already defaults to.
|
||||
|
||||
## `"nil"`
|
||||
|
||||
Legal in any key whose `ConfigOptionDef` is `nullable`. In a filament preset that is most of the
|
||||
`filament_*` family, plus `long_retractions_when_ec` and `retraction_distances_when_ec`. About half are
|
||||
the extruder overrides (`filament_retraction_length`, `filament_z_hop`, `filament_wipe`,
|
||||
`filament_retract_*`, `filament_retraction_speed`, `filament_deretraction_speed`,
|
||||
`filament_retraction_minimum_travel`, `filament_wipe_distance`, `filament_long_retractions_when_cut`,
|
||||
`filament_retraction_distances_when_cut`, …), where `nil` means *keep the printer/extruder's own value*.
|
||||
The rest are ordinary nullable options (`filament_flow_ratio`, `filament_flush_temp`,
|
||||
`filament_adaptive_volumetric_speed`, …) where it means *unset*.
|
||||
|
||||
Anywhere else it throws `Deserializing nil into a non-nullable object`. To not set a non-nullable key,
|
||||
omit it — do not write `nil`.
|
||||
|
||||
## What to review per nozzle
|
||||
|
||||
Across `@X` / `@X 0.N nozzle` sibling pairs the keys that differ, most often first, are
|
||||
`filament_max_volumetric_speed`, `filament_retraction_length`, `slow_down_min_speed`,
|
||||
`filament_flow_ratio`, `slow_down_layer_time`, `nozzle_temperature` and `pressure_advance`.
|
||||
`filament_cost`, `filament_density`, `filament_type` and `filament_vendor` belong on the `@base` and
|
||||
should not appear in a printer tune.
|
||||
|
||||
Use measured values for the material, hotend, extruder and nozzle combination. Neither maximum
|
||||
volumetric speed nor pressure advance has a universal nozzle-only lookup table. When cloning a
|
||||
0.4 preset for a 0.2 nozzle, explicitly revisit flow limits; do not infer a pressure-advance value
|
||||
or a required direction of change from diameter alone.
|
||||
|
||||
## Style
|
||||
|
||||
Overrides, not full copies: a typical instantiated filament preset carries around a dozen non-meta keys,
|
||||
and a library leaf two or three. Presets that restate fifty-plus keys from their parent do still ship —
|
||||
Phrozen's single filament preset is that style — but they are the pattern to move away from, not to
|
||||
copy. Commit `6943b6ddc3` is the stated model (flip true bases to `instantiation: "false"`, strip
|
||||
`compatible_printers`/`setting_id`/`filament_settings_id`, add `renamed_from` on the survivor).
|
||||
|
||||
Prefer the library's `fdm_filament_*` bases over a vendor-local copy. Phrozen's local
|
||||
`fdm_filament_common` has drifted from the library's.
|
||||
|
||||
Canonical key order, written by `orca_profile_tool.py normalize` when it rewrites a file: `type`, `name`,
|
||||
`renamed_from`, `inherits`, `from`, `setting_id`, `filament_id`, `instantiation`, then everything else in
|
||||
the order you wrote it. Not enforced — a file that leads with `compatible_printers` passes `check`.
|
||||
|
||||
**Every vector-typed (`co*s`) key must be a JSON array.** Only `filament_type` is an outright error, but
|
||||
`normalize` silently arrayifies five more (`filament_cost`, `filament_density`,
|
||||
`temperature_vitrification`, `filament_max_volumetric_speed`, `filament_vendor`) and `check` fails when
|
||||
it would. Every other vector key is on you — including `filament_start_gcode`, `filament_end_gcode`,
|
||||
`filament_extruder_variant`, `compatible_printers` and the plate temperatures.
|
||||
|
||||
## Bed temperature is twelve keys, not one
|
||||
|
||||
There is no single "bed temperature". Which plate key applies depends on `curr_bed_type`, whose six
|
||||
selectable values (`btPC`, `btEP`, `btPEI`, `btPTE`, `btPCT`, `btSuperTack`; `btDefault` maps to no key)
|
||||
`get_bed_temp_key()` turns into `cool_plate_temp`, `eng_plate_temp`, `hot_plate_temp`,
|
||||
`textured_plate_temp`, `textured_cool_plate_temp` and `supertack_plate_temp` — each with an
|
||||
`*_initial_layer` twin.
|
||||
|
||||
`textured_cool_plate_temp` is the one most often forgotten. A printer with `support_multi_bed_types` off
|
||||
hides the selector, and the printer preset's
|
||||
`default_bed_type` decides which plate is selected for it, but `curr_bed_type` can still hold a stale
|
||||
value carried over from another printer — so set every plate the printer plausibly has, as the sibling
|
||||
presets in the bundle do.

# `setting_id` and `filament_id`
|
||||
|
||||
Orca-generated ids are deterministic hashes of identity. **Never invent an id or copy a sibling's
|
||||
`setting_id`.** Use `scripts/orca_profile_tool.py`; the two special cases are
|
||||
[a wrongly inherited filament id](#what-generate-id-does-and-does-not-fix) and
|
||||
[BBL's authoritative setting ids](#bbls-exception-precisely).
|
||||
|
||||
`docs/HLSD/filament_id.md` is the authoritative design document for `filament_id` — the id landscape, the
|
||||
checks CI runs, and the Bambu catalog map. This page is the tooling half.
|
||||
|
||||
| | `setting_id` | `filament_id` |
|
||||
| --- | --- | --- |
|
||||
| Identifies | one selectable preset | one filament **product** |

| Key hashed | `<vendor folder>/<type>/<name>` | `filament_product/<filament_vendor>/<filament_type>/<name-before-@>` |
|
||||
| Shape | 16 base62 chars | `OF` + 6 base62 chars |
|
||||
| Required on | every `instantiation: "true"` preset | every **instantiated** filament, own or inherited |
|
||||
| Forbidden on | bases (`instantiation != "true"`) | — (a base is exactly where it belongs) |
|
||||
| Scope | globally unique across the tree | shared by every variant of the product, in every bundle |
|
||||
|
||||
`<type>` is `machine` / `process` / `filament` — the vendor is the **folder** name (`BBL`), not the
|
||||
display name (`Bambulab`). Renaming a preset changes its `setting_id`; renaming a filament, or editing
|
||||
its `filament_vendor` or `filament_type`, also changes its `filament_id`.
|
||||
|
||||
## The tool
|
||||
|
||||
Use `scripts/orca_profile_tool.py` with a subcommand:
|
||||
|
||||
| Command | Does |
|
||||
| --- | --- |
|
||||
| `check` | everything CI's `profile_tool` step runs — see [validation.md](validation.md) |
|
||||
| `generate-id` | writes `setting_id` and `filament_id` |
|
||||
| `normalize` | rewrites profile files into their canonical shape |
|
||||
| `trim` | deletes profile files no `<vendor>.json` list references |
|
||||
| `update-index` | rebuilds the `*_list` sections from the files on disk |
|
||||
|
||||
The order after adding, renaming or deleting files — each step feeds the next, so it is not
|
||||
interchangeable — is `normalize` → `update-index` → `generate-id` → `check`.
|
||||
The [authoring workflow](../SKILL.md#creating-or-modifying-a-profile) has the commands.
|
||||
|
||||
> **`trim` deletes.** It removes every profile file the index does not list — including the one you just
|
||||
> added and have not registered yet. Register first, or skip `trim` entirely; it is a cleanup sweep, not
|
||||
> part of landing a profile. Preview with `--dry-run`.
|
||||
|
||||
**Register, then mint.** The `filament_id` pass reads `<Vendor>.json`'s `filament_list`, not the
|
||||
filesystem (the `setting_id` pass walks the filesystem, so a bundle whose index has not landed yet is
|
||||
still assignable). A new filament file is therefore invisible to `generate-id`'s filament_id pass until
|
||||
it is registered — its `setting_id` is written regardless.
|
||||
|
||||
- `--dry-run` works on every writing command (`generate-id`, `normalize`, `trim`, `update-index`)
|
||||
and writes nothing.
|
||||
- `--filament-id` / `--setting-id` narrow `generate-id`; they exclude each other, and passing neither
|
||||
writes both.
|
||||
- `--vendor` is repeatable and narrows **only what is written** — the id is a function of the triple
|
||||
alone, so a narrowed run writes exactly what a full run would. An unknown vendor exits 1 before any
|
||||
write. `--vendor` on `check` narrows the per-vendor checks only; the `setting_id` and `filament_id`
|
||||
passes stay tree-wide.
|
||||
- `--profiles DIR` points any command at another tree — see
|
||||
[Checking a copy of the tree](validation.md#checking-a-copy-of-the-tree).
|
||||
- `--profile-type` narrows `normalize`, `trim` and `update-index` to `machine_model`, `process`,
|
||||
`filament` or `machine`.
|
||||
- Exit codes: 0 clean, 1 errors found (`generate-id` still writes what it could), 2 argparse misuse.
|
||||
- Output is ANSI-coloured; searching for the literal `[ERROR]` still works.
|
||||
|
||||
`generate-id` is **idempotent and byte-preserving** — BOM and CRLF kept, one key line touched per pass.
|
||||
A legitimate `generate-id` diff is one or two changed lines per file: a new instantiated filament gets
|
||||
both a `filament_id` and a `setting_id`, and a BBL file with a misspelled `settings_id` has that line
|
||||
dropped and its value restored under the right key. `normalize` is the opposite by design — it rewrites
|
||||
whole files into canonical shape — which is why `check` demands it already be a no-op. Some bundles have
|
||||
CRLF committed (OrcaFilamentLibrary, Anycubic and RH3D among them), so a `normalize` pass there rewrites
|
||||
every line — read the diff before committing it.
|
||||
|
||||
On a clean tree `check` and `generate-id --dry-run` both exit 0 with zero findings. That is the
|
||||
baseline to restore before opening a PR.
|
||||
|
||||
## What `generate-id` does and does not fix
|
||||
|
||||
Writes:
|
||||
|
||||
- a `setting_id` into any instantiated preset that lacks one, or whose value does not match the formula;
|
||||
- strips a `setting_id` from a base;
|
||||
- deletes the misspelled `settings_id` key;
|
||||
- a `filament_id` into the id-less **root(s)** of an instantiated filament that resolves none;
|
||||
- rewrites a **declared** `filament_id` that is not the mint of its own triple.
|
||||
|
||||
Refuses to write (reports only): a base62 collision between two products, an empty `filament_vendor` or
|
||||
`filament_type`, a broken `inherits` chain, roots of one filament resolving divergent `(vendor, type)`
|
||||
pairs.
|
||||
|
||||
**Does not fix: a preset that *inherits* a wrong `filament_id`.** This is check 2b, and it is the trap
|
||||
most likely to bite. It happens when a branded filament inherits a generic for its settings:
|
||||
|
||||
```jsonc
|
||||
{ "name": "Phrozen Aura PETG @Phrozen Arco 0.4 nozzle",
|
||||
"inherits": "Generic PETG @System" } // resolves the OFL generic's id — wrong product
|
||||
```
|
||||
|
||||
The preset resolves *an* id, so `generate-id` neither inserts nor rewrites, and `check` fails with
|
||||
`inherits filament_id "X" but its own triple "V/T/N" mints "Y"`.
|
||||
|
||||
Two fixes, in order of preference:
|
||||
|
||||
1. **Give the product a `@base` root** inheriting a material base (`fdm_filament_pet`,
|
||||
`fdm_filament_pla`, …). No `fdm_filament_*` base carries a `filament_id`, so the filament now resolves
|
||||
none and `generate-id` mints it for you. This is also the shape the rest of the tree uses.
|
||||
2. **Declare the tool-computed key on the preset itself.** Use the expected value reported by `check`
|
||||
or compute it with the function below; this is not a manually chosen id. Make sure the preset
|
||||
resolves the right `filament_vendor` and `filament_type` first — with
|
||||
neither set, the triple resolves through the generic parent and the branded product is minted
|
||||
under vendor `Generic`. If you need the id before the file exists:
|
||||
|
||||
```bash
|
||||
python3 -c "import sys; sys.path.insert(0,'scripts'); from orca_profile_tool import generate_filament_id as g; print(g('Polymaker','PLA','PolyLite PLA'))"
|
||||
# -> OF5CgdDq
|
||||
```
|
||||
|
||||
The quoting works unchanged in cmd and PowerShell; only swap `python3` for `py -3`.
|
||||
|
||||
The `setting_id` equivalent is `generate_preset_setting_id('<vendor folder>', '<type>', '<name>')`.
|
||||
|
||||
## BBL's exception, precisely
|
||||
|
||||
`RESERVED_VENDORS = {"BBL"}` covers **`setting_id` assignment only**, keyed on the *folder* name:
|
||||
|
||||
- The tool never mints or replaces a BBL `setting_id`. A new instantiated BBL preset with no
|
||||
`setting_id` therefore **cannot be fixed by the tool**, yet the presence rule still applies to it —
|
||||
carry over Bambu's authoritative id by hand.
|
||||
- BBL is not exempt from anything else: bases still get their `setting_id` stripped, ids must still be
|
||||
globally unique, and BBL `filament_id`s are minted like everyone else's — every one of them is an
|
||||
`OF*`.
|
||||
|
||||
## Ids other systems compose
|
||||
|
||||
No id from another system is the mint of a triple, so `check` rejects it like any other bad id — same
|
||||
error, same remedy, whoever wrote it. Three such spaces exist near the tree; recognise them so you do
|
||||
not copy one into a profile:
|
||||
|
||||
- **Bambu's `GF*` catalog** — external and opaque, correlated to Orca's ids by the generated
|
||||
`resources/printers/bambu_filament_ids.json`. `GF` is a *prefix*, not a spelling the tree avoids: most
|
||||
BBL `setting_id`s start with `G`, and `blacklist.json` and
|
||||
`BBL/filament/filaments_color_codes.json` both reference Bambu catalog ids by design. The rule is
|
||||
about `filament_id` and nothing else.
|
||||
- **Qidi's `QD_*`** — composed at runtime by the box (`QD_<series>_<vendor>_<typeidx>`), not a preset id.
|
||||
- **`P` + 7 hex, and `"null"`** — what `CreatePresetsDialog.cpp` gives a *user*-created filament.

# Printer models and variants
|

|
||||
Both live in `resources/profiles/<Vendor>/machine/*.json`; models go in `machine_model_list`, variants
|
||||
and shared bases in `machine_list`. Every one of them is registered. Some vendors (Elegoo, Eryone,
|
||||
InfiMech, FlyingBear) nest a further subfolder under `machine/`, so recurse rather than globbing
|
||||
`machine/*.json`.
|
||||
|
||||
## A `machine_model` is not a config preset
|
||||
|
||||
It is parsed by a hand-written key switch, and only these keys are stored (`version` and `url` are
|
||||
matched and discarded):
|
||||
|
||||
`name`, `model_id`, `nozzle_diameter`, `machine_tech`, `family`, `bed_model`, `bed_texture`,
|
||||
`hotend_model`, `default_materials`, `not_support_bed_type`, `image_bed_type`,
|
||||
`bottom_texture_end_name`, `bottom_texture_rect`, `bottom_texture_rect_longer`, `middle_texture_rect`,
|
||||
`use_double_extruder_default_texture`.
|
||||
|
||||
**Everything else is silently dropped.** Only `name` and `nozzle_diameter` are required. Dead keys ship
|
||||
on real models today — `url`, `default_bed_type`, even a `desciption` typo — so a neighbour carrying a
|
||||
key is no evidence it does anything. Printer config options belong on the `machine` preset, never here.

| `default_materials` | `;`-separated filament **preset names**.

Not `,`; case-sensitive (`@System`). `check` fails on a dangling name here or in `default_filament_profile`. |
|

| `family` | a wizard grouping label only; give every model one. |

### Assets
|
||||
|
||||
`bed_model`, `bed_texture` and `hotend_model` are paths relative to the **vendor folder** (by id).
|
||||
Majority convention: `<Model>_buildplate_model.stl` and `<Model>_buildplate_texture.svg`. An empty string
|
||||
is the legal "none", and is the norm for `hotend_model`.
|
||||
|
||||
**Nothing checks that the file exists.** A missing `hotend_model` falls back to
|
||||
`resources/profiles/hotend.stl`; a missing `bed_model`/`bed_texture` just renders nothing. Broken
|
||||
references already ship. Verify by hand.
|
||||
|
||||
Every model also has a `<Model>_cover.png` in the vendor folder — treat it as required, not optional.
|
||||
240×240 is the cap `scripts/optimize_cover_images.py` enforces and the size most covers already use.
|
||||
A missing cover degrades to a placeholder in both the wizard and the sidebar.
|
||||
|
||||
## The `machine` variant
|
||||
|
||||
```json
|
||||
{
|
||||
"type": "machine",
|
||||
"name": "Phrozen Arco 0.4 nozzle",
|
||||
"inherits": "fdm_machine_common",
|
||||
"from": "system",
|
||||
"setting_id": "lvaYKTUZr5C9jSwk",
|
||||
"instantiation": "true",
|
||||
"printer_model": "Phrozen Arco",
|
||||
"printer_variant": "0.4",
|
||||
"nozzle_diameter": ["0.4"],
|
||||
"default_print_profile": "0.20mm Standard @Phrozen Arco 0.4 nozzle",
|
||||
"default_filament_profile": ["Generic PLA @Phrozen Arco 0.4 nozzle"],
|
||||
"printable_area": ["0x0", "300x0", "300x300", "0x300"],
|
||||
"printable_height": "300"
|
||||
}
|
||||
```
|
||||
|
||||
Minimum viable key set: `type`, `name`, `from`, `instantiation`, `setting_id`, `inherits`,
|
||||
`printer_model`, `printer_variant`, `nozzle_diameter`, `printable_area`, `printable_height`,
|
||||
`default_print_profile`. The four keys without which the preset will not load at all are `name`,
|
||||
`instantiation`, `printer_model` and `printer_variant`; `default_filament_profile` is an array
|
||||
(`["Generic PLA @System"]`) and the model's `default_materials` a `;`-separated string. Unlike a
|
||||
`machine_model`, a `machine` **is** config-loaded, so a key belonging to another preset type is a
|
||||
reported error (a misspelled key is still silent).
|
||||
|
||||
### `printer_variant` — three hard rules
|
||||
|
||||
1. Non-empty, and an exact member of the model's `;`-separated `nozzle_diameter` list.
|
||||
2. `printer_model` non-empty and naming a model of this vendor.
|
||||
3. In validation mode, for instantiated presets only: split `printer_variant` on `+`, each token must
|
||||
start with a number (a trailing non-numeric suffix such as `HF` is ignored), and the resulting **set**
|
||||
must equal `set(nozzle_diameter)`.
|
||||
|
||||
Rules 1 and 2 are loader-enforced — failing either drops the preset *and* the whole bundle. Rule 3 only
|
||||
raises a validation error: the preset still loads, but the validator exits non-zero.
|
||||
|
||||
`nozzle_diameter` lists one entry **per physical nozzle**; `printer_variant` lists the **distinct**
|
||||
diameters joined with `+`. Snapmaker U1 is the worked case: `["0.4","0.4","0.6","0.6"]` against
|
||||
`"0.4+0.6"` — it passes because the comparison is on sets.
|
||||
|
||||
The conventional values are `0.2`, `0.25`, `0.4`, `0.5`, `0.6`, `0.8` and `1.0`. Suffixed forms
|
||||
(`0.4HF`, `0.6HF`, `0.8HF`, `0.4HS`) are Flashforge-only and the `+` form is rare. A variant is **not**
|
||||
required to be unique within a model — Volumic ships `EXO42 IDRE`, `… COPY MODE` and `… MIRROR MODE` all
|
||||
at `0.4` under the one model `EXO42 IDRE`.
|
||||
|
||||
The converse is **unchecked**: a nozzle size in the model's list with no matching variant is offered in
|
||||
the wizard and resolves to nothing. `Wanhao France`'s `D12 500 PRO M2 DIRECT` ships that bug today.
|
||||
|
||||
### Other fields worth knowing
|
||||
|
||||
- `default_print_profile` is a **scalar**, matched by exact preset name. Not a `;` list. The named
|
||||
process must be compatible with this printer through its resolved list or condition.
|
||||
`validate_slice` attempts to select it and rejects generic Default fallbacks, but compatibility
|
||||
updates can choose another compatible preset. Check the exact default reference yourself.
|
||||
- `default_filament_profile` is an **array**, one name per element.
|
||||
- `printable_area` is an array of `"XxY"` strings — four points for a rectangle, one per segment for a
|
||||
delta or circular bed.
|
||||
- `gcode_flavor` is usually set once in the base; `klipper`, `marlin`, `marlin2` and `reprapfirmware`
|
||||
cover nearly every shipped printer.
|
||||
- `printer_settings_id` is junk — most files carrying it disagree with their own name. Do not copy it
|
||||
when cloning a bundle.
|
||||
- `min_layer_height` / `max_layer_height` are **machine** keys (per extruder), never process keys.
|
||||
|
||||
## Bases
|
||||
|
||||
Nearly every machine-bearing vendor registers a base literally named `fdm_machine_common`, and Klipper
|
||||
vendors add `fdm_klipper_common` on top of it. Two levels is the usual depth.
|
||||
|
||||
**There is no leading-underscore convention for bases.**
|
||||
|
||||
## Adding a printer to an existing bundle
|
||||
|
||||
1. Choose the names first — model, variant(s), process(es); everything else references them.
|
||||
2. Add the model (`machine_model_list`) and one `machine` variant per nozzle; the minimum key sets are
|
||||
above. Bed assets and `<Model>_cover.png` go directly in `<Vendor>/`.
|
||||
3. Add at least one process per variant naming it in `compatible_printers`
|
||||
([process-profiles.md](process-profiles.md#adding-a-quality-tier-or-a-nozzles-processes)).
|
||||
4. Register everything (or run `update-index`), bump the version, run the id tool, validate.
|
||||
|
||||
## Adding a nozzle variant
|
||||
|
||||
1. Extend the model's `nozzle_diameter` (`"0.4"` → `"0.4;0.6"`).
|
||||
2. Add the variant preset. Either inherit the shared base (the usual choice) or the 0.4 sibling (Elegoo,
|
||||
BBL, Prusa and Qidi do this — smaller diff, but the sibling's edits now reach this file too).
|
||||
3. Override what actually changes with nozzle: `nozzle_diameter`, `printer_variant`,
|
||||
`default_print_profile`, `default_filament_profile`, `min_layer_height`/`max_layer_height`, and
|
||||
retraction if the vendor tunes it.
|
||||
4. Add at least one process for the new nozzle — see [process-profiles.md](process-profiles.md).
|
||||
5. Register both, bump the version, run the id tool, validate.
|
||||
|
||||
## Multi-extruder, IDEX and tool-changers
|
||||
|
||||
Per-extruder vectors are **silently resized** to the nozzle count, with no error. Padding repeats the
|
||||
**first** value, not the last — `["0.4","0.6"]` on a 4-nozzle machine becomes `0.4, 0.6, 0.4, 0.4`.
|
||||
Longer vectors are truncated.
|
||||
|
||||
Note the two sizing families: the plain per-extruder keys (`extruder_offset`, `extruder_colour`,
|
||||
`extruder_printable_height`, `min_layer_height`, `max_layer_height`, `nozzle_diameter`) are sized to the
|
||||
extruder count, while `printer_options_with_variant_1` (`retraction_length`, `z_hop`, `wipe`,
|
||||
`nozzle_type`, the rest of the retraction family) is sized to `printer_extruder_variant` instead.
|
||||
|
||||
- Give **one entry per extruder** for ordinary per-extruder vectors such as `extruder_offset`,
|
||||
`extruder_colour`, `min_layer_height` and `max_layer_height`; size the variant-dependent family
|
||||
to `printer_extruder_variant` instead.
|
||||
A single `["0x0"]` `extruder_offset` on a dual or multi-tool machine — which already ships — pads every
|
||||
toolhead to the same offset, so the offset never applies.
|
||||
- Overriding `nozzle_diameter` to a different count without re-stating every per-extruder vector is the
|
||||
other half of the trap — `Snapmaker U1 (0.4+0.6 nozzle)` inherits 5-entry vectors against 4 nozzles.
|
||||
|
||||
Copy targets: `Custom/machine/fdm_toolchanger_common.json` + `Custom/machine/MyToolChanger 0.4
|
||||
nozzle.json` (a clean minimal variant on a base that gives every vector five entries), and
|
||||
`Ratrig/machine/RatRig V-Core 4 IDEX 300 0.4 nozzle.json` for IDEX. The BBL extruder-variant machinery
|
||||
(`extruder_variant_list`, `printer_extruder_id`, `default_nozzle_volume_type`) is used by a handful of
|
||||
vendors — do not copy it into a new bundle (`nozzle_volume_type` itself is not a machine-preset key).
|
||||
|
||||
## Custom G-code
|
||||
|
||||
The keys are `machine_start_gcode`, `machine_end_gcode`, `change_filament_gcode`,
|
||||
`machine_pause_gcode`, `before_layer_change_gcode` and `layer_change_gcode`. Both a single string with
|
||||
embedded `\n` and a JSON array of lines are legal and both are in use — do not convert one into the
|
||||
other. Conditionals are `{if …}` / `{elsif …}` / `{else}` / `{endif}`; `{elsif}` is rare but real (Qidi's
|
||||
`layer_change_gcode` uses it).
|
||||
|
||||
Placeholder errors only surface when the config is actually expanded, which means `validate_slice`:
|
||||
|
||||
```bash
|
||||
./scripts/check_profile.sh --vendor "<Vendor>" validate_slice
|
||||
# Windows: scripts\check_profile.bat -Vendor "<Vendor>" validate_slice
|
||||
```
|
||||
|
||||
What the sweep covers is in [validation.md](validation.md#validate_slice); no `CP TOOLCHANGE START` in
|
||||
the output means `change_filament_gcode` never expanded.

# Process profiles
|
||||
|
||||
Processes live in `resources/profiles/<Vendor>/process/` — selectable leaves and shared bases alike, and
|
||||
every one of them is registered in `process_list`. There are no global processes shared across vendors.
|
||||
|
||||
## Naming
|
||||
|
||||
`"<layer height>mm <quality> @<target>"` — near-universal, so match it.
|
||||
|
||||
Follow the bundle's existing quality vocabulary. BBL's common ladder relates the quality word to
|
||||
the layer-height / nozzle ratio; it is a naming convention, not a loader constraint:
|
||||
|
||||
| Quality | Ratio | 0.2 nozzle | 0.4 | 0.6 | 0.8 |
|
||||
| --- | --- | --- | --- | --- | --- |
|
||||
| Extra Fine | 0.2× | — | 0.08 | — | — |
|
||||
| Fine | 0.3× | 0.06 | 0.12 | 0.18 | 0.24 |
|
||||
| Optimal | 0.4× | 0.08 | 0.16 | 0.24 | 0.32 |
|
||||
| Standard | 0.5× | 0.10 | 0.20 | 0.30 | 0.40 |
|
||||
| Draft | 0.6× | 0.12 | 0.24 | 0.36 | 0.48 |
|
||||
| Extra Draft | 0.7× | 0.14 | 0.28 | 0.42 | 0.56 |
|
||||
|
||||
This is the `fdm_process_single_<lh>_nozzle_<n>` ladder; 0.4 is commonly the unsuffixed nozzle default.
|
||||
Match neighbouring names rather than renaming shipped tiers to fit the table.
|
||||
|
||||
The `@target` is a human label, not a reference: most do not equal any real printer variant name.
|
||||
Compatibility comes from the resolved list or condition, not this label.
|
||||
|
||||
## Shape
|
||||
|
||||
A selectable leaf's only truly universal keys are `type`, `setting_id`, `name` and `instantiation`;
|
||||
`inherits` and `from` are near-universal — plus compatibility. No slicing key is universal; even
|
||||
`layer_height` is more often inherited than restated. A base has `type`, `name`, `instantiation`, almost
|
||||
always `from`, and **no** `setting_id`.
|
||||
|
||||
**Target shape: a 7-key leaf.** `OrcaArena` is the cleanest model —
|
||||
`fdm_process_common` → `fdm_process_arena_common` → `fdm_process_arena_<lh>_nozzle_<n>` → leaf, where the
|
||||
leaf carries only `type`, `name`, `inherits`, `from`, `setting_id`, `instantiation`,
|
||||
`compatible_printers`, and the per-nozzle base holds the layer height and all eight line widths.
|
||||
|
||||
BBL, WonderMaker and Z-Bolt are uniform in *layering* — every leaf inherits a base, names its printers
|
||||
directly and holds no layer height of its own — but not in key count. Imitate BBL's layering, not its
|
||||
content: its leaves carry doubled `print_extruder_variant` arrays that no single-variant vendor needs.
|
||||
|
||||
Nearly every vendor ships its own `fdm_process_common` as the inherits-less root. Those files are not
|
||||
identical; copying another vendor's version into a new bundle is normal.
|
||||
|
||||
Beware leaf-inherits-leaf: Prusa chains several levels deep through sibling leaves, and Elegoo and
|
||||
Flashforge do it too, so editing one selectable process silently changes others. Check a leaf's children
|
||||
before editing it.
|
||||
|
||||
## Compatibility
|
||||
|
||||
Most leaves set `compatible_printers` directly; some inherit it from a base, and Prusa's fall through to
|
||||
`compatible_printers_condition`. After resolving `inherits`, **every selectable process has one or the
|
||||
other** — that is the invariant to review against. Unlike filaments, inheriting `compatible_printers` is
|
||||
legitimate for a process, and no check enforces its presence.
|
||||
|
||||
- A non-empty `compatible_printers` makes `compatible_printers_condition` **dead code**. Use one or
|
||||
the other.
|
||||
- A condition that fails to parse means *compatible with everything* — a warning, not an error. A typo
|
||||
widens compatibility instead of narrowing it.
|
||||
- Matching is `boost::regex` **`regex_match`** — a full-string match, which is why every shipped
|
||||
condition wraps its keyword in `.*`. Because it is boost rather than `std`, `.` also spans the newlines
|
||||
inside `printer_notes`.
|
||||
- A `printer_notes` keyword that prefixes another model's keyword matches both. Prusa guards it:
|
||||
|
||||
```
|
||||
printer_notes=~/.*PRINTER_MODEL_COREONE[^_a-zA-Z0-9].*/ and nozzle_diameter[0]==0.4 and printer_notes=~/.*HF_NOZZLE.*/
|
||||
```
|
||||
|
||||
The `[^_a-zA-Z0-9]` exists because `PRINTER_MODEL_COREONE_L` also contains `PRINTER_MODEL_COREONE`.
|
||||
|
||||
`compatible_printers` is almost always one element. A leaf listing a whole model family is where a newly
|
||||
added printer is usually forgotten.
|
||||
|
||||
## What to review per nozzle
|
||||
|
||||
| Key group | Review |
|
||||
| --- | --- |
|
||||
| `line_width` and per-region widths | resolved widths suit the nozzle and layer height |
|
||||
| `layer_height`, `initial_layer_print_height` | within the printer's limits |
|
||||
| print speeds | consistent with flow limits and hardware tuning |
|
||||
| shell layers, wall loops, accelerations, support Z distances | preserve the intended thickness, motion and support behavior |
|
||||
|
||||
**A common starting pattern is nozzle + 0.02 mm**: 0.22 / 0.42 / 0.62 / 0.82 / 1.02. In that pattern, at 0.4,
|
||||
`inner_wall_line_width`, `sparse_infill_line_width`, `skin_infill_line_width` and
|
||||
`skeleton_infill_line_width` widen to 0.45 and `initial_layer_line_width` to 0.5; at 0.2,
|
||||
`initial_layer_line_width` widens to 0.25. Also derived, and easily missed:
|
||||
`ironing_inset = line_width / 2` (0.11 / 0.21 / 0.31 / 0.41).
|
||||
These are examples, not required values; preserve intentional vendor tuning and percentage/automatic
|
||||
widths, and validate their resolved values.
|
||||
|
||||
`min_layer_height` and `max_layer_height` are machine keys — no process file sets them.
|
||||
|
||||
## Slice-time content checks
|
||||
|
||||
`Print::validate()` enforces four rules at slice time:
|
||||
|
||||
1. `initial_layer_print_height` ≤ min `nozzle_diameter`
|
||||
2. `layer_height` ≤ min `nozzle_diameter` — *"Layer height cannot exceed nozzle diameter."*
|
||||
3. `line_width` and the seven per-region widths (inner/outer wall, sparse infill, internal solid infill,
|
||||
top surface, skin, skeleton) > `layer_height` — *"Line width too small"*. `support_line_width` only
|
||||
when the object has support or a raft; `initial_layer_line_width` is never checked.
|
||||
4. every width ≤ 5 × max `nozzle_diameter` — *"Line width too large"*
|
||||
|
||||
Two further rules cover `bridge_line_width` (≤ nozzle diameter; > `layer_height` unless `thick_bridges`
|
||||
and `thick_internal_bridges` are both on). The sweep starts from printer defaults rather than
|
||||
enumerating every process. **A new non-default process gets no dedicated slice coverage in CI.**
|
||||
|
||||
## What CI checks on a process
|
||||
|
||||
Structure, not content: `process_list` name consistency **and** index coverage the other way, two files
|
||||
claiming one process name, the `extruder_clearance_radius` / `extruder_clearance_max_radius` conflict
|
||||
pair, duplicate JSON keys, a file `normalize` would rewrite, and the five `setting_id` rules (the fifth
|
||||
rejects the misspelled key `settings_id`). `compatible_printers` presence is checked for **filaments
|
||||
only**.
|
||||
|
||||
Note the C++ loader derives a missing `setting_id` on the fly, so the validator will not fail a process
|
||||
without one — only `orca_profile_tool.py check` catches it. Running the validator alone gives a false
|
||||
all-clear.
|
||||
|
||||
## Silent failures specific to processes
|
||||
|
||||
- **Unknown or misspelled keys are discarded with no error and no warning.** They ship all over the
|
||||
process tree, both plain typos (`inital_layer_height`, `tree_support_bramch_diameter_angle`,
|
||||
`sparse_infill_patter`) and keys copied from other slicers that Orca never defined.
|
||||
- Keys on the tool's `OBSOLETE_KEYS` list (`adaptive_layer_height`, `overhang_totally_speed`, …) are
|
||||
rejected by `check`'s normalization pass across preset types; `normalize` removes them.
|
||||
The additional per-key obsolete warnings read `filament/` only.
|
||||
- A dangling `compatible_printers` inside an `instantiation: "false"` base is invisible to
|
||||
`check_preset_references`: a base never becomes a `Preset` at all (its config goes into `config_maps`
|
||||
and the loader returns early), so it is in no collection for the check to walk.
|
||||
- Orphan bases that nothing inherits are scattered through the tree — usually the leftover of a
|
||||
half-finished nozzle addition.
|
||||
|
||||
## Adding a quality tier or a nozzle's processes
|
||||
|
||||
1. Choose the layer height and quality label using the vendor's existing ladder.
|
||||
2. If the vendor has per-nozzle bases, add one (`fdm_process_<vendor>_<lh>_nozzle_<n>`) with the layer
|
||||
height, nozzle-appropriate line widths, `initial_layer_print_height` and `ironing_inset`.
|
||||
3. Add the leaf: 7 keys, `compatible_printers` naming the exact printer variant(s).
|
||||
4. Register both in `process_list`, parent first. Bump the version, run the id tool, validate.
|
||||
5. Slice this process explicitly with its intended printer; the sweep gives non-default tiers no
|
||||
dedicated coverage. If it is a printer's `default_print_profile`, verify the exact name and
|
||||
resolved compatibility too — the sweep may fall back or select another compatible process.

|

|
||||
| Not checked by CI | Consequence |

| A misspelled setting key | Setting silently has no effect |

|

|
||||
## 1. Was the vendor `version` bumped?
|
||||
|
||||
For **every** bundle whose folder the diff touches, `resources/profiles/<Vendor>.json` must have its
|
||||
`version` incremented — last component, carrying `.99` into the third component. A library change
|
||||
means bumping `OrcaFilamentLibrary.json`.
|
||||
|
||||
*Why:* nothing in CI checks it, and `PresetUpdater` reinstalls only when `vendor_ver < resource_ver` —
|
||||
without a bump the change reaches neither an upgrading user nor the author's own running app.
|
||||
|
||||
## 2. Was the index rebuilt, and does the diff contain only this change?
|
||||
|
||||
`check` now fails on an unregistered file, on an index `update-index` would reorder, and on a file
|
||||
`normalize` would rewrite — so a PR that skipped them arrives red, and you do not have to spot the
|
||||
omission yourself. Three things are still yours:
|
||||
|
||||
- **The index diff belongs to this change.** `update-index` rewrites whole `*_list` sections. If the
|
||||
bundle had drifted, the author's PR now carries someone else's reordering; ask for it in a separate
|
||||
commit rather than reviewing it inline.
|
||||
- **A deleted selectable preset needs a successor** as in item 4. `update-index` removes its
|
||||
registration; `validate_custom` detects the break only for names covered by released fixtures.
|
||||
- **`normalize` edits content, not just layout.** It drops `version` and `is_custom_defined` from preset
|
||||
files, removes obsolete keys, deletes six print-speed keys from filament profiles, and resolves
|
||||
`extruder_clearance_radius` against `extruder_clearance_max_radius` by keeping the larger.
|
||||
Check that the keys it removed were meant to go.
|
||||
|
||||
Obsolete keys fail `check`'s normalization pass and should be removed with `normalize`.
|
||||
`check` also reports per-key obsolete warnings for filament profiles in the selected vendors.
|
||||
|
||||
*Why:* the index is the loader's only entry point. Out-of-order entries fail with `can not find inherits`
|
||||
and take the whole vendor bundle down; an unindexed file gets reviewed, merged and never loads.
|
||||
|
||||
## 3. Are ids generated, not written?
|
||||
|
||||
No hand-typed or copied `setting_id` / `filament_id`. Instantiated presets have a `setting_id`; bases do
|
||||
not. `check` enforces all of that; what it cannot tell you is whether the identity *should* have moved.
|
||||
|
||||
A rewritten or removed `filament_id` means a product's identity moved — a rename, or an edited
|
||||
`filament_vendor` / `filament_type` — and the old id is not forwarded anywhere. Confirm that was
|
||||
intended, and that a new id is not a rename in disguise.
|
||||
|
||||
*Why:* a duplicate `filament_id` on one printer makes AMS spool matching a coin toss; a copied
|
||||
`setting_id` breaks preset identity. See [ids.md](ids.md).
|
||||
|
||||
## 4. Does anything disappear for existing users?
|
||||
|
||||
A rename, a deletion, or a flip of `"instantiation": "true"` → `"false"` on a shipped preset removes the
|
||||
name from the preset collection. It needs `renamed_from` on a successor — and only one preset may claim a
|
||||
given old name. The claimed old name must **not** still be a live preset; the redirect is inert if it is.
|
||||
|
||||
*Why:* user presets inheriting it die with `can not find parent <name> for config <file>!`; 3MF-embedded
|
||||
presets are dropped with no error at all. Commit `33923464ae` reverted exactly this for Cubicon;
|
||||
`6943b6ddc3` redid it correctly. CI's `validate_custom` catches the shipped-name case — but not an inert
|
||||
`renamed_from`.
|
||||
|
||||
## 5. Is `compatible_printers` right?
|
||||
|
||||
Exact printer **variant** names, non-empty on every instantiated filament outside OrcaFilamentLibrary
|
||||
and written in the preset's own file — golden rule 6, with the flattened-vs-own-key trap in
|
||||
[filament-profiles.md](filament-profiles.md#compatible_printers). Watch for a nozzle-specific variant that
|
||||
inherited or copied the base's full printer list, and for two presets of one product with overlapping
|
||||
lists — duplicate combobox entries and an ambiguous AMS match.
|
||||
|
||||
*Why:* real shipped bugs twice (`b7b3418baf` "showing up everywhere", `ff83aa41ef` duplicate Flashforge
|
||||
entries).
|
||||
|
||||
## 6. Model ↔ variant ↔ process consistency
|
||||
|
||||
- New nozzle size → the model's `nozzle_diameter` list extended, a variant with a matching
|
||||
`printer_variant`, and at least one process listing that variant.
|
||||
- `default_print_profile` is one exact name (not a `;` list), and that process's resolved
|
||||
compatibility list or condition includes this printer.
|
||||
- `default_filament_profile` is an array of names that exist.
|
||||
|
||||
*Why:* an unlisted `printer_variant` is a hard bundle-load failure. Default process selection is
|
||||
weaker: the sweep attempts the named default, then updates compatibility and rejects generic Default
|
||||
fallbacks. Another compatible process can conceal a bad reference, so inspect it even after a pass.
|
||||
|
||||
## 7. Types and spellings
|
||||
|
||||
Every value a string or an array of strings; `filament_type` an array; `instantiation` the string
|
||||
`"true"`/`"false"` — golden rule 7. Check index metadata and model `nozzle_diameter` especially;
|
||||
wrong types there can abort loading for **every** vendor.
|
||||
|
||||
The part only a reviewer can do: check new setting keys against `src/libslic3r/PrintConfig.cpp`. A
|
||||
misspelled key is silently discarded (rule 8), the single most common way a profile edit does nothing
|
||||
while CI stays green.
|
||||
|
||||
## 8. Blast radius of a base edit
|
||||
|
||||
A change to `fdm_*_common.json` reaches every child at once. Ask which presets it touches — several
|
||||
reverts in this repo are exactly this (`41d1b0d3c8`, `dc491166a8`). Also check whether the edited leaf has
|
||||
children of its own: Prusa, Flashforge and Elegoo all chain leaf-inherits-leaf several levels deep.
|
||||
|
||||
## 9. Do the numbers make sense for the nozzle?
|
||||
|
||||
Check resolved widths and layer heights against the nozzle, and flow limits / pressure advance
|
||||
against the actual hardware and material. The patterns in [process-profiles.md](process-profiles.md)
|
||||
are examples, not mandatory values; [filament-profiles.md](filament-profiles.md) explains what to
|
||||
revisit for a nozzle change. A cloned preset's unchanged MVS needs particular scrutiny.
|
||||
|
||||
Settings tuned for real hardware cannot be verified by reading the diff. Say so rather than approving
|
||||
numbers nobody measured.
|
||||
|
||||
## 10. Asset references (not checked anywhere)
|
||||
|
||||
`bed_model`, `bed_texture`, `hotend_model` and `<Model>_cover.png` exist under
|
||||
`resources/profiles/<vendor folder>/`. Broken references already ship; nothing checks them.
|
||||
|
||||
## 11. `default_materials` (checked by CI)
|
||||
|
||||
`check` fails on a `default_materials` / `default_filament_profile` name that resolves to no system
|
||||
filament, so a dangling entry no longer reaches review. Scope the run while working on one vendor:
|
||||
|
||||
```bash
|
||||
python3 scripts/orca_profile_tool.py check --vendor "<Vendor>" # py -3 on Windows
|
||||
```
|
||||
|
||||
## 12. Per-extruder vector lengths (not checked)
|
||||
|
||||
One entry per extruder for the plain per-extruder vectors; the `printer_options_with_variant_1` keys are
|
||||
sized to `printer_extruder_variant` instead. A wrong length is silently padded — repeating the **first**
|
||||
value, not the last — or truncated. The two sizing families and the worked cases are in
|
||||
[machine-profiles.md](machine-profiles.md#multi-extruder-idex-and-tool-changers).
|
||||
|
||||
## 13. Non-default processes get no slice coverage
|
||||
|
||||
`validate_slice` starts from printer defaults; it does not enumerate every process. Slice a new or
|
||||
changed non-default tier explicitly with its intended printer.
|
||||
|
||||
## 14. Housekeeping worth a nit, not a block
|
||||
|
||||
`"from"` other than `"system"` (the preset-bundle loader ignores it, though the CLI's config-file loader
|
||||
rejects anything but `system`/`user`/`User`), `printer_settings_id` copied from another
|
||||
vendor, and a filename that disagrees with the preset's `name` (common; the loader keys off `name`).
|
||||
|
||||
## 15. Cross-platform filenames and paths (not checked)
|
||||
|
||||
Check for Windows-invalid characters, reserved device names, trailing path-component spaces/dots,
|
||||
and case mismatches in `sub_path` or asset paths. See [cross-platform paths](validation.md#cross-platform-paths).

## Reporting the review
|
||||
|
||||
A finding is: **one defect**, its file, what breaks at runtime or in CI, and the fix. Split independent
|
||||
defects into separate findings even when they live in one file — five id problems in one bullet get one
|
||||
fix and four survivors.
|
||||
|
||||
Severity discriminates only if it is earned:
|
||||
|
||||
| Severity | Means |
|
||||
| --- | --- |
|
||||
| blocker | the bundle fails to load, or a preset is unreachable at runtime |
|
||||
| major | CI fails, or existing users lose a preset |
|
||||
| minor | wrong-but-working: dead keys, `from`, naming, redundant overrides |
|
||||
|
||||
Compute every number and id (`orca_profile_tool.py`, a scripted count) or omit it — one invented count
|
||||
makes a reader stop trusting the right ones. Report a command's result only if you ran it.

# Validating profiles
|
||||
|
||||
```bash
|
||||
./scripts/check_profile.sh # everything CI runs
|
||||
./scripts/check_profile.sh --vendor "<Vendor>" # fast loop
|
||||
./scripts/check_profile.sh profile_tool validate_slice # named checks only
|
||||
```
|
||||
|
||||
```bat
|
||||
scripts\check_profile.bat :: the same three, on Windows
|
||||
scripts\check_profile.bat -Vendor "<Vendor>"
|
||||
scripts\check_profile.bat profile_tool validate_slice
|
||||
```
|
||||
|
||||
`check_profile.bat` is a shim around `check_profile.ps1` — same checks, same order, same logs;
|
||||
the flags take PowerShell spellings (`-Vendor`, `-ProfilesDir`, `-Validator`, `-Download`, `-Refresh`,
|
||||
`-WorkDir`, `-LogLevel`) and positional check names are unchanged. `-p`, `-v` and `-l` are aliases, so
|
||||
`-v Elegoo -l 2` reads the same on both platforms. It passes `-ExecutionPolicy Bypass` because a
|
||||
default Windows client refuses to run a checked-out `.ps1` at all. The `.ps1` finds Python itself,
|
||||
probing `py -3`, then `python`, then `python3`; run the tool by hand with `py -3` for the same reason.
|
||||
|
||||
Every check in the run happens even after an earlier one fails; the script exits non-zero if any did, and writes
|
||||
`.test/check_profiles/logs/<check>.log` plus, on failure, `.test/check_profiles/pr_comment.md` — the same
|
||||
report CI posts on the PR. A stale `.test/check_profiles/.lock` after a crash must be removed by hand.
|
||||
|
||||
## The five checks
|
||||
|
||||
| Check | Command it runs | Catches |
|
||||
| --- | --- | --- |
|
||||
| `profile_tool` | `python3 scripts/orca_profile_tool.py check` | index coverage **both ways**, preset-name collisions, files `normalize`/`update-index` would still rewrite, duplicate JSON keys, filament `compatible_printers`, `filament_type` array, conflict keys, id length, **all `setting_id` and `filament_id` rules** |
|
||||
| `validate_system` | `validator -p resources/profiles -l 2` | load errors, missing filament `compatible_printers`, dangling `inherits`/`compatible_*`, duplicate `filament_id` per printer |
|
||||
| `validate_slice` | `validator -p … -s -l 2` | custom G-code expansion, unresolvable printer defaults |
|
||||
| `validate_filament_subtypes` | `validator -p … -l 2 -f` | nothing extra — see below |
|
||||
| `validate_custom` | `validator -p <tree+fixture> -l 2` | a shipped preset name that a past release offered no longer resolving |
|
||||
|
||||
**`-f` is a no-op.** It is declared `po::bool_switch()->default_value(true)`, so the duplicate-`filament_id`
|
||||
check runs whether or not you pass it — `validate_system` already fails on duplicates. The binary's own
|
||||
`--help` ("Off unless this flag is present") does not reflect that default.
|
||||
|
||||
### `validate_custom` — the backward-compatibility gate
|
||||
|
||||
Downloads one fixture archive per past release (v1.9.0 onwards) of *generated mock* user presets —
|
||||
a `<vendor>_<preset>_orca_test` copy of every system preset that
|
||||
release shipped, cut with the validator's own `-g 1` mode — unpacks each over a copy of the current tree
|
||||
and loads it. Each entry holds only `inherits` plus a canned diff, so the one failure it adds over
|
||||
`validate_system` is a shipped preset name disappearing. (The whole current tree sits under each fixture,
|
||||
so every `validate_system` error fails it too.) This is what makes a rename or an
|
||||
`instantiation` flip a CI failure rather than just a user complaint, and the reason `renamed_from` is
|
||||
mandatory.
|
||||
|
||||
### `validate_slice`
|
||||
|
||||
Slices a two-colour cube on every instantiable printer in the tree, sequentially, forcing the prime tower.
|
||||
It selects `default_print_profile` and the first `default_filament_profile`, then updates compatibility;
|
||||
that update can select a different compatible preset. Confirm the intended defaults yourself rather
|
||||
than treating a passing sweep as proof that those exact presets were sliced.
|
||||
A printer fails if it cannot be selected, falls back to a Default preset, throws, produces no g-code, or
|
||||
emits no `CP TOOLCHANGE START`. It cannot be scoped to a filament-only vendor
|
||||
(`No instantiable printer presets found for vendor OrcaFilamentLibrary`); `check_profile.sh` records it
|
||||
as SKIP for a vendor with no `machine/` folder.
|
||||
|
||||
## `orca_profile_tool.py check`
|
||||
|
||||
`check` is one subcommand of the tool that also owns
|
||||
`generate-id`, `normalize`, `trim` and `update-index`; see [ids.md](ids.md) for the writing half.
|
||||
|
||||
| Per vendor | Catches |
|
||||
| --- | --- |
|
||||
| `check_preset_name_uniqueness` | two files in one bundle claiming one type + name — indexed or not |
|
||||
| `check_index_coverage` | a file on disk that no `*_list` references (**an error, not a warning**) |
|
||||
| `check_name_consistency` | an index entry whose `name` disagrees with the file, or whose `sub_path` is missing |
|
||||
| `check_normalized` | a file `normalize` would rewrite, and an index `update-index` would rebuild |
|
||||
| `check_filament_compatible_printers` | an instantiated non-library filament with no `compatible_printers` of its own |
|
||||
| `check_conflict_keys` | `extruder_clearance_radius` alongside `extruder_clearance_max_radius` |
|
||||
| `check_vector_type_keys` | a vector option written as a scalar (`"filament_type": "PLA"`) |
|
||||
| `check_filament_id_length` | a declared `filament_id` longer than 8 characters |
|
||||
| `check_machine_default_materials` | every `default_materials` / `default_filament_profile` name resolves |
|
||||
| `check_obsolete_keys` | per-key warnings for ignored options; **filament files only** |
|
||||
|
||||
Tree-wide, **ignoring `--vendor` entirely**: `check_setting_id_uniqueness` and `check_filament_ids`. So a
|
||||
vendor-scoped run can and does fail on another vendor's files — and it saves seconds, not minutes.
|
||||
|
||||
Unscoped, the per-vendor pass covers every bundle. The only exclusion is the stray `user/` directory
|
||||
(see below); `OrcaFilamentLibrary` is held to the same rules as any vendor, its sole exemption being
|
||||
that a library filament may leave `compatible_printers` empty — exactly what
|
||||
`check_filament_compatible_printers` allows. `check_normalized` covers every bundle with an index.
|
||||
|
||||
Notes that matter:
|
||||
|
||||
- Exit codes: **0** clean, **1** errors found, **2** argparse misuse. Warnings never change the exit code.
|
||||
- A nonexistent `--vendor` is a hard error — `[ERROR] unknown vendor "<V>" in <dir>`, exit 1.
|
||||
- `--vendor ""` means all vendors; `check_profile.sh` relies on that. `--vendor` is repeatable.
|
||||
- A **stray directory** under `resources/profiles/` still gets counted as a vendor by the per-vendor pass
|
||||
and warned about (`No profiles found for vendor: <dir> at …/<dir>.json`, and the "Checked vendors" count
|
||||
goes up by one). The one exception is `user/`, the validator's data dir, which an unscoped `check`
|
||||
skips by name; `--vendor user` still checks and warns about it. Warnings never change the exit code.
|
||||
`normalize`, `trim` and `update-index` ignore strays too — they define a bundle as *a directory with a
|
||||
matching index file*.
|
||||
- Each remedy is printed once for the whole run, not once per file, as a `[WARNING]` under the errors
|
||||
("2 unreferenced file(s) above: delete them, or run … update-index"). Read those lines: they name the
|
||||
command that fixes the batch.
|
||||
- The trailing summary always suggests `normalize`. That is right for the shape errors and misleading for
|
||||
everything else — an id error needs `generate-id`, a dangling `default_materials` needs a human.
|
||||
- `resources/profiles/check_unused_setting_id.py` is a legacy BBL-only diagnostic, not part of
|
||||
profile CI. Use `orca_profile_tool.py check` for current id validation.
|
||||
|
||||
### Obsolete-key diagnostics
|
||||
|
||||
`check` always reports per-key warnings for obsolete options in filament profiles.
|
||||
The normalization check also rejects obsolete keys across preset types; `normalize` removes them.
|
||||
|
||||
### Default-material references
|
||||
|
||||
The materials check finds `default_materials` / `default_filament_profile` entries naming a preset
|
||||
that does not exist. The three authoring errors it surfaces are `,` instead of `;`, wrong case
|
||||
(`@system`), and a whole `;`-joined string stuffed into one array element.
|
||||
|
||||
### `normalize` and `update-index` are part of the check
|
||||
|
||||
`check` fails when either command would still change something, so they are not optional polish — the
|
||||
file that gets reviewed has to be the file that ships. What `normalize` changes is narrow and fixed:
|
||||
adds a missing `type`, deletes a `version` or `is_custom_defined` key from a *preset* file, deletes six
|
||||
print-speed keys from filament profiles (`initial_layer_print_speed`, `outer_wall_speed`,
|
||||
`inner_wall_speed`, `infill_speed`, `top_surface_speed`, `travel_speed`), deletes the
|
||||
obsolete keys in `PrintConfigDef::handle_legacy`'s `ignore` set across preset types, resolves the
|
||||
`extruder_clearance_*` conflict pair by keeping the larger, arrayifies five filament options besides
|
||||
`filament_type`, and hoists `type`, `name`, `renamed_from`, `inherits`, `from`, `setting_id`,
|
||||
`filament_id`, `instantiation` to the front. A file it changes is then rewritten whole — tab-indented,
|
||||
LF, one trailing newline, keys reordered.
|
||||
|
||||
**Set `type` explicitly when authoring.** For a file in `machine/` without it, normalization guesses
|
||||
`machine` only if its name contains `nozzle`, otherwise `machine_model`. That heuristic cannot
|
||||
reliably classify shared machine bases or unusually named variants.
|
||||
|
||||
The Python obsolete-key set is checked against the C++ source by a unit test. Active options
|
||||
and legacy aliases that the loader migrates (such as `extruder_type` and
|
||||
`extruder_clearance_max_radius`) are preserved.
|
||||
|
||||
Two things it therefore does **not** enforce:
|
||||
|
||||
- **Formatting and key order on their own.** A file with none of those problems is skipped entirely, so
|
||||
4-space indent, a missing trailing newline, and a file that leads with `compatible_printers` all pass
|
||||
`check`. They stay latent until something else trips `normalize` and the whole file reformats inside an
|
||||
unrelated diff. (`normalize --force` rewrites every file, which is not something to run on a shipped
|
||||
bundle.)
|
||||
- **A misspelled setting key.** `inital_layer_height` and `sparse_infill_densiti` pass `check` cleanly.
|
||||
Verify new keys against `PrintConfig.cpp` and `PrintConfigDef::handle_legacy`.
|
||||
|
||||
## The validator binary
|
||||
|
||||
Built from `src/dev-utils/OrcaSlicer_profile_validator.cpp` (`-DORCA_TOOLS=ON`).
|
||||
Both scripts find a local build under `build*/` — `check_profile.sh` tries Release, RelWithDebInfo, then
|
||||
Debug, and `check_profile.ps1` adds MinSizeRel — else they download the nightly into
|
||||
`.test/check_profiles/validator`. Pass `--download` / `-Download` to match CI exactly, since a stale
|
||||
local build is used silently. Windows looks for `OrcaSlicer_profile_validator.exe`.
|
||||
|
||||
If your build lives somewhere else entirely, point at it with `--validator` / `-Validator`, or set
|
||||
`ORCA_PROFILE_VALIDATOR` (`$env:ORCA_PROFILE_VALIDATOR` in PowerShell).
|
||||
|
||||
| Flag | Meaning |
|
||||
| --- | --- |
|
||||
| `-p <dir>` | profile tree (also becomes the data dir) |
|
||||
| `-l <n>` | log level; CI uses 2 |
|
||||
| `-v <Vendor>` | load only that vendor **plus** OrcaFilamentLibrary |
|
||||
| `-s` | slice sweep |
|
||||
| `-f` | no-op (see above) |
|
||||
| `-g 1` | regenerate user-preset fixtures; takes a value, and wipes the user preset dir first |
|
||||
|
||||
On ARM64 Linux the nightly is x86-64 only — the script warns and downloads anyway, producing a binary
|
||||
that will not run. Build it locally instead.
|
||||
|
||||
Running the validator directly uses the profile tree as its data directory and can create `user/`
|
||||
there. Prefer the wrappers, which stash existing user presets and restore them afterward. After a
|
||||
direct run, inspect `user/` and remove only empty directories created by that run; fixtures or
|
||||
pre-existing user files may be present.
|
||||
|
||||
## Checking a copy of the tree
|
||||
|
||||
Use `--profiles DIR` on the Python tool and `-p DIR` on the validator. The wrappers' `--profiles` /
|
||||
`-ProfilesDir` passes the tree to both, so one run validates a copy fully:
|
||||
|
||||
```bash
|
||||
./scripts/check_profile.sh --profiles "<tree>"
|
||||
```
|
||||
|
||||
On Windows use `scripts\check_profile.bat -ProfilesDir "<tree>"`.
|
||||
|
||||
## Testing in the app
|
||||
|
||||
Editing this checkout's `resources/profiles` does not update a separately installed application.
|
||||
Test with a build using the edited resources and a bumped bundle version; the updater installs newer
|
||||
bundles under `<data_dir>/system/`, and the preset cache also depends on the bundle version.
|
||||
Use Help ▸ Show Configuration Folder to locate the active data directory:
|
||||
|
||||
| Platform | Default data directory |
|
||||
| --- | --- |
|
||||
| macOS | `~/Library/Application Support/OrcaSlicer` |
|
||||
| Linux | `$XDG_CONFIG_HOME/OrcaSlicer`, or `~/.config/OrcaSlicer` when unset |
|
||||
| Windows | `%APPDATA%\OrcaSlicer` |
|
||||
|
||||
A portable `data_dir` next to the executable takes precedence. Use a separate test configuration
|
||||
for a clean-install check; preserve the normal configuration and user presets.
|
||||
|
||||
## Cross-platform paths
|
||||
|
||||
Match the exact case of each `sub_path` and asset filename; Linux filesystems commonly distinguish
|
||||
case even when a macOS or Windows checkout does not. Preset-name references are case-sensitive
|
||||
on every platform. Avoid Windows-invalid characters (`< > : " | ? *`), reserved device names
|
||||
such as `CON` / `NUL` (including with extensions), and trailing spaces or dots in path components.
|
||||
Keep stems tidy too, but a space immediately before `.json` is not a trailing path-component space.
|
||||

||||

## CI
|
||||
|
||||
`.github/workflows/check_profiles.yml`, job **"Check profiles"**, on `pull_request` into `main` or
|
||||
`release/*`, paths `resources/profiles/**`, `resources/printers/**`, `scripts/**` and the workflow itself.
|
||||
There is no push trigger — a direct push to main runs no profile validation.
|
||||
|
||||
The job opens with `python3 -m unittest discover -s scripts/tests -t scripts`, the tool's own unit
|
||||
tests. That step is deliberately **not** `continue-on-error`: a broken tool makes everything it then says
|
||||
about the profiles worthless. Every check after it is `continue-on-error` with a final gate, so one run
|
||||
reports all five results. On failure a second workflow posts or replaces a single PR comment marked
|
||||
`<!-- profile-validation-comment -->`, with each failing log truncated to 30 KB; it deletes the comment
|
||||
once the run is green.
|
||||

# The vendor bundle and the loader
|
||||
|
||||
A bundle is `resources/profiles/<Vendor>.json` (the index) plus `resources/profiles/<Vendor>/`.
|
||||
The **vendor id is the filename stem**, not the `name` inside — several differ (`BBL.json` is named
|
||||
"Bambulab"). Asset paths and the `setting_id` formula use the id; the `validate_custom` fixture prefix
|
||||
uses the `name`.
|
||||
|
||||
## The index
|
||||
|
||||
```json
|
||||
{
|
||||
"name": "Phrozen",
|
||||
"version": "02.04.00.03",
|
||||
"force_update": "0",
|
||||
"description": "Phrozen configurations",
|
||||
"machine_model_list": [ { "name": "...", "sub_path": "machine/....json" } ],
|
||||
"machine_list": [ ... ],
|
||||
"process_list": [ ... ],
|
||||
"filament_list": [ ... ]
|
||||
}
|
||||
```
|
||||
|
||||
The loader reads `name`, `version`, `url` and the four `*_list` arrays.
|
||||
`description` is only logged. `force_update` is read by `PresetUpdater`, never by the loader.
|
||||
`sub_path` is relative to the **vendor folder**.
|
||||
|
||||
| List | Holds |
|
||||
| --- | --- |
|
||||
| `machine_model_list` | `machine_model` records (the printer product) |
|
||||
| `machine_list` | printer variants **and** shared machine bases |
|
||||
| `process_list` | selectable processes **and** shared process bases |
|
||||
| `filament_list` | selectable filaments **and** shared filament bases |
|
||||
|
||||
### Three registration rules
|
||||
|
||||
1. **Everything is registered, bases included.** Every preset file on disk has exactly one entry in the
|
||||
matching list, and no unindexed preset file is left in the tree.
|
||||
2. **Parents before children.** `inherits` resolves against a per-kind map filled as the list is walked
|
||||
(`configs.clear()` then process, filaments, printers). A parent listed after its child produces
|
||||
`can not find inherits <parent> for <child>` and the bundle is discarded.
|
||||
3. **The index entry's `name` must equal the `name` inside the sub_path file.** `check_name_consistency`
|
||||
walks the index looking for the files; `check_index_coverage` walks the files looking for them in the
|
||||
index. The `renamed_from` escape hatch `check_name_consistency`'s docstring promises is commented out.
|
||||
|
||||
All three are `check` errors now, and `update-index` writes an index that satisfies all three from the
|
||||
files on disk — including the parents-first ordering, by topological sort. Hand-editing the index is
|
||||
fine for a one-line addition, but the committed result must equal what `update-index` writes, because
|
||||
`check` compares them.
|
||||
|
||||
The loader itself reports none of this: an unregistered file, or an entry with a typo'd key
|
||||
(`"subpath"`), is silently dropped. (A typo'd `sub_path` is a `check` error naming the entry.)
|
||||
|
||||
`BBL/cli_config.json` and `BBL/filament/filaments_color_codes.json` are auxiliary data loaded by path,
|
||||
not presets. The tool's `NON_PROFILE_FILES` excludes these basenames from preset maintenance.
|
||||
|
||||
## `version`
|
||||
|
||||
Parsed by a four-component Semver where the 4th is folded in as `patch = patch*100 + value`. Write it
|
||||
zero-padded, `MM.mm.pp.bb`; a couple of bundles drop a component or the padding, but do not imitate them.
|
||||
|
||||
- **Bump the version for every bundle the PR touches.** `PresetUpdater` installs bundled resources
|
||||
only when their version is newer than the installed version; the `.opc` preset cache is also
|
||||
versioned. Nothing in profile CI checks the bump.
|
||||
- **Keep the last component ≤ 99.** `02.04.00.100` and `02.04.01.00` both parse to `2.4.100`. A bundle
|
||||
that reaches `.99` carries into the third component (`02.03.02.99` → `02.03.03.00`).
|
||||
- An **absent** version is worse than a stale one: the validator still passes, but `Semver::valid()`
|
||||
excludes `0.0.0`, so the vendor is dropped from the configuration wizard entirely and the preset cache
|
||||
is disabled for it. An *unparseable* version is not silent — it throws and discards the whole bundle
|
||||
(see the failure table below).
|
||||
|
||||
## Common preset keys
|
||||
|
||||
| Key | Value |
|
||||
| --- | --- |
|
||||
| `type` | `machine_model` / `machine` / `process` / `filament` |
|
||||
| `name` | the preset name; the filename is *not* authoritative |
|
||||
| `inherits` | the parent's exact `name` — no path, no `.json` |
|
||||
| `instantiation` | the **string** `"true"` (selectable) or `"false"` (base) |
|
||||
| `from` | `"system"` by convention; the vendor loader never reads it |
|
||||
| `setting_id` | required on instantiated presets, forbidden on bases — generated |
|
||||
| `renamed_from` | `;`-separated list of old names this preset supersedes |
|
||||
|
||||
These are config-preset keys; `machine_model` records have their own
|
||||
[schema](machine-profiles.md#a-machine_model-is-not-a-config-preset). Keep `from` as `"system"`
|
||||
for shipped presets. The vendor loader ignores it, but the CLI config-file loader accepts only
|
||||
`system`, `user` or `User` and handles their inheritance differently.
|
||||
|
||||
`instantiation` is the one metadata key that is hard-gated: a missing key or any value other than the
|
||||
strings `"true"`/`"false"` is an error (`Missing instantiation attribute for <name>`). A JSON boolean
|
||||
`true` fails harder — it throws inside `load_from_json` and takes the **whole vendor bundle** down.
|
||||
|
||||
### `inherits`
|
||||
|
||||
Resolution is an exact-name lookup **within the same bundle**, plus one exception: filaments may inherit
|
||||
from `OrcaFilamentLibrary`, which is loaded first and becomes the base bundle. Vendor-to-vendor
|
||||
inheritance always fails. You can inherit from an instantiated preset as well as from a base; it is
|
||||
common.
|
||||
|
||||
### `renamed_from`
|
||||
|
||||
One JSON string, `;`-separated for several old names.
|
||||
|
||||
- Write `"A;B"`, never `"A ; B"` — an unquoted item keeps its trailing space and can never match.
|
||||
- When `renamed_from` is **absent** and the name contains `@`, the loader auto-adds the `@`-removed form
|
||||
(`X @Y` → `X Y`) as a rename alias. Declaring an explicit `renamed_from` **suppresses** that, so a
|
||||
preset that needs both the `@`-removed form and a real old name must list both. No shipped profile
|
||||
currently does, which means any preset that gained a `renamed_from` quietly lost its `X Y` alias.
|
||||
- It rescues names stored **outside** the tree: user presets and 3MF projects. It does **not** rescue
|
||||
in-tree `inherits` (exact lookup), it does **not** satisfy `check_name_consistency`, the validator
|
||||
reports an in-tree reference that only resolves through it (`references renamed compatible_printers
|
||||
"OLD" (now "NEW")`), and `machine_model` records never read it at all.
|
||||
- Only one preset may claim a given old name — two that do is a counted error
|
||||
(`… was marked as renamed from "Y" … as well`). But the redirect is **inert while a live preset still
|
||||
carries that name**, and nothing checks *that*; Z-Bolt ships a folder of such dead entries.
|
||||
|
||||
## Failure modes, ranked by blast radius
|
||||
|
||||
| Scope | Cause |
|
||||
| --- | --- |
|
||||
| **All vendors, zero system profiles** | a non-string `version`, `name` or `url` at the top level of a vendor index (`"version": 2`), or non-string `nozzle_diameter` on a model — `nlohmann::type_error` escapes the per-vendor `std::runtime_error` catch |
|
||||
| **The whole vendor bundle** | unparseable `version`; index JSON parse error; a `sub_path` file missing or unparseable; unresolvable `inherits`; duplicate preset name within the vendor; empty/unknown `printer_model` or `printer_variant`; a filament resolving no `filament_id` |
|
||||
| **One preset** | `instantiation` missing or a wrong string; keys belonging to another preset type (`contains incorrect keys: …, which were removed`); a non-string inside a `*_list` entry (`invalid value type for <key>`) |
|
||||
| **Logged, not counted** | a raw JSON number in a preset — `invalid json type for <key>`, the value is dropped and the exit code stays 0 |
|
||||
| **Nothing reported by the loader** | unregistered file; misspelled setting key; missing bed/hotend asset. Only the first of those is a `check` error; the other two reach users |
|
||||
|
||||
Deleting a file the index still lists surfaces as a *parse error* on line 1, not "file not found" — the
|
||||
loader `ifstream`s the missing path and nlohmann reports `unexpected end of input`.
|
||||
|
||||
Preset names are a **single global namespace across every vendor**: a duplicate within one vendor is a
|
||||
hard bundle failure, a duplicate across vendors is reported as `Found duplicated preset: <name> in
|
||||
vendor: <vendor>` and still counts as an error. `check_preset_name_uniqueness` catches the within-bundle
|
||||
case earlier and more precisely — including an *unindexed* twin, which is one `sub_path` edit away from
|
||||
silently becoming the parent every child resolves to (`std::map::emplace` keeps the first insertion, so
|
||||
index order decides). Base names, by contrast, repeat across bundles by design: `fdm_process_common`
|
||||
exists in nearly all of them.
|
||||
|
||||
## Starting a whole new vendor bundle
|
||||
|
||||
Nothing generates one; copy the smallest bundle that resembles the hardware. **`Voxelab` or `M3D`** are
|
||||
the minimal shape — a shared machine base, the model, one variant, a shared process base, two
|
||||
processes, and an empty `filament_list` that takes the library generics. Do *not* start from `Phrozen`:
|
||||
it carries local `fdm_filament_*` copies that have drifted from the library, and a filament preset that
|
||||
restates most of its parent — the style this skill advises against.
|
||||
|
||||
Write the machine files **last**, so you only visit them once:
|
||||
|
||||
1. **Choose the names first** — model, variant(s), process(es). Everything else references them.
|
||||
2. `resources/profiles/<Vendor>.json`: `name`, `version` (`01.00.00.00`), `force_update: "0"`,
|
||||
`description`, and all four `*_list` arrays (an empty `filament_list` is fine).
|
||||
3. The shared bases — `<Vendor>/machine/fdm_machine_common.json` and
|
||||
`<Vendor>/process/fdm_process_common.json`, both `"instantiation": "false"` with no `setting_id`.
|
||||
For a Klipper printer add your own `<Vendor>/machine/fdm_klipper_common.json` inheriting the machine
|
||||
base; there is no shared one, because a `machine` preset can only inherit inside its own bundle.
|
||||
4. One selectable process per variant, each naming its variant in `compatible_printers`.
|
||||
5. Bed assets and `<Model>_cover.png`, all directly in `<Vendor>/`. None of them is needed for the
|
||||
bundle to load, and nothing in CI checks them — but the bed files are inert unless the `machine_model`
|
||||
names them in `bed_model` / `bed_texture`, and the cover is found by convention as
|
||||
`<the name you gave the model in machine_model_list>_cover.png`.
|
||||
6. The `machine_model` record and the `machine` variants, now that every value they reference exists —
|
||||
the minimum key sets and the `default_*` shapes are in
|
||||
[machine-profiles.md](machine-profiles.md#the-machine-variant).
|
||||
7. Run the tool and validate — follow
|
||||
[Creating or modifying a profile](../SKILL.md#creating-or-modifying-a-profile). `generate-id` is not
|
||||
optional for a new bundle: the validator loads presets that have no `setting_id`, but `check` fails
|
||||
every one of them. `update-index` will fill the four `*_list` arrays for you once the files exist, so
|
||||
step 2 only needs the bundle metadata to be right.
|
||||
|
||||
## `resources/profiles_template/`
|
||||
|
||||
A separate tree (`Template.json` + `Template/`) holding filament and process templates. It is **not** a
|
||||
scaffold for shipped profiles — `CreatePresetsDialog.cpp` reads it for the in-app "create a custom
|
||||
printer/filament" wizard, so editing it changes what users get when they create a custom preset.
|
||||
`check_profile.sh`'s validator checks default to `resources/profiles` (redirectable with `-p`), and so
|
||||
does `orca_profile_tool.py` (redirectable with `--profiles`);
|
||||
neither covers this tree.

# Orca-CAD vs Onshape — capability gap analysis
|
||||
|
||||
Generated 2026-07-22 by enumerating the source, not from recollection:
|
||||
`CadFeatureType` and `add_*` in `src/libslic3r/CAD/CadDocument.hpp`, `Tool` in
|
||||
`src/slic3r/GUI/CAD/DesignPanel.hpp`, `Mode` in `src/slic3r/GUI/CAD/DesignSketchTool.hpp`,
|
||||
`SketchConstraintType` + `SketchEntity::Type` in `src/libslic3r/CAD/SketchEngine.hpp`,
|
||||
and the JSON-RPC dispatch in `src/slic3r/GUI/CAD/McpControl.cpp`.
|
||||
|
||||
**Scope note.** Onshape is a cloud PLM platform; Orca is a Design tab inside a
|
||||
slicer. A large share of Onshape's surface (release management, branching, real-time
|
||||
collaboration, FEA, rendering, PDM) is out of scope by construction and is listed
|
||||
separately at the bottom rather than counted as a "missing tool".
|
||||
|
||||
---
|
||||
|
||||
## 1. What Orca already has
|
||||
|
||||
### 2D sketcher — near parity with Onshape
|
||||
This is the strongest area. Very little is missing.
|
||||
|
||||
| Category | Orca |
|
||||
|---|---|
|
||||
| Entities | Line, Polyline, Arc (3-point / tangent / center), Circle (center / 2-point / 3-point), Point, Ellipse, Elliptical arc, B-spline |
|
||||
| Shapes | Rectangle (corner / center / oblique / rounded), Slot, Arc-slot, Polygon |
|
||||
| Edit ops | Fillet, Chamfer, Offset, Mirror, Trim, Extend |
|
||||
| Transforms | Move, Rotate, Scale, Linear array, Polar array |
|
||||
| Constraints (19) | Fix, Coincident, Horizontal, Vertical, Distance, LockX, LockY, EqualLength, Parallel, Perpendicular, Concentric, Tangent, Midpoint, Symmetric, Angle, Radius, Diameter, PointOnLine, PointOnObject |
|
||||
| Dimensions | Length, Diameter, Radius, Angle, Distance, Distance-to-line |
|
||||
|
||||
Solver: vendored SolveSpace (`libslvs`, GPL-3.0) — the same solver lineage as a
|
||||
commercial-grade sketcher.
|
||||
|
||||
### Part features
|
||||
|
||||
| Present | Notes |
|
||||
|---|---|
|
||||
| Extrude | + up-to-face / up-to-point, taper, flip |
|
||||
| Revolve | angle-arc gizmo |
|
||||
| Sweep | along a path |
|
||||
| Loft | multi-profile |
|
||||
| Fillet / Chamfer | edge-level |
|
||||
| Draft | face taper |
|
||||
| Shell | wall thickness + open face |
|
||||
| Hole / Thread | face-aware placement |
|
||||
| Pattern | linear + circular |
|
||||
| Boolean | New / Add / Cut / Intersect, with face-mating |
|
||||
| Cut | plane-based, signed offset |
|
||||
| Datum plane | offset / 2-face / 2-edge derived |
|
||||
| Import | STEP (B-rep) + mesh→B-rep (native mesh2step port) |
|
||||
| Export | STEP (native B-rep, not tessellated) |
|
||||
| Multi-body | + per-body colour |
|
||||
| Section view | with flip |
|
||||
| Undo/redo | full feature-tree recompute |
|
||||
| 3MF persistence | parametric recipe survives save/load |
|
||||
|
||||
### Automation
|
||||
9 MCP JSON-RPC methods: `describe_tools`, `describe_scene`, `query_topology`,
|
||||
`measure`, `slice_body`, `import_step`, `import_mesh`, `validate_against`, plus
|
||||
build actions `extrude`, `revolve`, `fillet`, `chamfer`, `hole`, `boolean`, `pattern`.
|
||||
Onshape's equivalent is its REST API + FeatureScript.
|
||||
|
||||

|
||||
|
||||
## 2. Missing tools — ranked by impact
|
||||
|
||||
### Tier 1 — structural absences (whole subsystems)
|
||||
|
||||
**1. Assemblies and mates.** Entirely absent. No assembly document, no mate
|
||||
connectors, no fastened / revolute / slider / cylindrical / planar / ball / pin-slot
|
||||
mates, no assembly patterns, no interference detection, no exploded views.
|
||||
`bool_target_face` / `bool_tool_face` do face-to-face *mating* for a boolean, which
|
||||
is geometric alignment, not a kinematic joint.
|
||||
*Impact:* multi-part products cannot be positioned or validated as a mechanism.
|
||||
*Note:* an MCP-side `align_instance_to_face` / `create_*_mate` vocabulary already
|
||||
exists on the Onshape bridge in this workspace, so the target semantics are known.
|
||||
|
||||
**2. Drawings / 2D documentation.** Absent. No drawing sheets, dimensioned views,
|
||||
section/detail views, GD&T, title blocks, or BOM.
|
||||
*Impact:* nothing manufacturable-by-a-third-party leaves the tool. For 3D printing
|
||||
this matters less than for machining, which is the honest reason it is Tier 1 by
|
||||
CAD convention but arguably Tier 3 for this product.
|
||||
|
||||
**3. Variables, equations, configurations.** Absent — no `add_variable`, no
|
||||
expression evaluation, no configuration table. Every dimension is a literal double.
|
||||
*Impact:* this is the biggest *parametric* gap. "Make this bracket for an M4 vs M5
|
||||
bolt" requires re-editing every dependent feature by hand. Onshape's Variable
|
||||
Studio + configurations are a core differentiator, and this is the cheapest Tier 1
|
||||
item to close for the size of the payoff.
|
||||
|
||||
**4. Surface modelling.** Absent. No surface extrude/revolve/loft/sweep, no fill,
|
||||
knit, trim/extend surface, offset surface, or thicken. Orca is solid-only.
|
||||
*Impact:* organic/complex shapes and repair of imported junk geometry are impossible.
|
||||
OCCT already provides all of it (`TKOffset`, `TKBRep`), so the kernel is not the
|
||||
blocker — only UI and feature plumbing.
|
||||
|
||||
**5. Sheet metal.** Absent. No flange, bend, tab, relief, or flat-pattern unfold.
|
||||
*Impact:* arguably out of scope for an FDM slicer; listed for completeness.
|
||||
|
||||
### Tier 2 — individual features with clear demand
|
||||
|
||||
| Missing | Why it matters | Cheap? |
|
||||
|---|---|---|
|
||||
| **Mirror body** (part-level) | Sketch mirror exists; mirroring a *solid* about a plane does not. Extremely common. | Yes — OCCT `gp_Trsf` mirror + fuse |
|
||||
| **Helix / spiral curve** | No helix ⇒ no springs, no custom threads, no spiral vase geometry. Sweep exists but has no helical path to sweep along. | Yes |
|
||||
| **Move / rotate body as a real feature** | `m_body_xform` exists but is **display-only** (memory #1655) — it never enters the B-rep. Export/boolean see the original position. | Medium |
|
||||
| **Split body** | Cut removes material; splitting one body into two independently-usable bodies is absent. Very relevant for print-in-parts. | Medium |
|
||||
| **Thicken** | Solid from a surface/face offset. | Needs surfaces |
|
||||
| **Rib** | Standard structural feature. | Medium |
|
||||
| **Delete face / move face / replace face** | Direct/dumb-solid editing — the main tool for fixing imported STEP. Given Orca imports STEP *and* meshes, its absence is felt. | Medium |
|
||||
| **Datum axis, coordinate system** | Only datum *planes* exist. Axes are needed for revolve/pattern references. | Yes |
|
||||
| **Mass properties** | `GeometryEngine` computes a volume internally, but there is no volume/mass/COM/inertia readout. For print cost/time estimation this is nearly free to expose. | Yes — trivial |
|
||||
| **Measure tool in the GUI** | `measure` exists over MCP but there is no interactive measure in the UI. | Yes |
|
||||
| **Hole standards library** | Hole exists, but no counterbore/countersink/tapped standards (ISO/ANSI) with callouts. | Medium |
|
||||
| **Project / convert edges into a sketch** | Cannot reference existing solid edges as sketch geometry ("Use" in SolidWorks). A significant sketcher gap given everything else is present. | Medium |
|
||||
| **Construction geometry** | Could not confirm a construction/reference-line flag on sketch entities. | Yes if absent |
|
||||
| **Curve tools** | Projected curve, bridging curve, composite curve, 3D fit spline. | Medium |
|
||||
| **Pattern on curve / pattern faces** | Pattern is linear + circular of whole bodies only; no curve-driven pattern, no feature/face pattern. | Medium |
|
||||
| **Wrap / emboss** | Text or sketch wrapped onto a curved face. | Hard |
|
||||
| **Enclose** | Solid from bounded void regions. | Medium |
|
||||
|
||||
### Tier 3 — platform capabilities (out of scope by construction)
|
||||
|
||||
Version control with branching/merging, release management, real-time multi-user
|
||||
collaboration, cloud PDM, FeatureScript custom-feature authoring, simulation/FEA,
|
||||
photorealistic rendering, app store/integrations. These are Onshape-the-platform,
|
||||
not Onshape-the-modeller. Not defects in Orca.
|
||||
|
||||

|
||||
|
||||
## 3. Recommended priority
|
||||
|
||||
If the goal is "credible parametric CAD inside a slicer", the ordering that buys
|
||||
the most capability per unit of work:
|
||||
|
||||
1. **Variables + expressions** — unlocks genuine parametric reuse; no new kernel work.
|
||||
2. **Mass properties + GUI measure** — nearly free, immediately useful for printing.
|
||||
3. **Mirror body, datum axis, helix** — small, self-contained, high-frequency features.
|
||||
4. **Promote move/rotate body from display-only to a real B-rep feature** — closes a
|
||||
correctness gap, not just a missing tool (exports currently disagree with the view).
|
||||
5. **Split body** — high value for print-in-parts workflows.
|
||||
6. **Project edges into sketch** — the sketcher's most conspicuous hole.
|
||||
7. **Surface modelling** — large, but OCCT already ships the algorithms.
|
||||
8. **Assemblies** — largest effort; only worth it if Orca targets multi-part products.
|
||||
|
||||
Deliberately last: drawings and sheet metal — high cost, low relevance to an
|
||||
FDM-oriented tool.
|
||||
|
||||
---
|
||||
|
||||
## 4. Honest summary
|
||||
|
||||
Orca's **sketcher is at or near Onshape parity**, and its **solid feature set
|
||||
covers the mainstream modelling path** (sketch → extrude/revolve/sweep/loft →
|
||||
dress-up → boolean/pattern). What is absent is *breadth*: assemblies, surfaces,
|
||||
sheet metal, drawings, and — most importantly for a tool calling itself parametric —
|
||||
**variables and configurations**.
|
||||
|
||||
The single most defensible criticism is #3: without variables, the feature tree is
|
||||
parametric in *structure* but not in *value*, so the promise of "change one number
|
||||
and the model updates" is only half delivered.

# Dependency weight of the Design/CAD subsystem
|
||||
|
||||
What the Design tab actually costs a maintainer who merges it. Written to be checkable:
|
||||
every number below is reproducible with the command that produced it, and the places where
|
||||
a number is still missing say so instead of guessing.
|
||||
|
||||
Measured on Linux x86_64, OCCT V7_6_0, in the `snapmaker-deps` build image.
|
||||
|
||||
## Summary
|
||||
|
||||
| | Cost |
|
||||
|---|---|
|
||||
| New third-party dependencies | **none** |
|
||||
| OCCT build flag | `BUILD_MODULE_ModelingAlgorithms=ON` |
|
||||
| Extra OCCT toolkits *built* | 3 (TKFillet, TKOffset, TKFeat) |
|
||||
| Extra OCCT toolkits *linked* | 2 (TKFillet, TKOffset) |
|
||||
| Vendored code | `src/libslic3r/slvs`, 9,339 lines, 380 KiB, GPLv3 |
|
||||
| Own object code | 6.79 MiB unstripped `.o` (7.13 MiB with the solver) |
|
||||
|
||||
OCCT is **already** an upstream dependency — Orca uses it for STEP import. The Design tab
|
||||
does not add a library; it turns on one more OCCT module.
|
||||
|
||||
## The OCCT module flag
|
||||
|
||||
`deps/OCCT/OCCT.cmake` gates the module on `SLIC3R_CAD`:
|
||||
|
||||
```cmake
|
||||
-DBUILD_MODULE_ModelingAlgorithms=${SLIC3R_CAD} # was hard-coded OFF
|
||||
```
|
||||
|
||||
With `SLIC3R_CAD=OFF` the deps prefix matches upstream exactly.
|
||||
|
||||
`ModelingAlgorithms` contains 12 toolkits, but **most were already being built**, because
|
||||
`DataExchange` — the STEP path upstream already ships — depends on them. The honest delta is
|
||||
only the toolkits that DataExchange's dependency closure does *not* reach:
|
||||
|
||||
```
|
||||
ModelingAlgorithms = TKGeomAlgo TKTopAlgo TKPrim TKBO TKBool TKHLR
|
||||
TKFillet TKOffset TKFeat TKMesh TKXMesh TKShHealing
|
||||
|
||||
already required by DataExchange: TKBO TKBool TKGeomAlgo TKHLR TKMesh
|
||||
TKPrim TKShHealing TKTopAlgo
|
||||
true delta: TKFeat TKFillet TKOffset TKXMesh
|
||||
```
|
||||
|
||||
Reproduce by walking `adm/MODULES` and each toolkit's `src/<TK>/EXTERNLIB` in the OCCT
|
||||
source tree.
|
||||
|
||||
### Sizes of the delta toolkits
|
||||
|
||||
Static archives in the deps prefix. These are *build artifacts*, not shipped bytes — a
|
||||
static link pulls in only the objects it references:
|
||||
|
||||
| Toolkit | Archive | Referenced by the Design tab? |
|
||||
|---|---|---|
|
||||
| TKFillet | 7.40 MiB | yes — `BRepFilletAPI` |
|
||||
| TKOffset | 5.38 MiB | yes — `BRepOffsetAPI`, `BRepOffset_` |
|
||||
| TKFeat | 4.42 MiB | **no** |
|
||||
| TKXMesh | — | not produced at all |
|
||||
|
||||
TKFeat is worth calling out: nothing in the Design tab references it, and it is absent from
|
||||
the `TKFillet`/`TKOffset` dependency closure, so it is built for nothing. OCCT's module flag
|
||||
is all-or-nothing per module, which is why it comes along. It costs build time and zero
|
||||
shipped bytes on any platform that links OCCT statically.
|
||||
|
||||
**A correction to the record.** The comment in `deps/OCCT/OCCT.cmake` and the earlier
|
||||
summary both said the delta was "TKFillet + TKOffset — 3.77 MiB, Windows only". The toolkit
|
||||
list was incomplete: TKFeat is built too. The 3.77 MiB figure covers 2 of the 3 built
|
||||
toolkits and has not been re-derived here — see the gap below.
|
||||
|
||||
## What is not measured yet
|
||||
|
||||
Two numbers a maintainer may reasonably ask for are **not** in this document, because
|
||||
producing them honestly needs a build this machine cannot do:
|
||||
|
||||
1. **Windows DLL delta.** OCCT builds shared on Windows, so the shipped cost there is real
|
||||
DLL bytes rather than linker-selected objects. That needs a Windows build to size —
|
||||
tracked as the cross-platform build proof (`gix`).
|
||||
2. **Clean-build time delta.** Measuring it means building the deps prefix twice, with the
|
||||
flag ON and OFF, on the same machine. The incremental figures from day-to-day work do not
|
||||
answer the question and are not offered as if they did.
|
||||
|
||||
Do not quote a number for either until it has been measured.
|
||||
|
||||
## Vendored solver
|
||||
|
||||
`src/libslic3r/slvs` — the 2D sketch constraint solver extracted from SolveSpace.
|
||||
|
||||
- 19 files: 8 `.cpp`, 11 `.h`, plus `LICENSE`
|
||||
- 9,339 lines, 380 KiB of source, 0.34 MiB of object code
|
||||
- **GPLv3**, `LICENSE` preserved verbatim in the vendored directory
|
||||
|
||||
The fork is **AGPLv3**. GPLv3 code combines into an AGPLv3 work without difficulty: AGPLv3
|
||||
§13 provides explicit compatibility in that direction. No licence question to resolve.
|
||||
|
||||
It is live code, not a carried corpse — `SketchSolver.cpp` is its only consumer and drives
|
||||
every sketch constraint in the Design tab.
|
||||
|
||||
## Own code
|
||||
|
||||
Object sizes from the release build (unstripped, so these include debug information and
|
||||
overstate the shipped contribution):
|
||||
|
||||
| Object | Size |
|
||||
|---|---|
|
||||
| DesignPanel.o | 2.22 MiB |
|
||||
| McpControl.o | 1.69 MiB |

| slvs (all objects) | 0.34 MiB |
|
||||
| **total** | **7.13 MiB** |

# Orca-CAD — UX guidelines and design charter
|
||||
|
||||
Status: proposed, v1. Owner: design working group. Applies to the Design tab —
|
||||
the parametric CAD environment inside OrcaSlicer.
|
||||
|
||||
This document is a **review instrument**, not an essay. Sections 3–9 are written
|
||||
so that a reviewer can hold a pull request against them and get a yes or a no.
|
||||
If a rule here cannot be failed, it is badly written and should be rewritten.
|
||||
|
||||
---
|
||||
|
||||
## 1. Why this exists
|
||||
|
||||
A CAD tool acquires its interface by accretion. Every feature arrives needing
|
||||
"just one more field", the side panel is the cheapest place to put it, and after
|
||||
forty features the product is FreeCAD: complete, respected, and abandoned by
|
||||
almost everyone who opens it once. That end state is not a failure of any single
|
||||
decision. It is the sum of forty locally reasonable ones taken without a written
|
||||
rule to violate.
|
||||
|
||||
So we write the rule down first, and we make additions argue against it.
|
||||
|
||||
## 2. Product thesis
|
||||
|
||||
**Orca-CAD is a modelling space for people who want a part, inside the tool that
|
||||
prints it.**
|
||||
|
||||
Three audiences, one interface:
|
||||
|
||||
- **The fourteen-year-old on a school laptop.** Free software, on the machine
|
||||
they already have, with no account, no subscription, no licence and no
|
||||
tutorial. They open the tab because they want a bracket for a bike light, and
|
||||
an hour later it is printing. This is not the charity case at the bottom of
|
||||
the list — it is the reason the project is worth doing. A CAD tool that only
|
||||
the equipped can run is a tool for people who were already going to design
|
||||
something; this one has to be a creative instrument in the hands of someone
|
||||
who did not yet know they could make things. Everything in §6.1 exists to
|
||||
keep that door open, and nothing gets to close it for the convenience of the
|
||||
other two audiences.
|
||||
- **The maker** who has an idea and a printer, and who has bounced off FreeCAD.
|
||||
They should be modelling something real within ten minutes of first opening
|
||||
the tab, without a tutorial, without knowing the word "constraint".
|
||||
- **The mechanical designer** who needs assemblies, mates, exploded views,
|
||||
variables, and a feature history they can edit six months later. They should
|
||||
not have to leave for SolidWorks the moment the work gets serious.
|
||||
|
||||
The order matters. When a decision helps one audience and hurts another, the
|
||||
earlier one wins unless there is a written argument for why not.
|
||||
|
||||
The reference for *how it feels* is Shapr3D: direct, gestural, quiet, almost no
|
||||
chrome, depth revealed by what you touch rather than by what is on screen. The
|
||||
anti-references are Blender (a modal keyboard language you must learn before the
|
||||
first success) and FreeCAD (a workbench-and-dialog architecture where the
|
||||
geometry is a preview of a form you fill in elsewhere).
|
||||
|
||||
We are not cloning Shapr3D's feature set. We are adopting its *interaction
|
||||
economy*: the smallest number of visible controls that still makes an expert
|
||||
fast.
|
||||
|
||||
**And one thing neither reference has:** Orca-CAD lives inside a slicer. The
|
||||
plate, the nozzle, the material and the print constraints are known to the
|
||||
application at design time. Designing for print is not a plugin here, it is the
|
||||
home advantage. Where a rule below trades generality for print-awareness, it
|
||||
trades in favour of print-awareness.
|
||||
|
||||
## 3. The laws
|
||||
|
||||
Non-negotiable. A change that breaks one of these does not get merged on the
|
||||
grounds that it was easier, that the alternative is more work, or that another
|
||||
CAD does it that way. Each law carries a test — the question a reviewer asks.
|
||||
|
||||
### L1 — Geometry first: you point, then you act
|
||||
|
||||
Controls live **on the geometry**: handles, arrows, points, small circles and
|
||||
boxes, with an inline label tab for typed values. Not in a side panel of combos
|
||||
and spin fields.
|
||||
|
||||
The canonical gesture: **select a face or plane in the viewport, then click the
|
||||
sketch tool.** Never: click the sketch tool, then choose a plane from a list.
|
||||
The tool consumes what you pointed at — and, better still, the thing you pointed
|
||||
at offers the tool itself (§4).
|
||||
|
||||
> **Test.** Can the operation be performed start to finish without the pointer
|
||||
> leaving the viewport, except to press the tool itself? If a control had to be
|
||||
> added to a panel to make it work, the design is not finished.
|
||||
|
||||
This is the law the others serve. It was stated after two proposals in a row
|
||||
reached for a dropdown, and the failure mode it names is real and recurrent: a
|
||||
fix that "adds a row to the plane combo" is the side-panel pattern wearing a
|
||||
different hat.
|
||||
|
||||
### L2 — Everything draggable is typable, and everything typable is draggable
|
||||
|
||||
Any value produced by direct manipulation (a fillet radius, an extrude depth, a
|
||||
pattern spacing, a plane offset) shows a live label on the geometry, and that
|
||||
label is an editable field. Any value entered numerically has a corresponding
|
||||
handle in the viewport.
|
||||
|
||||
Dragging is for finding the answer. Typing is for committing to it. A tool that
|
||||
offers only one of the two is half a tool.
|
||||
|
||||
> **Test.** Point at the number the tool produces. Can you drag it? Can you
|
||||
> click it and type? Both must be yes.
|
||||
|
||||
### L3 — Noun then verb, always the same way round
|
||||
|
||||
Selection precedes action, without exception, across sketch tools, features,
|
||||
dress-up, booleans and mates. There is no tool in the product that is armed
|
||||
first and asks for its input afterwards.
|
||||
|
||||
> **Test.** Does this tool work if the user has already selected the thing they
|
||||
> want it applied to? Does it work *only* that way?
|
||||
|
||||
### L4 — No modal dialog in the modelling loop
|
||||
|
||||
Dialogs belong to document-level actions: open, save, import, export, preferences.
|
||||
Modelling never opens one. A feature that needs three values gets three labels on
|
||||
the geometry, not a form; a feature that needs confirming gets a ghost preview and
|
||||
a confirm/cancel puck in the scene beside it (§4.2) — an object, not a window: the
|
||||
camera still orbits, the values are still editable, nothing is blocked.
|
||||
|
||||
> **Test.** Between starting an operation and seeing its result, does a window
|
||||
> appear that must be dismissed? If yes, redesign.
|
||||
|
||||
### L5 — One click, one visible change
|
||||
|
||||
Every click either changes what is on screen or tells the user why it did not.
|
||||
A click that opens something invisible, arms an invisible state, or requires a
|
||||
second identical click to have any effect is a defect, not a design.
|
||||
|
||||
This law exists because we shipped its violation twice. Sketch-tool family
|
||||
buttons were flyouts whose first click only rendered a pressed state — three
|
||||
separate sessions filed bugs against tools that were working. Solid picking used
|
||||
a click *cycle* (first click selects the body, second refines to the face), so
|
||||
sketching on a face appeared broken to anyone who clicked a face once, the way
|
||||
every human does.
|
||||
|
||||
> **Test.** Perform the gesture exactly once, as a first-time user would. Take a
|
||||
> screenshot. Is the state visibly different, and is the difference the one the
|
||||
> user intended?
|
||||
|
||||
### L6 — The default is the answer four times out of five
|
||||
|
||||
Every option that has a default must have the *common* answer as its default,
|
||||
measured against real parts, not against generality. "New body" as the default
|
||||
result of an extrude is wrong: most extrudes join. Radius as the input for a
|
||||
circle is wrong: drawings give diameter.
|
||||
|
||||
> **Test.** Take ten real parts. In how many is the default correct? Below eight,
|
||||
> change the default or infer it from context.
|
||||
|
||||
### L7 — Errors are caught before the commit, in the user's words
|
||||
|
||||
A self-intersecting profile, a cut that removes no material, a wall thinner than
|
||||
the nozzle: these are reported at the moment they become knowable, on the
|
||||
geometry that is wrong, phrased as what happened and what to do — not as a kernel
|
||||
exception after the fact, and never silently.
|
||||
|
||||
> **Test.** Is the failure detectable before the user commits? Then it must be
|
||||
> reported before the user commits. Read the message aloud: does it name a thing
|
||||
> the user can see and an action they can take?
|
||||
|
||||
### L8 — The camera is the application's job
|
||||
|
||||
Selecting a sketch plane orients the view to it. Committing a feature does not
|
||||
throw the camera away. Zoom-to-fit exists and is one keystroke. The user is never
|
||||
required to fight the view in order to reach the geometry, and orbit is bound to
|
||||
the gesture people actually try.
|
||||
|
||||
> **Test.** Count camera manipulations in a representative modelling session.
|
||||
> Any camera action the application could have performed for the user is a bug.
|
||||
|
||||
### L9 — Accessible by construction, not by retrofit
|
||||
|
||||
The floor, applied to every new interaction (details in §6.2): full keyboard
|
||||
reach, no meaning carried by colour alone, hit targets that survive a shaky hand
|
||||
and a HiDPI screen, legible labels over an arbitrary 3D background, no gesture
|
||||
that depends on timing.
|
||||
|
||||
> **Test.** Drive the whole interaction from the keyboard. Then drive it in
|
||||
> greyscale. Both must work.
|
||||
|
||||
### L10 — Vocabulary from the drawing office
|
||||
|
||||
Names come from the language of people who make parts: fillet, chamfer, boss,
|
||||
rib, counterbore, mate, exploded view. Not from the kernel (no "boolean
|
||||
subtract", no "B-rep"), not from invented product-speak. Where the drawing-office
|
||||
word and the beginner's word differ, use the drawing-office word and make the
|
||||
tooltip teach it — an approachable tool that leaves the user unable to talk to a
|
||||
machinist has failed them.
|
||||
|
||||
> **Test.** Would a shop-floor engineer recognise this word? Would a first-time
|
||||
> user be able to look it up and find a real definition?
|
||||
|
||||
### L11 — The floor is a school laptop, and nothing is behind a door
|
||||
|
||||
The product runs, completely, on a low-end laptop with integrated graphics and a
|
||||
small screen, offline, with no account, no subscription and no feature withheld.
|
||||
No capability in this document is reserved for a paid tier, a cloud service, a
|
||||
plugin, or a machine with a discrete GPU — there is one product and everybody
|
||||
gets all of it.
|
||||
|
||||
> **Test.** On the reference low-end machine (§6.1), at 1366×768, with the
|
||||
> network cable pulled and no account ever created: does this feature work, and
|
||||
> is it usable at an honest frame rate? Any "no" is a defect, not a limitation.
|
||||
|
||||
## 4. Interaction grammar — object-driven
|
||||
|
||||
The rules above compose into one sentence the whole product obeys:
|
||||
|
||||
> **Point at geometry → the geometry offers what can be done to it → choose the
|
||||
> tool → manipulate handles and type exact values → confirm or cancel.**
|
||||
|
||||
The selection does not merely feed the tool. **The selection determines which
|
||||
tools exist.** Pick a planar face and the product shows you the small set of
|
||||
things a planar face can become — sketch on it, extrude it, hole it, shell it,
|
||||
put a datum on it. Pick an edge and that set is fillet, chamfer, and the sketch
|
||||
tools that can use it as a reference. Nothing else is offered, because nothing
|
||||
else is possible.
|
||||
|
||||
This is the single largest thing we can do for a first-time user, and it is
|
||||
worth stating as the reason: a beginner's difficulty is not operating a tool,
|
||||
it is **not knowing which tools apply to what they are looking at**. A palette
|
||||
of sixty icons answers a question they cannot yet ask. A face that offers its
|
||||
own five verbs teaches the model of the product by using it. It also removes an
|
||||
entire class of failure — a tool that silently does nothing because the
|
||||
selection was wrong can no longer be reached.
|
||||
|
||||
### 4.1 The offer, and the one thing that makes it work
|
||||
|
||||
The flow, in full:
|
||||
|
||||
> **left-click the geometry to select it → right-click to open the offer → a
|
||||
> vertical list, always in the same order, each row an icon, a name and its
|
||||
> keyboard shortcut → click.**
|
||||
|
||||
- **Selecting and acting are separate gestures.** Left-click only ever selects,
|
||||
so pointing at things is quiet — nothing pops up while you look around.
|
||||
Right-click on the selection opens the offer, at the pointer, over the
|
||||
geometry it acts on.
|
||||
- **Order is fixed and it is the whole point.** A verb occupies one permanent
|
||||
row, and that row is the same in every selection where the verb appears.
|
||||
Dress-up is the fourth row on an edge, on a face, on a body, on the day the
|
||||
product ships and two years later. The hand learns the position; the eye stops
|
||||
being needed.
|
||||
- **What does not apply is DISABLED IN PLACE, never removed.** This is the
|
||||
single strongest thing the list does, and it is why it beat the radial we
|
||||
drew first: a greyed row still carries its name *and the reason it is grey* —
|
||||
"Create a sketch, or pick a solid face, first", "Create a solid body to
|
||||
pattern first" — in the words the product already ships. On a first-run
|
||||
document the offer is therefore not a mostly-empty control but a map of what
|
||||
the product does and what you have to do first.
|
||||
- **It is an accelerator, not a toll gate.** The toolbar and the single-letter
|
||||
shortcuts keep working exactly as they do now, and pressing a tool directly
|
||||
consumes the same selection (L3). An expert never has to open the offer; a
|
||||
beginner never has to know the toolbar exists. Both routes land in the same
|
||||
place — this is the only way one interface serves §2's three audiences.
|
||||
- **Every row shows its keyboard shortcut**, right-aligned so the keys stack
|
||||
into a column the eye learns without trying, beside the icon and the
|
||||
drawing-office word (L10). This is deliberate: the offer is the path by which
|
||||
a user stops needing the offer. You reach for fillet in its row, the row says
|
||||
"F", and one day your hand types F before the menu has finished opening. A
|
||||
menu that teaches its own shortcut is how a beginner becomes the power user
|
||||
who never opens it — the same interface at two speeds, with no "advanced mode"
|
||||
between them (§7).
|
||||
- **A family with more than one applicable verb opens a submenu** to the side,
|
||||
in its own fixed order. A family with exactly one shows that verb directly, so
|
||||
the common path is never one click longer than it needs to be.
|
||||
- **It never blocks the view of what it acts on**: it opens beside the pick,
|
||||
never over it, with a thin leader back to the point it belongs to, and it
|
||||
dismisses the moment the selection changes.
|
||||
- **The header names what is selected** ("Top face · Body 1"), because a user
|
||||
who mis-picked should find that out before choosing a verb, not after.
|
||||
|
||||
#### Opening the offer on every machine
|
||||
|
||||
Right-click is the primary gesture and every platform must have a first-class
|
||||
equivalent — this is a reach requirement (L11), not a nicety:
|
||||
|
||||
| Input | Gesture |
|
||||
|---|---|
|
||||
| Two-button mouse | right-click |
|
||||
| Trackpad | two-finger tap (the OS-standard secondary click) |
|
||||
| macOS, one-button mouse | **long-press**, and Ctrl-click, which is the platform convention |
|
||||
| Keyboard | the Menu key, or Shift+F10, on the current selection |
|
||||
| Touch / pen | long-press |
|
||||
|
||||
The long-press is an **additional** route, never the only one — §6.2 forbids
|
||||
press-and-hold as a sole path to a function, and it stays forbidden. Every
|
||||
opening gesture is reachable at least two ways on every platform, and the
|
||||
keyboard route exists everywhere. A long-press must show that it is charging
|
||||
(a growing ring under the finger) so a user who holds too briefly learns why
|
||||
nothing happened rather than concluding the product is broken (L5).
|
||||
|
||||
#### The row-constancy invariant
|
||||
|
||||
This is the rule that has to survive every future feature, so it is written as
|
||||
an invariant rather than as advice:
|
||||
|
||||
> **Every verb has exactly one row index in the offer. That index is identical
|
||||
> for every selection type in which the verb appears. Verbs that do not apply to
|
||||
> the current selection are DISABLED IN PLACE, with their reason — the offer is
|
||||
> never compacted, re-sorted or re-ordered. Adding a verb never changes the
|
||||
> index of an existing one.**
|
||||
|
||||
Two consequences the group must accept together with the invariant:
|
||||
|
||||
- **No adaptive ordering. Ever.** Not most-used-first, not recently-used-first,
|
||||
not per-selection frequency. An offer that rearranges itself to be helpful
|
||||
destroys the only thing that made it fast, and it does so precisely for the
|
||||
user who has just started to learn it. (Office 2000's adaptive menus are the
|
||||
textbook case; they were removed.)
|
||||
- **Greyed rows are the price, and they are cheap.** A compacted menu is shorter
|
||||
and unlearnable. A constant one is a few rows longer, teaches while it waits,
|
||||
and is memorised in a week.
|
||||
|
||||
#### The map — RATIFIED 2026-07-31
|
||||
|
||||
The invariant is not negotiable, and as of 2026-07-31 neither is the assignment:
|
||||
the row order below is **ratified**. It was argued once; it is not argued again.
|
||||
Changing an index from here on is a breaking change to every user's muscle
|
||||
memory and needs the group, not a pull request (§9 q12).
|
||||
|
||||
Eight families, ordered so the sequence itself has a logic: material is created,
|
||||
grows, is taken away, is refined, is repeated, is moved, is referred to, is
|
||||
edited.
|
||||
|
||||
| Row | Family | On a face | On an edge | On a body | On text/art |
|
||||
|---|---|---|---|---|---|
|
||||
| **1** | Create | Sketch on it | — | — | Edit text |
|
||||
| **2** | Add material | Extrude, thicken | — | Combine, thicken | Extrude |
|
||||
| **3** | Remove | Hole, shell | Thread | Shell, cut, split | — |
|
||||
| **4** | Dress-up | Draft | Fillet, chamfer | Fillet, chamfer | — |
|
||||
| **5** | Repeat | Pattern | Pattern along it | Pattern, mirror | Pattern |
|
||||
| **6** | Transform | Align to, mate | — | Move, mate | Move, size |
|
||||
| **7** | Reference | Plane, axis, measure | Axis, measure | Project, measure, mass | — |
|
||||
| **8** | Modify | Delete face, edit | — | Edit, colour, delete | Replace art |
|
||||
|
||||
A dash means the row is drawn greyed for that selection, with its reason.
|
||||
|
||||
The authoritative version of this table is **`docs/ux/tool_atlas.json`**, which
|
||||
carries all 52 verbs with their preconditions and their refusal strings, taken
|
||||
from the code rather than from memory. Every state it produces — 20 selection
|
||||
kinds × 2 document states, 40 primary menus and 73 submenus — is rendered by
|
||||
`docs/ux/mockups/gen_offer_mockups.py` into `docs/ux/offer_atlas.html`. Read the
|
||||
atlas before proposing a change to the map; the generator refuses to render an
|
||||
address collision, so the map cannot silently rot.
|
||||
|
||||
#### Rejected: the radial ring
|
||||
|
||||
The first design put the eight families at eight compass points around the pick.
|
||||
It is recorded here because it is a good idea that loses on evidence, and
|
||||
someone will propose it again:
|
||||
|
||||
- an inapplicable slot could only be drawn empty, and **an empty slot says
|
||||
nothing** — the reason text above has nowhere to live;
|
||||
- the measured fill was **3.45 of 8 slots**, so most of the control was blank
|
||||
most of the time, and on a fresh document only two of eight were live;
|
||||
- sketch-mode *Create* needs **nine** addresses; eight forced two primitives
|
||||
behind a "More" slot, and a ninth position costs the 45° spacing that made the
|
||||
ring worth having;
|
||||
- long translated names do not fit around a circle, and screen readers and arrow
|
||||
keys need bespoke handling a list gets for free;
|
||||
- a 380 px disc over the model costs more on a 1366×768 screen than a 324 px
|
||||
list beside it (§6.1).
|
||||
|
||||
What it kept — equidistant targets and a future flick gesture — buys little in a
|
||||
product whose experts live on the keyboard by design.
|
||||
|
||||
### 4.2 Confirm and cancel are objects, not gestures
|
||||
|
||||
The old rule — click empty space to commit — is withdrawn. It was an invisible
|
||||
gesture with a destructive meaning: nothing on screen said it, and a stray click
|
||||
committed a feature the user was still adjusting. That is exactly what L5
|
||||
forbids, and it is hostile to the audience §6.1 exists for.
|
||||
|
||||
- **A pending feature carries a confirm/cancel puck**, attached to the geometry
|
||||
it is editing, next to its handles: ✓ commits, ✗ discards. Enter and Escape
|
||||
mirror them for the keyboard (L9). It is drawn where the user's attention
|
||||
already is, and it is the only thing in the viewport that commits.
|
||||
- **Empty space now means "clear the selection"** — the safe meaning, and the
|
||||
same meaning everywhere.
|
||||
- **This is not a dialog** (L4). It is two objects in the scene, on the
|
||||
geometry, non-modal: the camera still orbits, the tree is still there, the
|
||||
values are still editable while it waits.
|
||||
- **Continuous tools do not ask.** Drawing a line, a rectangle, a circle commits
|
||||
each entity as its own gesture completes — a ✓ per line would destroy the
|
||||
inner loop. The puck belongs to *features* (extrude, fillet, hole, pattern,
|
||||
mate) and to sketch edits that hold a pending state. Enter/Escape end a
|
||||
continuous tool rather than confirming an entity.
|
||||
- **Ambiguity resolves toward keeping work, never toward losing it.** Starting
|
||||
another operation while a valid feature is pending commits it rather than
|
||||
discarding it; if it is not valid, the product says why (L7) and keeps it
|
||||
pending. Since undo reaches everything (§6.1), the recoverable direction is
|
||||
always the right default.
|
||||
|
||||
### 4.3 The rest of the grammar
|
||||
|
||||
- **The status line is one imperative sentence** naming what the tool wants
|
||||
next, and it names the target when the target came from a selection
|
||||
("Circle — click centre, then radius · on the picked face"). It is the
|
||||
authoritative feedback surface for the armed tool; the toolbar is not.
|
||||
- **Hover previews, click commits.** A hover shows the ghost of what a click
|
||||
would do wherever this is cheap to compute.
|
||||
- **Selection is persistent and visible** until consumed or cleared. A tool that
|
||||
consumes a selection clears it, so the next feature cannot silently inherit it.
|
||||
- **Every gesture is undoable**, and the feature tree is editable history, not a
|
||||
log. Re-editing a feature re-enters the same on-geometry interaction that
|
||||
created it — including its offer and its puck.
|
||||
|
||||
## 5. Layout and screen budget
|
||||
|
||||
The viewport is the application. Chrome is a tax on it.
|
||||
|
||||
- **One toolbar**, contextual to the mode (model / sketch). Tools are grouped by
|
||||
what they make, not by which subsystem implements them.
|
||||
- **A left rail for the document, not for parameters**: feature tree, bodies,
|
||||
variables. It answers "what exists", never "what value should this be".
|
||||
- **No parameter panel.** Where one exists today it is technical debt with a
|
||||
scheduled removal (§10).
|
||||
- **Print context is ambient**, not a panel: the plate is visible in the design
|
||||
space, and print-domain warnings appear on the geometry that will fail.
|
||||
- **Nothing is added to permanent chrome without removing something**, or
|
||||
demonstrating that the addition is used in the majority of sessions.
|
||||
- **The budget is set by the smallest screen we serve**, 1366×768 (§6.1) — not
|
||||
by the reviewer's monitor. Chrome that fits a 27-inch display and swallows a
|
||||
laptop's has not fitted, it has just failed somewhere the author cannot see.
|
||||
|
||||
## 6. Accessibility — reach first, then the assistive floor
|
||||
|
||||
"Accessible" means two different things and the product owes both. §6.1 is about
|
||||
**who can get in at all**; §6.2 is about **who can operate it once inside**.
|
||||
Neither is a phase. Both are merge requirements.
|
||||
|
||||
### 6.1 Reach — the door has to be open
|
||||
|
||||
The premise of the whole project: someone with no money, no licence, no account,
|
||||
no fast machine and no teacher can open this and make a real thing. Free
|
||||
software on a school laptop is the only path to a CAD tool that reaches people
|
||||
who were never going to be handed one. If a design decision quietly raises the
|
||||
cost of entry, it has broken the premise, however elegant it is.
|
||||
|
||||
- **The reference machine.** A 5-year-old laptop: dual/quad-core CPU,
|
||||
**integrated graphics**, 8 GB RAM, **1366×768** screen, no discrete GPU. The
|
||||
Design tab must be usable there, and any interaction that needs more is a
|
||||
design failure to be solved, not a requirement to be documented. The GPU path
|
||||
degrades gracefully to software rendering rather than refusing to start; the
|
||||
viewport stays interactive while the kernel thinks.
|
||||
- **1366×768 is the layout target, not the stretch case.** A form-heavy side
|
||||
panel is not merely inelegant on that screen — it takes the model off it.
|
||||
This is the second, independent argument for the whole of L1 and §5.
|
||||
- **No account, no cloud, no connection.** The product works forever with the
|
||||
network unplugged. Nothing is uploaded, no sign-in gates any feature, no
|
||||
telemetry is required to use it. A school network that blocks everything must
|
||||
not be able to block this.
|
||||
- **No tier, no plugin wall, no "pro".** Every feature named in this document is
|
||||
in the product everyone downloads. Assemblies and exploded views are not the
|
||||
paid half.
|
||||
- **Files belong to the user**, on their disk, in a format that outlives the
|
||||
project: the design travels inside the ordinary project file, and the geometry
|
||||
exports to STEP and mesh formats anyone can open.
|
||||
- **Learnable without instruction.** The first solid comes with no
|
||||
documentation, no video and no tutorial mode — from noticing that a face can
|
||||
be clicked. Tooltips teach the vocabulary (L10) at the moment it is needed;
|
||||
nothing is explained in a manual the user will never open.
|
||||
- **Plain language at the entry tier.** The Make tier speaks in words a
|
||||
thirteen-year-old reads without stopping. Precision comes with the tier that
|
||||
needs it, and everything is translated, because "accessible" in English only
|
||||
is not accessible.
|
||||
- **Exploration must be free.** Undo reaches everything, work is never lost to a
|
||||
wrong click, and no dialog ever asks the user to be sure. A tool that punishes
|
||||
experiments teaches people to stop experimenting, which is the one thing this
|
||||
audience cannot afford to learn.
|
||||
- **The product never blames the user.** Failures are stated as what happened
|
||||
and what to do (L7). "Invalid input" is not an acceptable sentence anywhere.
|
||||
|
||||
### 6.2 Assistive floor
|
||||
|
||||
- **Keyboard**: every operation reachable and completable without a pointer.
|
||||
Single-letter shortcuts for sketch tools, shown in the offer itself (§4.1) as
|
||||
well as in the tooltip. The offer opens from the keyboard (Menu key or
|
||||
Shift+F10) and walks by arrow key and by type-ahead, so the row map works for
|
||||
someone who never touches the pointer. A visible focus state on every
|
||||
focusable element. No shortcut that only works while the pointer happens to be
|
||||
over the canvas.
|
||||
- **Colour**: never the sole carrier of meaning. Selection is colour *and*
|
||||
outline; an error is colour *and* an icon *and* text. Verify in greyscale.
|
||||
- **Contrast**: labels over the 3D viewport get a scrim or halo so 4.5:1 holds
|
||||
against any background the model can produce, including a white body under a
|
||||
white plate.
|
||||
- **Targets**: handles and grips no smaller than 32 px at 100 % scale, scaling
|
||||
with the OS factor; the grab tolerance is larger than the drawn glyph.
|
||||
- **Timing**: no double-click-to-mean-something-else, no press-and-hold as the
|
||||
only route to a function, no cycle that depends on repeated clicks
|
||||
(see L5). The long-press that opens the offer on a one-button Mac and on touch
|
||||
(§4.1) is explicitly an *additional* route — Ctrl-click, two-finger tap and
|
||||
the keyboard all reach the same place — and it shows its own progress while
|
||||
charging, so it never fails silently.
|
||||
- **Motion**: animation is functional (showing where a thing went), never
|
||||
decorative, and it respects the reduced-motion preference.
|
||||
- **Text**: no fixed-width assumptions; the UI holds together in German and in
|
||||
Chinese, at 125 % and 200 % scale. Every string routed through the normal
|
||||
translation path.
|
||||
|
||||
## 7. Depth without clutter — the three tiers
|
||||
|
||||
Power for experts is delivered by **progressive disclosure of tools, never by
|
||||
relocation of tools**. A tool that appears in a later tier is in the same place
|
||||
it will always be; it is simply not shown yet.
|
||||
|
||||
| Tier | Who | What appears |
|
||||
|---|---|---|
|
||||
| **Make** | first hour | Sketch, extrude, revolve, hole, fillet/chamfer, move, commit to plate |
|
||||
| **Model** | competent user | Patterns, shell, draft, sweep/loft, booleans, reference geometry, variables, import/export |
|
||||
| **Mechanism** | mechanical designer | Assemblies and mates, exploded views, interference detection, surfaces, feature-level editing of imported solids |
|
||||
|
||||
Rules that keep this honest:
|
||||
|
||||
1. **Tiers are non-modal.** No mode switch, no workbench selector, no "advanced
|
||||
mode" toggle that changes the meaning of anything. The tier only governs what
|
||||
is *offered*.
|
||||
2. **A tier reveals itself by use.** Using a body reveals boolean tools; adding
|
||||
a second body reveals assembly tools. The product notices what you are doing.
|
||||
3. **Nothing moves when a tier appears.** A user who learned where fillet lives
|
||||
finds it in the same place forever.
|
||||
4. **An expert tool obeys the same grammar** as a beginner tool. Mates are
|
||||
picked in 3D like everything else, not configured in a table.
|
||||
5. **Exploded views are a view state**, not a document mode — reversible,
|
||||
draggable along mate axes, and never a separate file.
|
||||
|
||||
## 8. Designing for print — the home advantage
|
||||
|
||||
Design-time knowledge the application already has, and must use:
|
||||
|
||||
- **The plate is present** in the design space, at the real size, with the real
|
||||
origin. Committing a body to the plate is one action and preserves placement.
|
||||
- **Print-domain checks run on the model, on the geometry, before slicing**:
|
||||
walls thinner than the nozzle, unsupported overhangs beyond the material's
|
||||
angle, features smaller than the layer height, a part that does not fit the
|
||||
build volume.
|
||||
- **These are warnings on the geometry, never a report.** The thin wall glows;
|
||||
the tooltip says how thin and what the nozzle is.
|
||||
- **Material and machine context is inherited** from the active slicer profile,
|
||||
not re-entered in the Design tab.
|
||||
- **The round trip is preserved**: editing a design after slicing returns to the
|
||||
feature history, not to a mesh.
|
||||
|
||||
## 9. The review gate
|
||||
|
||||
Every pull request that touches the Design tab UI answers these, in the PR body.
|
||||
A "no" that is not accompanied by an argument is a request for changes.
|
||||
|
||||
1. Which law (L1–L11) does the change most directly serve?
|
||||
2. Can the whole operation be completed without the pointer leaving the
|
||||
viewport? If not, why is this the exception?
|
||||
And: does the relevant selection *offer* this tool (§4.1), or must the user
|
||||
already know it exists?
|
||||
3. Are the values draggable *and* typable?
|
||||
4. Screenshot of the state after **exactly one** click of the new gesture,
|
||||
performed as a first-time user.
|
||||
5. Keyboard-only walkthrough: does it complete?
|
||||
6. Greyscale screenshot: is every state still distinguishable?
|
||||
7. What was **removed**? (Net additions to permanent chrome require an argument.)
|
||||
8. Which tier does it belong to, and does it appear without moving anything else?
|
||||
9. What does it do when the geometry is invalid, and is that reported before the
|
||||
commit?
|
||||
10. Interaction cost: actions required for the canonical task it addresses,
|
||||
before and after.
|
||||
11. Reach (L11): screenshot at 1366×768 with the panel open — is the model still
|
||||
on screen? Does it run on integrated graphics? Does it need the network, an
|
||||
account, or a file the user cannot keep?
|
||||
12. If the change adds or moves a verb in the offer: which row, and is it that
|
||||
verb's row in **every** selection where it appears? Did any existing verb's
|
||||
index change? (If yes, this is not a UI change, it is a breaking change to
|
||||
every user's muscle memory, and it needs the group — see §4.1.) Was
|
||||
`docs/ux/tool_atlas.json` updated and the atlas regenerated?
|
||||
13. If the change adds a pointer gesture: what is its keyboard equivalent, and
|
||||
what does a one-button Mac, a trackpad and a touch screen do (§4.1)?
|
||||
|
||||
## 10. Where we stand today — honest inventory
|
||||
|
||||
Complying with the laws already:
|
||||
|
||||
- Sketch inline editors — draw an entity and its dimension tab opens on the
|
||||
geometry; Tab walks Length → Width → Angle.
|
||||
- Fillet/chamfer draggable radius arrow with an editable value label.
|
||||
- Extrude depth arrow; move-body three-axis arrows.
|
||||
- Datum-plane resize handles and offset arrow; ghost reference planes picked in
|
||||
3D.
|
||||
- Imported-art place/size gizmo.
|
||||
- Sketch plane taken from the picked face, with the target named in the status
|
||||
line, and the sketch-plane dropdown deleted outright.
|
||||
|
||||
Violating them, with removal scheduled:
|
||||
|
||||
- **Every tool card is a two-column form** of combos and spin fields in the left
|
||||
panel. This is the single largest debt in the product and the reason this
|
||||
document exists. Tracked as an epic; each card is replaced by its on-geometry
|
||||
equivalent, not improved in place. It fails L1 and it fails L11 twice over —
|
||||
on a 1366×768 screen the cards leave the model a strip.
|
||||
- Seven remaining plane pickers still populate a combo instead of consuming a
|
||||
viewport selection.
|
||||
- Pattern has no on-geometry spacing arrow or count badge.
|
||||
- Hole is positioned by X/Y fields rather than by a point on a face.
|
||||
- Booleans and cuts pick their operands from lists rather than in 3D.
|
||||
- Fillet/chamfer edge selection still requires the click cycle L5 forbids.
|
||||
- **Selecting geometry offers nothing.** There is no contextual offer (§4.1):
|
||||
the user faces the full toolbar whatever they have picked, and finds out that
|
||||
a tool did not apply by it doing nothing. This is the largest single item of
|
||||
new work the charter asks for. The map and every state of it are already
|
||||
drawn (`docs/ux/offer_atlas.html`); what the group owes itself before the code
|
||||
is ratifying the row order, since every verb built before that lands has to be
|
||||
addressed afterwards anyway.
|
||||
- **Committing is an invisible click in empty space** rather than the
|
||||
confirm/cancel puck of §4.2 — the exact gesture that rule withdraws.
|
||||
|
||||
Nothing on the violating list is defended. The only open question for each is
|
||||
what its on-geometry replacement should be.
|
||||
|
||||
## 11. How the group works
|
||||
|
||||
**Roles.** Product/UX lead (owns this document and casts the tie-break vote on
|
||||
interaction questions); kernel maintainer; GUI maintainer; a print-domain
|
||||
reviewer; a mechanical-design reviewer who uses the product on real work; an
|
||||
accessibility reviewer covering both senses of §6 — reach and assistive — who
|
||||
owns the reference machine and actually runs on it. One person may hold more
|
||||
than one role; the UX lead and the mechanical-design reviewer should not be the
|
||||
same person, and nobody reviews reach from a workstation.
|
||||
|
||||
**The absent audience needs a seat.** The fourteen-year-old is not in the room
|
||||
and cannot file an issue. Someone in the group is accountable for B5 and B6, and
|
||||
the group watches real first-timers use the product on the reference machine at
|
||||
least once a quarter — school, makerspace, or a friend's kid. Everything else in
|
||||
this document can be argued from principle; approachability can only be
|
||||
observed.
|
||||
|
||||
**Cadence.** A short weekly review of open interaction proposals. A monthly pass
|
||||
over the violating inventory in §10 — anything that has not moved in two months
|
||||
is either scheduled or explicitly accepted as permanent, with a reason written
|
||||
into this document.
|
||||
|
||||
**How a change moves.**
|
||||
|
||||
1. *Problem* — a described user difficulty, ideally with an interaction-cost
|
||||
measurement, never a solution in disguise.
|
||||
2. *Sketch* — one or two on-geometry interaction proposals, drawn or described
|
||||
as a gesture sequence. Reviewed against §3 before any code.
|
||||
3. *Prototype* — built behind whatever the smallest safe path is, driven end to
|
||||
end on a real display, and screenshotted at each state.
|
||||
4. *Gate* — §9 answered in the PR.
|
||||
5. *Merge*, then update §10.
|
||||
|
||||
**Decisions are written down.** Any resolution that constrains future work is
|
||||
appended to this document as a numbered law or as an accepted exception with its
|
||||
reasoning. A decision that lives only in a call is not a decision.
|
||||
|
||||
**How disagreements resolve.** Against the laws first. If the laws do not decide
|
||||
it, the tie-break is the interaction cost measured on the canonical tasks in
|
||||
§12; if that does not decide it, the UX lead chooses and records why.
|
||||
|
||||
## 12. Canonical tasks — the benchmark
|
||||
|
||||
The measure of every UX change is the cost of these five tasks. Each is timed and
|
||||
counted (clicks, keystrokes, camera actions, mode switches) on the headless rig
|
||||
and, periodically, with real users who have not seen the product.
|
||||
|
||||
| # | Task | What it exercises |
|
||||
|---|---|---|
|
||||
| **B1** | Bracket: sketch an L, extrude, two holes, fillet the inside corner, send to plate | The inner loop |
|
||||
| **B2** | Change a hole diameter and the plate thickness, six features deep, and rebuild | Parametric editability |
|
||||
| **B3** | Take an imported STEP, delete a boss, close the face, thicken a wall to nozzle width | Direct editing + print awareness |
|
||||
| **B4** | Two parts, one revolute mate, check interference, produce an exploded view | The Mechanism tier |
|
||||
| **B5** | First-run: from opening the Design tab to a print-ready solid, no documentation | Approachability |
|
||||
| **B6** | B1 again, on the reference machine at 1366×768, offline, on a fresh account-less install | Reach (L11) |
|
||||
|
||||
Every task is run on the reference machine of §6.1, not on a workstation — a
|
||||
number measured on a fast desktop describes an experience most of our users will
|
||||
never have. B6 repeats the inner loop under the full entry conditions so that
|
||||
reach is a measured quantity and not an intention.
|
||||
|
||||
Targets are set once each task has been measured on the current build. B5's
|
||||
target is expressed in minutes-to-first-solid **by someone who has never seen a
|
||||
CAD program**, and it is the number this project is ultimately judged by.

### Appendix — anti-patterns we have already paid for
|
||||
|
||||
Kept because each cost real time and each is easy to reintroduce.
|
||||
|
||||
- **The dropdown that grew a row.** Fixing "cannot sketch on a face" by adding a
|
||||
"Face of Body 1" entry to a plane combo. It reads as a small fix and it is the
|
||||
side-panel architecture reproducing itself.
|
||||
- **The invisible first click.** Flyout buttons and pick cycles whose first click
|
||||
changes nothing meaningful. Filed as bugs three separate times against working
|
||||
code, and made a real bug look fixed when it was not.
|
||||
- **The fix verified through a path the user will never take.** A face-sketch fix
|
||||
confirmed by double-clicking to reach face level. Users click once. A fix
|
||||
reachable only by an undiscoverable gesture is indistinguishable from no fix.
|
||||
- **The wrong feedback surface.** Measuring an armed tool by the toolbar, which
|
||||
never renders keyboard-armed state. The status line is the surface that
|
||||
answers.
|
||||
- **The silent success.** A cut that removed no material, reported as done. Now
|
||||
an error naming the likely cause.

---
|
||||
|
||||
## What is right, and precisely so
|
||||
|
||||
**The sloping ridge is implemented exactly as briefed.** From (0.00, 18.40, 17.27) to
|
||||
(0.00, 46.72, 10.66): 28.3 mm long, 6.61 mm drop, **13.1° slope**, and both ends sit dead on
|
||||
x = 0.00. It breaks 180° rotation on its own.
|
||||
|
||||
**20.0° uniform draft on all four snout flanks**, identical to within 0.1°:
|
||||
`(0,−0.94,0.342) (0.936,0.08,0.342) (0,0.94,0.342) (−0.936,0.08,0.342)`. That is a real,
|
||||
deliberate lead-in — it self-centres into a matching pocket, and it demoulds and prints.
|
||||
|
||||
**The eyes are exactly symmetric**: Ø9.87 at x = ±16.43, y = 48.01, matching to 0.01 mm.
|
||||
Someone mirrored those on purpose.
|
||||
|
||||
**The mating feature is extremely economical**: only **five edges** exist above the 3 mm plate —
|
||||
the ridge plus two flank edges at each end. Base plate is exactly 3.00 mm.
|
||||
|
||||
The low-poly constraint is honoured. All six cylinders are outline rounds and eye holes; none of
|
||||
them is a mating surface.
|
||||
|
||||
---
|
||||
|
||||
## The asymmetry is deliberate, and it is complete
|
||||
|
||||
**Correction.** A first pass read the left/right differences as an unfinished mirror. That was wrong:
|
||||
the asymmetry is intentional. Tested properly — every candidate self-symmetry, in the part's own
|
||||
centred frame, with a generous 0.1 mm tolerance:
|
||||
|
||||
| operation | edges mapped onto the part |
|
||||
|---|---|
|
||||
| identity | 81 / 81 — 100 % |
|
||||
| mirror about x = 0 (left/right) | **0 / 81** |
|
||||
| mirror about y = 0 (top/bottom) | **0 / 81** |
|
||||
| rotate 180° about Z | **0 / 81** |
|
||||
| rotate 90° about Z | **0 / 81** |
|
||||
| mirror about the diagonal | **0 / 81** |
|
||||
|
||||
**The symmetry group is trivial.** No rigid motion or reflection maps this part onto itself, so
|
||||
**every partial view determines the orientation uniquely** — you never need to see the whole face to
|
||||
know which way round it goes. That is the strongest possible result for a keying interface and it is
|
||||
exactly what the earlier abstract glyph work kept failing to achieve: a symmetric shape seen at a
|
||||
grazing angle, or half-occluded, gives an ambiguous read.
|
||||
|
||||
### Does it let you GRASP the orientation? Measured, not asserted.
|
||||
|
||||
Unique-in-principle and graspable-at-a-glance are different claims. The symmetry table proves the
|
||||
first. For the second, the front-on picture (outline + eyes + mouth, filled) was rasterised and
|
||||
compared against its own mirror and its own 180° rotation — the two ways a person can get it wrong.
|
||||
|
||||
**By size** (percentage of pixels that differ):
|
||||
|
||||
| width | vs mirror | vs rotated 180° |
|
||||
|---|---|---|
|
||||
| 16 px | 20.7 % | 26.0 % |
|
||||
| 24 px | 21.9 % | 30.9 % |
|
||||
| 32 px | 23.0 % | 28.1 % |
|
||||
| 48 px | 22.4 % | 30.6 % |
|
||||
| 80 px | 24.7 % | 31.0 % |
|
||||
| 160 px | 23.6 % | 31.0 % |
|
||||
|
||||
**The curve is flat.** The full signal is already there at 16 pixels and more resolution adds
|
||||
nothing. That is the whole result: **the orientation cue lives at low spatial frequency**, carried by
|
||||
the overall shape rather than by any detail. It therefore survives distance, blur, poor light,
|
||||
peripheral vision, a small print and a low-resolution screen. It is the exact opposite of the abstract
|
||||
disc glyph, whose roll cue was a small high-frequency feature and died at a grazing angle.
|
||||
|
||||
**Partial views — a claim I made and then withdrew.** I ran a masked-window test and concluded that
|
||||
a single quarter of the face was enough to read the orientation. **That test was invalid and the
|
||||
conclusion is wrong.** It compared a window of the original against *the same window* of the mirrored
|
||||
and rotated versions — which silently hands the observer the registration. It assumes you already
|
||||
know that the patch you are looking at is the top-left quarter, which is exactly the thing you would
|
||||
not know if you could only see a quarter.
|
||||
|
||||
**You need to see the whole face.** The cues here are *relational*: the big ear only means something
|
||||
next to the small ear, and the mouth offset only means something relative to the centreline. None of
|
||||
them is self-locating. Whole-face is the operating condition, and the design should be judged and
|
||||
used on that basis.
|
||||
|
||||
That does not weaken the size result above, which always used the complete silhouette: the whole face
|
||||
reads at 16 px. Needing all of it, and needing very little resolution of it, are compatible — and for
|
||||
a part held in a hand, seeing all of it is the normal case.
|
||||
|
||||
**The signal is allocated to the right risks.** The strongest cue (up to 41.7 %) guards against
|
||||
inserting it upside down — the mistake people actually make. The weakest (~23 %) guards the mirror
|
||||
case, which needs the part flipped over and which the protrusion already prevents mechanically.
|
||||
|
||||
It also does mechanical work beyond the ridge. The ridge alone breaks 180° rotation; the asymmetric
|
||||
outline additionally defeats the **mirrored-part** case — a mirror-image copy will not fit, so a
|
||||
modelling or printing mirror is caught at assembly rather than three steps later.
|
||||
|
||||
And for children specifically, a symmetric cartoon face reads as a mask; illustrators asymmetrise
|
||||
deliberately so a face reads as a *character*. The asymmetry is earning its keep three ways at once.
|
||||
|
||||
### What is worth keeping in mind anyway
|
||||
|
||||
**The ears differ by 42 %** — left 8.33 mm wide (top y 65.68), right 11.81 mm (top y 66.69). Both
|
||||
start at the same y = 60.79, so they read as a deliberate pair rather than an error. 42 % is well
|
||||
above the perceptual threshold: you see it instantly. Good cue.
|
||||
|
||||
**The mouth is a smirk** — x −21.93 … 0.00, centred at x = −10.96, stopping on the centreline. A
|
||||
classic character device and a strong asymmetry.
|
||||
|
||||
**The rounds are the best cue and the one safety question.** All four are on the left — Ø11.71 at
|
||||
(−40.82, 7.38), Ø11.71 at (−34.76, 0.58), Ø10.00 at (−29.85, 60.83), Ø2.90 at (−26.70, 65.95) — and
|
||||
the right side is entirely sharp. This is the *most locally readable* cue in the design: the ears
|
||||
differ only by comparison (you must see both to know which is which), whereas a rounded corner tells
|
||||
you "this is the left" from that corner alone, by eye **or by fingertip**. For children assembling by
|
||||
feel that is the cue doing the real work.
|
||||
|
||||
The tension is that "sharp" on a children's part is a hazard, and the obvious safety fix — round
|
||||
everything — destroys the cue. The resolution is not round-vs-sharp but **large-vs-small radius**:
|
||||
keep R≈6 on the left and give the right R≈1. R1 still reads and feels sharp locally, so the cue
|
||||
survives, and the actual edge hazard goes away. That is the one recommendation that outlives the
|
||||
correction.
|
||||
|
||||
**One measurement that does not fit the story:** the outline is off-centre by **0.54 mm** (left reach
|
||||
40.99, right reach 42.07). A deliberate cue should be unmissable; 0.54 mm is invisible. It is
|
||||
probably a by-product of the other features rather than intent — worth a look, not a defect.
|
||||
|
||||
---
|
||||
|
||||
## Two judgement calls, not defects
|
||||
|
||||
**The snout is highest at the nose tip and slopes down toward the brow** — a real bear's muzzle
|
||||
does the opposite. Anatomically it reads more like a beak or a horn than a snout. But mechanically
|
||||
it is the better choice: the nose tip enters the pocket first and does the finding. Keep it if the
|
||||
lead-in matters more than the likeness; flip it if "it must look like a bear" wins.
|
||||
|
||||
**Only the male was supplied**, so the clearance, the fit and the pocket are unassessed. Nothing in
|
||||
this note should be read as a judgement on them.
|
||||
|
||||
---
|
||||
|
||||
## The strategic point, which is the real reason this design is good
|
||||
|
||||
It gives orientation **a name**. "Ears up, nose down" needs no legend, no convention and no
|
||||
documentation. Face recognition is the most robust pattern-matching humans have: it survives low
|
||||
resolution, poor light, partial occlusion and peripheral vision. That is exactly the robustness the
|
||||
abstract ridge key was reaching for, and here it comes for free.
|
||||
|
||||
**One earlier objection does not transfer — noting it only so it is not carried over by mistake.**
|
||||
In §8c of the design doc a female *pocket* measured as visually invisible — flat-shaded, a recess
|
||||
reads as a blank rectangle — and I concluded male/female
|
||||
is the wrong polarity cue. **That was a viewport finding, and it does not apply to a physical part.**
|
||||
Nobody looks into the pocket of a toy; they feel it. For a part in a child's hands, male/female is
|
||||
exactly the right polarity language. The earlier conclusion stands for the on-screen glyph and must
|
||||
not be carried over to this.
|
||||
|
||||
**The one rule to write down now:** the face and the key must never be allowed to disagree. People
|
||||
will trust the face over the mechanics every time. Here they agree — ridge on the centreline, ears
|
||||
up. If the face is ever restyled independently of the key, a user will orient by the bear and be
|
||||
wrong. Tie them permanently, in the model and in whatever generates it.

# Mate connectors: aligning with the mainstream CAD systems
|
||||
|
||||
Research date: 2026-08-05. Written against `orca_cad` / `Snapmaker` at the M8 state
|
||||
(`CadDocument.{hpp,cpp}`, `apply_mate`, `datum_frame`, the `Mate` card in `DesignPanel.cpp`).
|
||||
|
||||
**Brief:** align with the mate-connector concept as the main CAD programs actually implement it,
|
||||
and be simple, unequivocal, unconfusing. Alignment is the organising principle of this document:
|
||||
every recommendation is labelled either **[INDUSTRY]** — do what they all do — or **[DEVIATION]** —
|
||||
we would be departing, here is why and what it costs.
|
||||
|
||||
---
|
||||
|
||||
## 0. The answer in ten lines
|
||||
|
||||
1. Seven systems surveyed. **Five of the seven use the same model**; two are the old world.
|
||||
2. The model: a joint is defined between **two local coordinate frames**, one rigidly attached to
|
||||
each part, plus **one type** naming which DOF stay free.
|
||||
3. The frame is called a mate connector (Onshape), a **joint origin** (Fusion, Inventor), a joint
|
||||
connector (FreeCAD 1.0). Same object, three names.
|
||||
4. **Every one of them expresses every DOF about the frame's Z axis.** One axis, one convention.
|
||||
5. **Five types appear in every frame-based system with identical names and identical DOF**:
|
||||
Fastened/Rigid, Revolute, Slider, Cylindrical, Planar. Ball is in four of five.
|
||||
6. That is not fashion — those are the classical **lower kinematic pairs**. The vocabulary converged
|
||||
because the mechanics converged.
|
||||
7. Our kernel is already on the right side of the line: frame-based, five types, Z-relative,
|
||||
superimpose-then-relax. **The architecture needs no revisiting.**
|
||||
8. Where we are out of step: connectors that are not attached to a body; an origin that can only be
|
||||
a face centroid; no live preview of the two Z arrows; a mate card of abstract dropdowns.
|
||||
9. Where we would knowingly deviate: refusing a second mate per body (no vendor does this — it is
|
||||
forced on us by having no solver) and possibly inverting the default mate direction.
|
||||
10. Biggest single win for the stated goal, and it costs no kernel work: **draw both frames and
|
||||
ghost the result before Confirm.** The convention stops needing to be remembered.
|
||||
|
||||
---
|
||||
|
||||
## 1. The two families
|
||||
|
||||
**Constraint-based ("old CAD").** The user states pairwise *geometric relations* between raw
|
||||
topology — this face coincident with that face, this axis concentric with that axis, this plane
|
||||
parallel at 12 mm. Each relation removes some DOF; a numerical solver satisfies all of them at once.
|
||||
Fully positioning one part typically takes **three or more mates**, and the set can be
|
||||
over-constrained, under-constrained, or satisfiable in several configurations.
|
||||
|
||||
**Frame-based ("mate connectors").** The user places a *local coordinate system* on each part and
|
||||
states **one** relation between the two frames. The relation is not "these surfaces touch" but
|
||||
"these frames coincide, except for the following DOF, which stay free."
|
||||
|
||||
Onshape's help page opens by drawing exactly this line:
|
||||
|
||||
> *"Mates in Onshape are different than mates in old CAD systems. Many assemblies require only one
|
||||
> Onshape Mate between any two instances, as the movement (degrees of freedom) between those two
|
||||
> instances is embedded in the Mate."*
|
||||
|
||||
The frame-based model won for three reasons, all of which matter here:
|
||||
|
||||
- **One mate per pair.** No mental arithmetic about which three constraints add up to a hinge.
|
||||
- **The DOF are declared, not deduced.** A revolute mate *is* one rotation. You do not discover the
|
||||
remaining freedom by dragging.
|
||||
- **It needs no simultaneous solver for the common case.** Frame-to-frame alignment is a matrix
|
||||
composition — precisely what `apply_mate` already does.
|
||||
|
||||
> **Caveat — several vendors ship both, and "align with X" is therefore ambiguous.** **Inventor**
|
||||
> kept its legacy constraints *and* added frame-based Joints in 2012; many Inventor users still build
|
||||
> assemblies entirely with the old constraint stack. **Creo** has placement constraints *and*
|
||||
> Mechanism connections. **FreeCAD** had constraint-based Assembly2/3 add-ons before the frame-based
|
||||
> Assembly workbench shipped in 1.0. So copying "what Inventor does" means copying **one of two
|
||||
> coexisting workflows**. **Onshape and Fusion 360 are the only pure frame-based examples**, and they
|
||||
> are the ones to weight most heavily when the evidence conflicts.

## 2. Field survey — seven systems
|
||||
|
||||
| | Onshape | Fusion 360 | Inventor | FreeCAD 1.0 | Creo | Siemens NX | SOLIDWORKS |
|
||||
|---|---|---|---|---|---|---|---|
|
||||
| **Family** | Frame | Frame | Frame (+ legacy constraints) | Frame (+ legacy add-ons) | Both | Constraint | Constraint |
|
||||
| **Frame object** | Mate connector | Joint origin | Joint origin | Joint connector (`Placement1/2`) | CSYS on `Weld`/`6DOF` | — | — (nearest: **mate reference**) |
|
||||
| **Where it lives** | Part Studio **and** Assembly; in the feature list | Component, inside the joint | Component / inside the joint | Inside the Joint object | Part | — | Part (up to 3 named entities) |
|
||||
| **Origin placement** | Inferred family on hover; `Shift` locks | Discrete **snap points**; `Ctrl` cycles | Snap points + explicit origins | Inferred, previewed on hover | Picked CSYS | Picked entities | Picked entities |
|
||||
| **Orientation control** | Primary axis (Z) + secondary axis; flip + 90° reorient | Flip, angle, offsets | Flip, angle, offsets | `Placement1/2` + `Offset1/2` | CSYS + offset | — | — |
|
||||
| **Type inference** | No — explicit | No — explicit | **Yes — "Automatic"** from picked geometry | No | No | No | Partial (mate reference type) |
|
||||
| **Solver** | Yes, simultaneous — *"order won't affect a Mate"* | Yes | Yes | Yes (Ondsel) | Yes | Yes | Yes |
|
||||
| **Reuse across instances** | **Yes** — a Part Studio connector exists on every instance | Weak | Partial | Per-joint | Interfaces | Product Interface | Mate references auto-mate on insert |
|
||||
|
||||
Three observations that shape everything below.
|
||||
|
||||
- **Every frame-based system reduced the type list by an order of magnitude** relative to SOLIDWORKS
|
||||
(7–13 vs ~25) and lost nothing. That is not simplification-by-omission; it is what happens when the
|
||||
DOF live in the mate instead of being assembled from constraints.
|
||||
- **Every one of them defines its types relative to a single axis.** Slider translates along Z,
|
||||
Revolute rotates about Z, Cylindrical does both, Planar translates in X/Y and rotates about Z.
|
||||
One axis carries the whole vocabulary.
|
||||
- **Onshape alone treats the connector as a first-class, reusable, named object** — and that is also
|
||||
where its worst usability complaints come from (§4).
|
||||
|
||||
---
|
||||
|
||||
## 3. The type vocabulary — cross-system table
|
||||
|
||||
DOF = degrees of freedom left **free**, stated about/along the connector Z.
|
||||
|
||||
| DOF | Onshape | Fusion 360 | Inventor | FreeCAD 1.0 | Creo | **Ours today** |
|
||||
|---|---|---|---|---|---|---|
|
||||
| 0 | Fastened | Rigid | Rigid | Fixed | Rigid / Weld | **Fastened** ✅ |
|
||||
| 1 — rot Z | Revolute | Revolute | Rotational | Revolute | Pin | **Revolute** ✅ |
|
||||
| 1 — trans Z | Slider | Slider | Slider | Slider | Slider | **Slider** ✅ |
|
||||
| 2 — rot + trans Z | Cylindrical | Cylindrical | Cylindrical | Cylindrical | Cylinder | **Cylindrical** ✅ |
|
||||
| 3 — trans XY + rot Z | Planar | Planar | Planar | *(Parallel+Distance)* | Planar | **Planar** ✅ |
|
||||
| 3 — rot XYZ | Ball | Ball | Ball | Ball | Ball | — |
|
||||
| 2 — different axes | Pin slot | Pin-Slot | — | — | Slot / Bearing | — |
|
||||
| 1 — coupled | Screw | — | — | Screw | — | — |
|
||||
| 4 | Parallel | — | — | Parallel | — | — |
|
||||
| other | Tangent, Width, Group | As-built | Automatic | Perpendicular, Angle, Distance, Gears, Belt, RackPinion | General, 6DOF | — |
|
||||
|
||||
**Five types appear in every frame-based system, with the same name and the same DOF.** Those five
|
||||
are the industry's common denominator, and they are exactly `mate_kind` 0–4 as already implemented.
|
||||
Ball is in four of five. Everything past that is a long tail no two vendors agree on.
|
||||
|
||||
### Why the convergence is a fact, not a fashion
|
||||
|
||||
A rigid-body placement is an element of SE(3). A mate leaves some set of relative motions free. For
|
||||
the mate to behave the same throughout its range — for a hinge to be a hinge at every angle — that
|
||||
free set must be **closed under composition**: two allowed motions must compose to an allowed motion.
|
||||
A closed set of motions is a **subgroup** of SE(3).
|
||||
|
||||
The subgroups corresponding to physical surface-on-surface contact are the classical **six lower
|
||||
pairs** (Reuleaux):
|
||||
|
||||
| Pair | Free motion relative to Z | DOF |
|
||||
|---|---|---|
|
||||
| Revolute (R) | rotation about Z | 1 |
|
||||
| Prismatic / slider (P) | translation along Z | 1 |
|
||||
| Helical / screw (H) | coupled rotation + translation | 1 |
|
||||
| Cylindrical (C) | rotation about **and** translation along Z | 2 |
|
||||
| Planar (E/G) | translation in X,Y + rotation about Z | 3 |
|
||||
| Spherical / ball (S) | rotation about X, Y, Z | 3 |
|
||||
|
||||
Plus the two trivial ends: identity (0 DOF — **fastened**) and all of SE(3) (6 DOF — floating, i.e.
|
||||
no mate). Hervé's Lie-subgroup analysis of the displacement group is the standard reference for
|
||||
treating these as the algebraic building blocks of mechanism synthesis.
|
||||
|
||||
**Consequence.** Anything outside this table is either (a) a *composition* needing a solver, or
|
||||
(b) not a joint at all but a *measurement*:
|
||||
|
||||
- Onshape's **Parallel** (4 DOF), **Tangent**, **Width**, **Pin slot**, and FreeCAD's **Distance /
|
||||
Angle / Perpendicular** are constraints, not pairs — their free set is not a subgroup, so they only
|
||||
make sense alongside a simultaneous solver.
|
||||
- **Gear, Belt, Rack-and-pinion** are *relations between two mates*, a different object entirely.
|
||||
- **Screw (H)** is a legitimate lower pair but needs a pitch parameter and is rare in printed parts.
|
||||
|
||||
So the vendors' shared five, the lower pairs, and our `mate_kind` 0–4 are the same list arrived at
|
||||
three ways. **[INDUSTRY] Stop looking for missing types and spend the budget on the connector.**
|
||||
|
||||
---
|
||||
|
||||
## 4. What they all agree on — adopt verbatim
|
||||
|
||||
Deviating from any of these makes an experienced user's intuition *wrong*, which is the operational
|
||||
definition of "confusing".
|
||||
|
||||
**A1 [INDUSTRY] — The connector is a full right-handed frame.**
|
||||
Origin + Z (primary) + X (secondary). Onshape and Fusion expose exactly these two axis controls and
|
||||
nothing else. A point cannot express spin; an axis cannot express clocking.
|
||||
*Status: we comply* — `DatumCoordSys` carries origin/x/y and derives Z.
|
||||
|
||||
**A2 [INDUSTRY] — Z is the joint axis; every DOF is about or along Z.**
|
||||
Revolute rotates about Z. Slider translates along Z. Planar's free plane is normal to Z. Offsets run
|
||||
along Z. This single rule is what makes the system learnable: **one axis to look at, and its meaning
|
||||
never changes.**
|
||||
*Status: we comply* — `mate_offset` along A's z, `mate_angle` about A's z.
|
||||
|
||||
**A3 [INDUSTRY] — Mating superimposes the two frames; the type then relaxes specific DOF.**
|
||||
FreeCAD states it most plainly: *"the second connector is superimposed on the first connector by
|
||||
default and may change its position according to the joint type."* Fastened is not a special case —
|
||||
it is the base case with nothing relaxed.
|
||||
*Status: we comply* — `T = M_A · Rz · Tz · F · M_B⁻¹`, looser kinds relaxing from there.
|
||||
|
||||
**A4 [INDUSTRY] — The connector belongs to a part and moves with it.**
|
||||
Onshape: a connector defined in a Part Studio *"is available for reuse on every instance of that part
|
||||
in every assembly in which it is instanced."* It is part geometry, not assembly geometry.
|
||||
*Status: **violated**.* `CoordSysType::PointWorld` is a bare world XYZ with `X = world X` and no
|
||||
`coordsys_body`. Such a connector does not follow its part. See §6 G1.
|
||||
|
||||
**A5 [INDUSTRY] — Selection order is meaningful and must be visible.**
|
||||
One connector is the reference; the other is driven onto it. Onshape spells out that offsets are
|
||||
measured *"from the second Mate connector selected to the first"*, and that reversing the order
|
||||
flips the sign.
|
||||
*Status: complied with in the data model* (`mate_cs_a` fixed, `mate_cs_b` moves) *but not in the UI* —
|
||||
two dropdowns labelled A and B do not tell the user which part is about to jump.
|
||||
|
||||
**A6 [INDUSTRY] — Flip and re-clock live in the mate dialog, always.**
|
||||
Onshape: *"Click the arrow icon to flip the direction of the primary axis. Click the Reorient
|
||||
secondary axis icon to rotate the secondary axis in 90-degree increments."*
|
||||
*Status: partial.* We have `mate_flip` (Z reversal). We have `mate_angle` as a free number — strictly
|
||||
more powerful than 90° steps, and much worse to *use*: the common case is "it came in a quarter turn
|
||||
out", and typing 90 is a worse gesture than pressing a button.
|
||||
|
||||
**A7 [INDUSTRY] — DOF are shown, not inferred by the user.**
|
||||
Onshape animates each mate's remaining DOF on demand; Fusion and Inventor name the DOF in the type
|
||||
list. Our dropdown text already does this in words ("free spin + axial slide"). Keep it.
|
||||
|
||||
**A8 [INDUSTRY] — Free DOF are preserved from the current placement, not zeroed.**
|
||||
Onshape: a Planar mate aligns the frames *"but they are not restricted to this location with respect
|
||||
to their degrees of freedom."*
|
||||
*Status: we comply* — and it must be *said*, because a Planar mate that leaves the part where it was
|
||||
looks like a mate that did nothing.
|
||||
|
||||
---
|
||||
|
||||
## 5. Where they diverge — who to copy, and why
|
||||
|
||||
### D1 — Where the connector's origin comes from
|
||||
|
||||
| | Behaviour |
|
||||
|---|---|
|
||||
| **Fusion 360** | Discrete **snap points** only: vertex, edge midpoint, face centre, arc centre. `Ctrl` cycles the candidates under the cursor. A circle icon denotes a vertex, a triangle a midpoint. "Between two faces" is a separate explicit option. |
|
||||
| **Onshape** | Infers a *family* on hover — centroid, every vertex, every edge midpoint, every arc centre, the centroids of interior regions (holes, slots), and the virtual sharps of conical faces. `Shift` locks the current candidate. |
|
||||
| **Inventor** | Snap points, plus explicit joint origins for awkward cases. |
|
||||
| **FreeCAD 1.0** | Hovering previews where the connector will land before you commit. |
|
||||
| **Ours** | Always the **face centroid**. No alternative exists. |
|
||||
|
||||
Onshape's richness has a cost its own documentation admits: *"The suggested locations are based on
|
||||
the underlying geometry of the part and changing the geometry will change the location of the Mate.
|
||||
This can be undesirable in certain situations."* On the forum this shows up as connectors that move
|
||||
or break on edit — the classic topological-naming failure. Fusion's discrete set is poorer and far
|
||||
more predictable.
|
||||
|
||||
> **[INDUSTRY] Copy Fusion's candidate *set*.** A small, closed, enumerable set — **face centroid,
|
||||
> vertex, edge midpoint, arc/circle centre** — each drawn before commit, with the card naming which is
|
||||
> in use ("Origin: edge midpoint"). This is our largest expressiveness gap: a face centroid alone
|
||||
> cannot place a hinge pin on a corner boss. It is also the one place where copying the *simpler*
|
||||
> vendor is clearly right.
|
||||
>
|
||||
> **Open sub-choice — how the candidate is chosen.** Three options, in increasing order of magic:
|
||||
> (1) **explicit dropdown** in the card after picking the face — no hover behaviour at all;
|
||||
> (2) **Fusion's `Ctrl` cycling** through candidates under the cursor; (3) **Onshape's hover
|
||||
> inference**. Kimi's independent review argued for (1) on the grounds that hover is exactly where
|
||||
> both vendors' instability complaints originate, and that a dropdown gets ~90% of the expressiveness
|
||||
> with none of the hover-guess debugging. That is a fair reading and (1) is the cheapest to build and
|
||||
> the easiest to make unequivocal. **Recommendation: build (1) first; if hover is added later, let it
|
||||
> *pre-fill the dropdown* rather than silently create an implicit connector** — which also keeps R2
|
||||
> (one kind of connector) intact.
|
||||
|
||||
### D2 — Explicit type, or inferred from the geometry?
|
||||
|
||||
Inventor is the only surveyed system that infers: *"Rotational is selected if the two selected
|
||||
origins are circular. Cylindrical if the two selected origins are points on a cylinder. Ball if
|
||||
points on a sphere. Rigid for all other origin selections."* Onshape and Fusion require an explicit
|
||||
choice.
|
||||
|
||||
> **[INDUSTRY, Inventor] Do both, in Inventor's order.** Infer a *default* type from what was picked,
|
||||
> then show it in an editable control. Inference is what makes the tool feel like it understands the
|
||||
> geometry; the visible, editable result is what keeps it unequivocal. Pure inference with no visible
|
||||
> type is the confusing option; a pure dropdown with no default is the tedious one. This also fits
|
||||
> the Design tab's geometry-first charter exactly: point at a bore, get Revolute offered.
|
||||
|
||||
### D3 — How the Z-direction ambiguity is resolved
|
||||
|
||||
This is the specific failure the brief is aimed at. A former IT trainer stated it precisely on the
|
||||
Onshape forum:
|
||||
|
||||
> *"There is always the risk that users will build their own conceptual models of how software works
|
||||
> which may not match the designer's concept. The result is usually a poor user experience and many
|
||||
> mistakes… for a good (say) Fixed mate to occur do the Z axes of the two mates have to be pointing
|
||||
> in the same direction… Alternatively, should they be facing each other?"*
|
||||
|
||||
He is asking the right question and **no vendor's documentation answers it.** Onshape's own advice —
|
||||
*"if the behavior is not what you expected, try flipping the primary and/or secondary axis"* — is
|
||||
trial and error. This is a gap in the industry, not a convention to copy.
|
||||
|
||||
> **[INDUSTRY, method] Resolve it with live preview, not documentation.** FreeCAD previews the
|
||||
> connector on hover; Onshape and Fusion both draw the frames. Draw **both** Z arrows the moment the
|
||||
> second connector is picked, and ghost the resulting placement *before* Confirm. The convention then
|
||||
> never has to be remembered because it is on screen.
|
||||
>
|
||||
> **[DEVIATION, optional] Name the two cases in the user's words** rather than in axis-speak:
|
||||
> "the two faces come together" vs "the axes run the same way". No surveyed vendor does this — they
|
||||
> all ship a flip arrow. It is a small, low-risk improvement on the state of the art, and it is
|
||||
> separable from the default-direction question in §8 D1.
|
||||
|
||||
### D4 — Named, reusable connectors on the part
|
||||
|
||||
Onshape: connectors created in the Part Studio are reused on every instance in every assembly.
|
||||
SOLIDWORKS' **mate reference** reaches the same end by another route: up to three named entities
|
||||
(primary/secondary/tertiary) baked into the part so it auto-mates on drag-and-drop — and a *named*
|
||||
mate reference seeks out a matching name on insertion. That naming trick is how a library of
|
||||
fasteners assembles itself.
|
||||
|
||||
> **[INDUSTRY] Out of scope now, but do not preclude it.** Give connectors a stable, user-visible
|
||||
> name at creation. One string today; expensive to add once documents exist in the wild.
|
||||
|
||||

|
||||
|
||||
## 6. Confusion catalogue
|
||||
|
||||
Documented ways real implementations confuse people. Each is a requirement in disguise.
|
||||
|
||||
**C1 — Which way does Z point?** See D3. If a user has to ask once, they will mis-predict a hundred
|
||||
times.
|
||||
|
||||
**C2 — The roll is unspecified.** Aligning Z leaves one rotation about Z undetermined. Something must
|
||||
pin it, and if that something is world-derived, the frame does not rotate with its part. **This
|
||||
codebase shipped exactly this bug** (`en4`): a face-only connector took Z from the face
|
||||
normal but X from `coordsys_x_hint`, a world constant, so Fastened and Slider claimed to lock an
|
||||
orientation the frame could not see. Fixed 2026-07-26 by deriving X from the face's own first usable
|
||||
edge — but note the fix's own caveat: *"replaying an older document whose face-only connector fed a
|
||||
mate can now place that body differently."* Roll conventions are load-bearing, and changing one is a
|
||||
document-format change.
|
||||
|
||||
**C3 — The origin drifts.** See D1.
|
||||
|
||||
**C4 — Implicit and explicit connectors are not the same thing.** On the Onshape forum, implicit
|
||||
connectors are reported to change their query structure when a feature is edited and re-accepted, and
|
||||
are unusable in places explicit ones work. Two things called by one name that behave differently is a
|
||||
permanent tax.
|
||||
|
||||
**C5 — Which part moves?** A frame alignment is asymmetric. If the UI does not say which frame is
|
||||
driven, the user finds out by watching the wrong part jump.
|
||||
|
||||
**C6 — Which direction is a positive offset?** Onshape measures *"from the second Mate connector
|
||||
selected to the first"* — the sign depends on pick order, and swapping the picks flips it. Documented
|
||||
behaviour, documented surprise.
|
||||
|
||||
**C7 — One intent, several mates.** The SOLIDWORKS failure: expressing "this shaft is in this hole,
|
||||
resting on this shoulder" as three constraints, then discovering the solver picked the mirror
|
||||
configuration. Frame-based systems fix this by construction; the requirement is not to reintroduce it.
|
||||
|
||||
**C8 — Degenerate frames.** A circular face has no usable in-plane edge direction; a cylinder seam
|
||||
projects to nothing; a picked edge parallel to Z gives a zero cross product. `datum_frame` handles all
|
||||
three with fallbacks — the requirement is that a fallback be *visible*, because a silent fallback is
|
||||
C2 wearing a different hat.
|
||||
|
||||
**C9 — Order dependence without a solver.** Onshape can say *"Onshape solves Mates simultaneously so
|
||||
order won't affect a Mate."* A system that composes transforms in tree order cannot say that. Two
|
||||
mates driving one body means the second wins and the first is a lie on screen.
|
||||
|
||||
**C10 — Mirrors and patterns.** A mirrored instance has a left-handed frame. Blindly mirroring a
|
||||
connector gives a frame whose Z still points "out" but whose handedness flipped, so every rotation
|
||||
runs backwards. Cheap to handle now, miserable to retrofit.
|
||||
|
||||

|
||||
|
||||
## 7. Requirements
|
||||
|
||||
Labelled **[INDUSTRY]** (what the frame-based systems do) or **[DEVIATION]** (we would depart).
|
||||
|
||||
### Definition
|
||||
|
||||
**R1 [INDUSTRY] — A mate connector is a frame attached to exactly one body.** No body, no connector.
|
||||
*Test:* creating a connector without a body is rejected at creation, not at mate time.
|
||||
→ **`CoordSysType::PointWorld` violates this.** It is a datum wearing a connector's name.
|
||||
|
||||
**R2 [INDUSTRY] — One kind of connector, not two.** No "implicit" connector that behaves differently
|
||||
from an explicit one. If hover inference is offered, hovering *creates* an ordinary connector.
|
||||
*Why:* C4. *Test:* everything that accepts a connector accepts any connector.
|
||||
|
||||
**R3 [INDUSTRY] — A mate names exactly one subgroup of free motion.** Fastened (0), Revolute (1),
|
||||
Slider (1), Cylindrical (2), Planar (3), optionally Ball (3). *Why:* §3. *Test:* every type's free
|
||||
set is closed; no type is "A and also B".
|
||||
|
||||
### Orientation
|
||||
|
||||
**R4 [INDUSTRY] — Everything is about Z. Say so once, in the UI.** *Test:* no mate parameter refers
|
||||
to any other axis.
|
||||
|
||||
**R5 [DEVIATION] — Z is the outward material direction, and mates default to FACING.**
|
||||
A mate would drive B's Z onto **−A's Z** by default, so picking two faces that should touch makes
|
||||
them touch with no options changed. *Why:* it is the whole of C1.
|
||||
**Cost and caveat:** this inverts today's default (`mate_flip=false` currently *aligns*), and I could
|
||||
not establish from any vendor's documentation what their default actually is — the forum question in
|
||||
D3 went unanswered precisely because it is undocumented. So this is marked a deviation on the honest
|
||||
grounds that **I cannot prove the industry agrees with it.** If D3's live preview lands first, the
|
||||
default matters much less, because the user sees the outcome before committing. See §9 D1.
|
||||
|
||||
**R6 [DEVIATION] — Name the two directions; do not ship a boolean called "flip".**
|
||||
`Direction: Facing | Aligned`. Every surveyed vendor ships a flip arrow instead. A boolean requires
|
||||
remembering what unticked means; two named values do not. Low risk, small improvement on the state of
|
||||
the art.
|
||||
|
||||
**R7 [INDUSTRY] — Roll is picked, or a stored quarter turn. Never world-derived.**
|
||||
X from a referenced edge or in-plane direction; failing that, a deterministic body-attached seed, with
|
||||
**Rotate 90°** offered as a stored integer 0–3 on top (this is Onshape's "reorient secondary axis",
|
||||
A6). *Why:* C2 and the world-constant bug this project already shipped. *Test:* rotate the parent
|
||||
body by any angle; the connector's X rotates with it — *this test already exists* ("a face-only frame
|
||||
rotates with its body").
|
||||
|
||||
**R8 [INDUSTRY] — A degenerate roll is reported, not absorbed.** *Test:* a connector on a full
|
||||
cylindrical face reports "roll undefined — pick a direction" rather than silently taking a fallback.
|
||||
|
||||
### Placement
|
||||
|
||||
**R9 [INDUSTRY, Fusion] — Origin comes from a small closed set of named candidates.**
|
||||
**Face centroid, arc/circle centre, edge midpoint, vertex.** Four. Each stored as
|
||||
`(kind, topological reference)` and resolved at rebuild. *Why:* D1. *Test:* the stored kind is visible
|
||||
in the card; a rebuild either resolves it or raises an error.
|
||||
|
||||
**R10 [INDUSTRY] — An unresolvable reference is an error, never a silent relocation.**
|
||||
*Test:* delete the referenced face; the mate reports "connector A: face not found" and the body stays
|
||||
where it was.
|
||||
|
||||
### Semantics without a solver
|
||||
|
||||
**R11 [DEVIATION] — A body is driven by at most one mate. The second is refused.**
|
||||
**No surveyed system does this** — they all have solvers and all accept many mates per body. It is
|
||||
forced on us by tree-order composition: a second mate on the same body silently overrides the first
|
||||
and the screen shows a configuration satisfying only one stated intent (C9). *Test:* creating a
|
||||
second mate whose moving body already has one is rejected, naming the existing mate.
|
||||
This is the single largest departure in this document. See §9 D4.
|
||||
|
||||
> **A tempting misreading, checked and rejected.** It is easy to find the claim that Onshape mandates
|
||||
> *"exactly one Mate between any two instances"*, which would make R11 an industry agreement rather
|
||||
> than a deviation. **The Onshape page does not say that.** It says *"**Many assemblies require only**
|
||||
> one Onshape Mate between any two instances"* and then lists, as an explicit remedy, *"**Use more
|
||||
> than one Mate if necessary.**"* One mate per pair is Onshape's *typical case*, not its rule. R11
|
||||
> remains a deviation and must be justified on our own architecture, not on theirs.
|
||||
|
||||
**R11a [DEVIATION] — The refusal list.** With no solver, these are unsupportable and must be refused
|
||||
rather than half-done: a second mate on an already-driven body; cycles (A→B, B→A); closed loops
|
||||
(A→B, A→C, B→C); relations *between* mates (gear, belt, rack-and-pinion, screw coupling); **joint
|
||||
limits**, which nothing can enforce without a solver; and **dragging a body to exercise a free DOF**,
|
||||
which requires keeping the body on the allowed manifold. Motion analysis and animation follow from the
|
||||
same lack. *Requirement:* none of these may appear in the UI as something that half-works.
|
||||
|
||||
**R12 [DEVIATION] — The mate graph is an acyclic forest rooted at fixed bodies.** A body reached by
|
||||
no mate is fixed; cycles are refused. Same root cause as R11. *Test:* A→B, B→A rejected at creation.
|
||||
|
||||
**R13 [INDUSTRY] — Free DOF are preserved from the current placement, and the user is told.**
|
||||
Behaviour already matches Onshape (A8); the telling does not. *Test:* the card for any type with
|
||||
DOF > 0 says which motions remain and that dragging exercises them.
|
||||
|
||||
**R14 [INDUSTRY] — State what mirroring does to a connector.**
|
||||
*Checked in the code:* `datum_frame` ends with a Gram-Schmidt forcing a right-handed frame
|
||||
(`ds.x = Y.cross(Z)`), so a connector resolved on a mirrored body comes out **right-handed, not
|
||||
mirror-imaged**. Z follows the mirrored face's outward normal, X follows a mirrored edge, handedness
|
||||
is re-imposed. Defensible — a mate on the mirrored part still turns the way its type says — but it
|
||||
means a mirrored sub-assembly is *not* the mirror image of the original in its rotation sense.
|
||||
*Requirement:* document it and pin it with a test. *Why:* C10.
|
||||
|
||||
### Feedback — the part that actually removes confusion
|
||||
|
||||
**R15 [INDUSTRY] — Before Confirm, the card answers four questions in words.** Which body moves;
|
||||
which way Z points on each connector; how many DOF remain; what the offset is measured from.
|
||||
|
||||
**R16 [INDUSTRY] — Draw both frames live, with Z distinguishable, and ghost the result.**
|
||||
Two triads with Z rendered differently from X/Y (length, arrowhead, colour). *Why:* D3 — the fastest
|
||||
way to make a convention unequivocal is to show it. *Test:* both Z directions are readable in a
|
||||
screenshot.
|
||||
|
||||
**R17 [INDUSTRY] — Show the DOF budget per body.** "Body 2: 1 of 6 DOF free (rotation about Z)."
|
||||
The most educational readout in any assembly system, and free to compute here — the type *is* the DOF
|
||||
count. *Test:* the number changes when the type changes.
|
||||
|
||||
**R18 [DEVIATION] — Refuse loudly and name the alternative.** Where something is out of scope (a
|
||||
second mate, a tangency, a gear ratio), say what is unsupported and what to do instead. Vendors do not
|
||||
need this because their solvers accept the input. *Test:* no refusal message ends without a suggested
|
||||
next action.

## 8. Minimal specification, and gap analysis
|
||||
|
||||
### The connector
|
||||
|
||||
```
|
||||
MateConnector
|
||||
body int required, ≥ 0 (R1)
|
||||
origin_kind enum FaceCentroid | ArcCentre | EdgeMidpoint | Vertex (R9)
|
||||
origin_ref topo ref face / edge / vertex index on that body
|
||||
z_source implied by origin_kind: face normal, arc axis, edge tangent
|
||||
roll_ref topo ref optional in-plane edge; else deterministic seed (R7)
|
||||
roll_quarters int 0..3 stored quarter turns on top of the seed (R7, A6)
|
||||
flip_z bool reverse Z at the connector
|
||||
name string stable, user-visible (D4)
|
||||
```
|
||||
|
||||
`flip_z` is a property of the **connector**, chosen once when it is made — not a per-mate
|
||||
afterthought. Keeping connector-flip and mate-direction separate is what stops the "which flip do I
|
||||
tick?" question.
|
||||
|
||||
### The mate
|
||||
|
||||
```
|
||||
Mate
|
||||
kind enum Fastened | Revolute | Slider | Cylindrical | Planar [| Ball] (R3)
|
||||
fixed connector A — its body does not move
|
||||
moving connector B — its body is driven (A5, C5)
|
||||
direction enum Facing | Aligned (R5, R6)
|
||||
offset mm along A's Z, measured A → B — state this in the label (C6)
|
||||
angle deg about A's Z (R4)
|
||||
```
|
||||
|
||||
Within one field of what exists.
|
||||
|
||||
### Gaps against today
|
||||
|
||||
Source of record: `CadDocument.hpp:26,247-252,298-310`; `CadDocument.cpp:1669` (`datum_frame`),
|
||||
`:2961` (`apply_mate`), `:1302` (`add_mate`); `DesignPanel.cpp:2671-2709` (the Mate card).
|
||||
|
||||
| # | Gap | Severity | Ref |
|
||||
|---|---|---|---|
|
||||
| G1 | `PointWorld` connectors are not attached to a body and their X is a world constant | **High — data model** | A4/R1 |
|
||||
| G2 | Origin is always the face centroid; no vertex / edge-midpoint / arc-centre snap | **High — expressiveness** | D1/R9 |
|
||||
| G3 | No live preview of the two Z arrows or of the resulting placement | **High — this is the brief** | D3/R16 |
|
||||
| G4 | Mate card is two abstract dropdowns; nothing says which body moves | High — charter + A5 | R15 |
|
||||
| G5 | No joint-type inference from the picked geometry | Medium — feel | D2 |
|
||||
| G6 | `add_mate` validates nothing — no one-mate-per-body, no cycle check | Medium | R11/R12 |
|
||||
| G7 | No `Ball` type | Low | §3 |
|
||||
| G8 | Re-clocking needs a typed angle; no 90° step control | Low, cheap | A6/R7 |
|
||||
| G9 | Degenerate roll falls back silently | Low | C8/R8 |
|
||||
| G10 | Connectors have no stable user-facing name | Low now, expensive later | D4 |
|
||||
|
||||
**Already aligned — do not "fix" these:** the five types and their DOF; the frame definition (A1);
|
||||
Z as the joint axis (A2); superimpose-then-relax (A3); the fixed/moving asymmetry in the data model
|
||||
(A5); DOF wording in the type list (A7); free-DOF preservation (A8); right-handed frames under mirror
|
||||
(R14); and `en4`'s fix, which put roll derivation on the body where it belongs (C2).
|
||||
|
||||
**The pattern worth naming: the kernel is in good shape and the concept is under-explained.** Half the
|
||||
requirements here are wording and drawing, not geometry. The two real engineering items are R9 (origin
|
||||
candidates) and R11/R12 (the mate-graph rules).
|
||||
|
||||
### Expensive-to-retrofit decisions — get these right in the data model now
|
||||
|
||||
Changing any of these after documents exist in the wild costs a migration, not an edit.
|
||||
|
||||
1. **Topological reference stability.** Storing raw face/edge indices is brittle — editing a body
|
||||
renumbers faces. Either persistent topology IDs, or store the named origin *kind* plus a
|
||||
deterministic search that re-finds the same geometric intent on rebuild. The latter is cheaper and
|
||||
probably sufficient here; it is also what makes R10's "error, never silent relocation" enforceable.
|
||||
2. **Connector ownership** (R1). Remove `PointWorld` or bind it to a body. Do this first.
|
||||
3. **Mate direction semantics** (R5/D1). Inverting the default rewrites the meaning of every saved
|
||||
mate.
|
||||
4. **Roll representation** (R7). "First usable edge" is better than world-X but still fragile. Store
|
||||
an explicit roll reference plus quarter turns.
|
||||
5. **Coordinate convention** — Z = joint axis, X = roll reference. Changing this after release
|
||||
invalidates every mate.
|
||||
6. **Units** — offset in mm, angle in degrees. Never change.
|
||||
7. **Mirror handedness** (R14) — document the decision, do not let it stay an accident.
|
||||
8. **Flat body index vs. a component tree.** Mates currently reference bodies in a flat vector. If
|
||||
**sub-assemblies** are ever in scope, mates must reference nodes in a tree instead. Retrofitting
|
||||
this is painful and it is the one item on this list not already implied elsewhere in the document —
|
||||
**decide now whether nested assemblies are in scope.**
|
||||
9. **Serialization field semantics.** Adding fields is easy; redefining `mate_flip` or
|
||||
`coordsys_x_hint` is not.
|
||||
10. **The one-mate-per-body rule** (R11). Enforce at creation. Relaxing it later by adding a solver is
|
||||
straightforward; allowing many mates now and discovering later that they silently conflict is not.
|
||||
|
||||

|
||||
|
||||
## 8b. The visual shape of the connector — polarity and verse
|
||||
|
||||
Researched separately (2026-08-05) by downloading and **looking at** the vendors' own figures, not
|
||||
by reading their prose. Files kept alongside this document in `doc/design/mate-connectors/`.
|
||||
|
||||
### What the systems actually draw
|
||||
|
||||
**Onshape** — verified from `planarfacemateconnectors.png`, `cylindricalmateconnectors.png`,
|
||||
`linearedgemateconnectors.png`, `mateconnector-planarpoints.png`, `matepointiconLG.png`:
|
||||
|
||||
> **A small circle with one quadrant filled, plus three short coloured axis arms (X red, Y green,
|
||||
> Z blue).**
|
||||
|
||||
Three parts, each doing one job:
|
||||
|
||||
| Element | What it says |
|
||||
|---|---|
|
||||
| The **circle** | "I am a frame, and this is my XY plane." |
|
||||
| The **filled quadrant** | **The roll.** The shaded sector is the +X/+Y quadrant. |
|
||||
| The **coloured arms** | The three axis directions, Z distinguished by colour. |
|
||||
|
||||
The quadrant is the cleverest part of the whole design and it is easy to miss. The figure
|
||||
`matepointreorientsecondaryaxis.png` shows three connectors side by side with the quadrant in three
|
||||
different rotations — **it is the live readout of "reorient secondary axis in 90° increments" (A6).**
|
||||
One glyph element makes the otherwise-invisible clocking visible, and makes the 90° button's effect
|
||||
legible before you commit. The toolbar icon `matepointiconLG.png` is that same circle-with-a-quadrant,
|
||||
so the symbol is consistent from toolbar to viewport.
|
||||
|
||||
Candidate snap points, before you choose one, are drawn as **plain small white dots** on the model
|
||||
(clear in `mateconnector-planarpoints.png`: dots at every corner and edge midpoint). Candidate and
|
||||
committed are deliberately different weights — dots propose, the circle-and-triad commits.
|
||||
|
||||
**FreeCAD 1.0** — verbatim from the wiki: *"Connectors are local coordinate systems and are marked by
|
||||
a symbol with three axes (X, Y, Z) and a circle representing the XY-plane."* Same core as Onshape —
|
||||
circle plus triad — **without** the quadrant.
|
||||
|
||||
**Fusion 360** — the joint origin glyph, plus a documented icon language for *candidates*: *"A circle
|
||||
denotes a vertex, and a triangle denotes a midpoint."* Shape encodes what kind of point it is.
|
||||
|
||||
**Convergent core:** *circle for the XY plane + coloured triad*. Onshape alone adds the roll quadrant.
|
||||
|
||||
### What none of them draw — and it is exactly what was asked for
|
||||
|
||||
**Nothing in any vendor's glyph says which connector is the reference and which one is about to
|
||||
move.** Both ends of a mate are drawn identically. That is confusion C5 ("which part moves?") left
|
||||
unsolved in the visual language, and it is why the honest recommendation earlier was a live ghost —
|
||||
the ghost compensates for a glyph that does not carry the information.
|
||||
|
||||
So the two things asked for split cleanly, and only one of them is solved upstream:
|
||||
|
||||
- **Verse** (*verso* — which way it points): **solved**. Z has a colour and a direction.
|
||||
- **Polarity** (which end receives, which end inserts; who is anchored, who travels): **unsolved
|
||||
everywhere.** This is open ground, and getting it right is a genuine improvement rather than a
|
||||
deviation to justify.
|
||||
|
||||
### Our starting point
|
||||
|
||||
**We draw nothing.** `resolve_datum_coordsys()` (`CadDocument.cpp:1749`) has exactly one consumer in
|
||||
the entire tree — `McpControl.cpp:1310`, the agent socket. A mate connector is today visible only to
|
||||
a program. The glyph is unbuilt, so there is no migration cost to designing it properly now.
|
||||
|
||||
### Proposed glyph: the magnet
|
||||
|
||||
Adopt Onshape's proven core, then add the missing polarity with a metaphor that carries its own
|
||||
instructions.
|
||||
|
||||
```
|
||||
▲ solid cone on +Z ONLY ← verse
|
||||
|
|
||||
────●──── ← the disc = XY plane, ● = exact origin
|
||||
▨ quadrant filled ← roll / clocking, steps 90°
|
||||
```
|
||||
|
||||
**Rule 1 — verse: draw +Z and never −Z.** A single stem with a cone head, on the positive side only.
|
||||
No stem below the disc. A double-headed axis is the one thing that guarantees the question gets asked;
|
||||
an arrow that exists on one side only cannot be misread. Length is asymmetric on purpose.
|
||||
|
||||
**Rule 2 — roll: keep Onshape's quadrant.** Filled sector = the +X/+Y quadrant. It rotates in 90°
|
||||
steps with the reorient control (A6/R7). This is aligned *and* it is the only in-glyph answer to
|
||||
"where is X?", which matters because Fastened and Slider lock the clocking.
|
||||
|
||||
**Rule 3 — polarity: solid cone travels, open collar receives.**
|
||||
- The **driven** connector (B, on the body that will move) draws a **solid filled cone** — the plug.
|
||||
- The **fixed** connector (A) draws an **open ring / hollow cone outline** — the socket.
|
||||
|
||||
Same silhouette, so they read as a matched pair; opposite fill, so which one is about to jump is
|
||||
answerable at a glance and without a legend. Plug-into-socket is the one mechanical metaphor every
|
||||
user of this tool already has in their hands.
|
||||
|
||||
**Rule 4 — the pair reads as a magnet.** Draw a dashed line joining the two origins the moment both
|
||||
are picked. Two poles, one field line. And because a magnet's north seeks a south, **"facing" becomes
|
||||
the self-evident default** — which quietly settles open decision D1 (§9) on visual grounds rather than
|
||||
on a convention nobody can look up. If the glyph looks like a magnet, nobody has to be told that two
|
||||
faces which touch have opposed normals.
|
||||
|
||||
**Rule 5 — three states, three weights.**
|
||||
|
||||
| State | Drawing |
|
||||
|---|---|
|
||||
| **Candidate** (hover) | small dot only — Onshape's white dots; shape may encode kind, Fusion-style |
|
||||
| **Picked** | full glyph: disc + quadrant + cone |
|
||||
| **Degenerate roll** (C8/R8) | the quadrant is drawn **hollow/hatched** — "roll undefined, pick a direction" |
|
||||
|
||||
That last row is worth the trouble: it turns R8 from a message nobody reads into a mark you cannot
|
||||
miss, and it costs one branch in the renderer.
|
||||
|
||||
**Rule 6 — do not reuse the existing triad.** The bed-centre world triad
|
||||
(`DesignCanvas.cpp:65`, `set_axes_at_bed_center`) and the move gizmo are already three-coloured arrows.
|
||||
The connector must not be a fourth set of RGB arrows or the viewport becomes unreadable. The disc and
|
||||
the quadrant are what distinguish it; keep the arms short, and consider drawing only Z on the
|
||||
committed glyph, with X/Y implied by the quadrant.
|
||||
|
||||
### Built and judged in the viewport, not in a mock
|
||||
|
||||
The browser mock that first accompanied this section was the wrong instrument and its proportions
|
||||
were meaningless: **every gizmo in this codebase is sized in SCREEN PIXELS** via `upp = 1/zoom`
|
||||
(`render_shell_gizmo` uses `15.0 * upp`, `render_hole_gizmo` `9.0 * upp` for its cube). A connector
|
||||
is a symbol, not a part — it must not shrink with the model. Nothing about that is visible in SVG.
|
||||
|
||||
The glyph was therefore implemented and driven on the rig. Screenshots: `g-0*.png`, left in the workspace `artifacts/shots/` and not moved into the repo.
|
||||
Five findings, none of which a mock could have produced:
|
||||
|
||||
**F1 — Three axis arms lose to one.** Rendered side by side (`ORCA_CAD_GLYPH=A` vs default), the
|
||||
Onshape-style RGB trio crowds a 22 px disc: the arrowheads are as large as the disc, they bury the
|
||||
gold quadrant, and at an oblique angle the three heads pile into a coloured smudge. Worse, **it is
|
||||
indistinguishable from the move gizmo and the bed triad**, which are already RGB arrow trios in this
|
||||
viewport. One-sided Z wins on evidence, not taste. (`g-01-zoom.png` vs `g-02-zoom.png`.)
|
||||
|
||||
**F2 — Polarity works, and colour does more of the work than fill.** A filled blue head against an
|
||||
open grey outline head is readable instantly at 22 px (`g-03-zoom.png`). But the fill difference is
|
||||
the *second* cue; the colour split carries it. Keep both — fill survives greyscale and colour-blind
|
||||
palettes, colour survives small size.
|
||||
|
||||
**F3 — Depth off floats, depth on tears.** With `GL_DEPTH_TEST` off, connectors on faces pointing
|
||||
*away* from the camera still drew their discs over the solid, so the part looked covered in frames
|
||||
that were really on its back. Turning depth on fixed that and immediately caused **z-fighting**: the
|
||||
disc is exactly coplanar with its face, and came out as a broken dotted arc. The fix is depth **on**
|
||||
plus a sub-pixel lift along Z (`0.7 * upp`), scaled by `upp` so it never becomes a visible gap on
|
||||
zoom-in. Both failure modes are in the images (`g-03` torn, `g-04` clean).
|
||||
|
||||
**F4 — The quadrant is the first thing to die at a grazing angle.** On a face seen nearly edge-on the
|
||||
disc foreshortens to a sliver and the fan collapses into a blob (`g-01-zoom.png`, lower-right glyph).
|
||||
The roll is exactly the information that is hardest to read when you most need it. Not yet solved —
|
||||
see the open item below.
|
||||
|
||||
**F5 — Roll-undefined in red is too loud.** It works, but it makes the *least* important connector
|
||||
the most eye-catching thing on screen. Amber, or the same grey with a hatched quadrant, is enough.
|
||||
|
||||
Also surfaced while testing, and unrelated to the glyph: `add_mate` accepted a mate between two
|
||||
connectors **on the same body**, which is meaningless, and duly transformed the body relative to
|
||||
itself. Concrete instance of gap G6.
|
||||
|
||||
**Still untested:** a true grazing view (the view-cube click missed), a connector on a curved face,
|
||||
and behaviour when a connector overlaps the move gizmo. F4 is the open design question — the disc may
|
||||
need to billboard its *quadrant* while keeping the disc in-plane, which is a compromise no surveyed
|
||||
vendor makes and which should be tried before being adopted.
|
||||
|
||||
### What this costs
|
||||
|
||||
A renderer for `resolve_datum_coordsys()` — which does not exist and has to be written whatever glyph
|
||||
is chosen — plus one dashed line and three fill states. No kernel work. It is the same piece of work
|
||||
as G3 (live preview), and doing them together is what makes the mate card honest.
|
||||
|
||||

|
||||
|
||||
## 8c. The "faceted ridge dome" proposal — built, rendered, judged
|
||||
|
||||
A colleague proposed replacing the flat disc with an **asymmetric low-poly solid**: a faceted
|
||||
prismatic wedge with a dominant longitudinal ridge that **slopes** from a tall steep back to a long
|
||||
shallow front, plus a male protrusion / female pocket pair with a 0.2 mm clearance.
|
||||
|
||||
It was built rather than discussed. `faceted_ridge_key.scad` (this folder) (6 vertices, 7 faces),
|
||||
verified as a closed manifold, exported through OpenSCAD, and flat-shaded from five directions with
|
||||
`render_key.py` / `render_stl.py`. Sheets: `rk-sheet.png`, `cmp-sheet.png`.
|
||||
|
||||
### The verdict: the shape is right, the male/female polarity cue is not
|
||||
|
||||
**It solves F4, decisively.** The grazing view — where the flat disc dies, its quadrant collapsing to
|
||||
a blob — is the view where this shape is *most* legible: the tall back and long shallow front are
|
||||
unmistakable in silhouette. At a grazing angle the silhouette IS the information, and this solid's
|
||||
silhouette is maximally informative there. That is a real, evidence-backed win over what is currently
|
||||
in the code.
|
||||
|
||||
**Down the mating axis (+Z) it also reads well**, which matters because that is the natural viewing
|
||||
direction when you are looking at a face you intend to mate.
|
||||
|
||||
**One degenerate view, and it is not the one I predicted.** I expected the ±X views (along the ridge)
|
||||
to be silhouette-ambiguous, resolved only by shading. Wrong: front and back are clearly *different* —
|
||||
the front shows several facets, the back is a **single flat featureless triangle**. So they are not
|
||||
confusable, but the view from directly behind the tall end tells you nothing about roll or slope.
|
||||
A second blind spot remains untested: from below the base, where the protrusion is hidden behind its
|
||||
own face.
|
||||
|
||||
**The female half fails, and much harder than expected.** Rendered with flat shading and no outlines —
|
||||
the honest test, since a viewport draws no black edges — a recessed pocket is *invisible*: iso and
|
||||
grazing show a plain block with a hairline; straight down the axis shows a **completely blank
|
||||
rectangle**. The interior faces are lit almost identically to the top face and are occluded by the rim
|
||||
from most angles. As a polarity cue, male/female therefore works in exactly one direction and returns
|
||||
nothing in the other.
|
||||
|
||||
> **Conclusion: do not overload shape with all three jobs.** Let the solid carry **verse and roll**,
|
||||
> where it is excellent, and carry **polarity on a second channel** — colour plus the filled/open head
|
||||
> that already tested well at 22 px (F2). Drawing the fixed connector as an outline/wireframe of the
|
||||
> same solid is the variant worth trying; drawing it as a pocket is not.
|
||||
|
||||
### Two premises in the brief are wrong
|
||||
|
||||
**"Avoid curved surfaces to optimise rendering computations / rapid mesh processing."** Not a reason
|
||||
for a viewport glyph. There are 2–20 connectors on screen, the renderer pushes `GLModel` triangles
|
||||
directly, and it performs no CSG or mesh processing at all. **The real argument for flat facets is
|
||||
legibility**: hard normals give distinct value steps between adjacent facets, and the renders confirm
|
||||
that is exactly what makes the shape readable from an arbitrary angle. Keep the constraint, fix the
|
||||
justification. (For a *printed* part the original justification is sound for a different reason: flat
|
||||
facets slice without the stair-stepping a tessellated curve produces.)
|
||||
|
||||
**"0.2 mm clearance for smooth mechanical mating."** Meaningless for a glyph. A symbol mates with
|
||||
nothing, and every gizmo here is sized in screen pixels via `upp`, so a millimetre tolerance has no
|
||||
referent. This is the strongest signal that **the brief was written for a physical printed part**,
|
||||
not for a viewport symbol — as are "scannable" and "mechanical mating". See the open question below.
|
||||
|
||||
### Two defects the build caught that discussion would not have
|
||||
|
||||
1. **The flank quads are not planar.** Written as `[0,3,5,4]` and `[1,4,5,2]` the base edge and the
|
||||
ridge edge are skew, so the four corners do not share a plane — my own first draft asserted the
|
||||
opposite in a comment. Left as quads, the tessellator picks the fold direction, the "flat facet"
|
||||
promise is broken by an unspecified crease, and two exporters can disagree about the shape. Fixed
|
||||
by triangulating explicitly (7 faces, Euler 6 − 11 + 7 = 2).
|
||||
2. **The pocket punched through its own plate.** A 4.5 mm key against a 3 mm demo plate gives a
|
||||
through-hole, not a pocket. Minimum stock = height + clearance + pocket depth + a wall.
|
||||
|
||||
Also worth recording: the first female render was misleading because the debug renderer outlined
|
||||
*every* triangle, so a flat top face triangulated by CGAL looked like a faceted dome. The instrument
|
||||
lied before the geometry did. Conclusions were only drawn after outlines were removed.
|
||||
|
||||
### Second opinion, and the one disagreement worth resolving
|
||||
|
||||
Kimi reviewed the proposal independently and **rejected it for the viewport**. It agreed on the two
|
||||
wrong premises, agreed the female pocket is unreadable, and added the useful framing that a
|
||||
screen-constant symbol and a model-constant part feature are two different design spaces that cannot
|
||||
be served by one geometry. It also noted correctly that there is **no single scalar** that removes
|
||||
ambiguity from every view: you need one asymmetry in the base plane (for top-down roll) and one out
|
||||
of plane (the ridge slope, for front/back). Our base is scalene, so it has both.
|
||||
|
||||
Its central objection was numeric and testable: *"at 22 px with 6–8 facets each facet is 3–7 px wide,
|
||||
that is at the aliasing limit … minimum useful size is roughly 32–48 px, which is not compatible with
|
||||
a 22 px screen-constant symbol."* My own renders were ~300 px, so the claim was unaddressed by my
|
||||
evidence and would have killed the concept if true.
|
||||
|
||||
**Rendered at 22, 32 and 48 px (`size-test.png`), it is false for this shape.** At 22 px all three
|
||||
views still read: the grazing view shows the tall back and shallow front unmistakably, and the
|
||||
down-axis view keeps a strong dark/light split. The reason Kimi's arithmetic does not apply is that
|
||||
this solid presents only **four or five large facets with high value contrast**, not eight small ones —
|
||||
the silhouette does most of the work, and silhouettes survive downsampling far better than facet
|
||||
detail does.
|
||||
|
||||
*Honest limit on that result:* the test renderer has no anti-aliasing, no perspective, one directional
|
||||
light, and no background. Readable at 22 px against white is not the same as readable at 22 px on top
|
||||
of a shaded gold part next to the move gizmo. That case still needs the rig.
|
||||
|
||||
**Where I do not follow Kimi:** its recommendation is to **billboard** the existing flat glyph so it
|
||||
never turns edge-on. That kills F4 by construction, but a billboarded frame cannot show the frame's
|
||||
orientation *in place* — which is the entire reason the disc is a disc and not a dot — and it is what
|
||||
no surveyed CAD system does; Onshape, Fusion and FreeCAD all draw the frame in the geometry. Worth
|
||||
prototyping as an option, not worth adopting on argument.
|
||||
|
||||
### Open question for Tommaso
|
||||
|
||||
**Is this a viewport glyph or a printable alignment feature?** The vertex logic is identical either
|
||||
way; only the units and the clearance change, and the `.scad` file states both readings. But the
|
||||
answer decides whether `clr`/`depth` are real millimetres or meaningless, and whether the geometry
|
||||
scales with the model or stays screen-constant. The brief's own language points at "physical", the
|
||||
conversation it arrived in points at "glyph".
|
||||

## 9. Decisions for you
|
||||
|
||||
**D1 — Invert the default direction to Facing?** [DEVIATION, R5]
|
||||
It changes the meaning of every stored document containing a mate. Options: (a) invert and migrate,
|
||||
writing `direction=Aligned` where `mate_flip` was false; (b) invert only for new mates and store
|
||||
`direction` explicitly from now on. (b) is safer and costs one field. Note this project has taken one
|
||||
such semantic hit knowingly before — the `en4` fix — and the golden fixture survived, so the
|
||||
migration path is a known quantity. **If G3 (live preview) lands first, this matters much less.**
|
||||
|
||||
**D2 — How far to take origin candidates?** [R9]
|
||||
Four kinds is the Fusion-aligned recommendation. Two (face centroid + arc centre) would cover "sit on
|
||||
a face" and "go down a hole" — most printed-part assembly — at a third of the work. Where do you want
|
||||
to stop?
|
||||
|
||||
**D3 — Ball mate: in or out?**
|
||||
In four of five frame-based systems, so including it is the aligned choice. Out is defensible for
|
||||
printable mechanical parts. Cheap either way — align origins, leave orientation free. Kimi's review
|
||||
argued **out**: a true ball joint is hard to print and hard to use without a roll reference, and a
|
||||
Fastened connector at the ball centre approximates it.
|
||||
|
||||
**D3a — Should Planar be dropped?** [dissent worth recording]
|
||||
Kimi's independent review recommended **removing Planar** and shipping four types, on the grounds that
|
||||
"slide on a flat surface" is rarely how printed mechanisms work — you usually want a rail or a hinge —
|
||||
and that Planar is the type most likely to confuse a user who expected "put this flat on that" and got
|
||||
a part free to slide. It further ranked the honest minimum as **three**: Fastened, Revolute, Slider,
|
||||
with Cylindrical useful and decomposable.
|
||||
**I do not agree, and the reason is alignment.** Planar appears in every frame-based system surveyed,
|
||||
it is a genuine lower pair, it is already implemented and tested, and removing it is a document-format
|
||||
change made in exchange for nothing. The confusion Kimi names is real but it is a *feedback* problem —
|
||||
it is exactly what R17 (show the DOF budget) and R13 (say that free DOF are preserved) exist to fix.
|
||||
Recorded here because it is a legitimate reading of the same evidence and the call is yours.
|
||||
|
||||
**D4 — Is refusing a second mate per body acceptable?** [DEVIATION, R11 — the big one]
|
||||
It is the honest consequence of having no solver, and it is what makes the tool predictable. But **no
|
||||
mainstream system behaves this way**, so it is the point where an experienced user's intuition will
|
||||
break. It means a part cannot be constrained by two independent relationships — "in this hole *and*
|
||||
resting on this shoulder" must be expressed by placing one connector correctly rather than by two
|
||||
mates. If that trade is unacceptable, the answer is a solver, and the scope of this document changes
|
||||
entirely.
|
||||
|
||||
There is a strong argument that the trade is not merely acceptable but *correct for this product*:
|
||||
the Design tab lives inside a slicer, and most of its users are positioning parts for printing rather
|
||||
than building working mechanisms. For layout-and-export, tree-order composition is genuinely enough,
|
||||
and adding a solver to look like Onshape would buy complexity nobody asked for. The rule to publish is
|
||||
then simple and defensible: **one mate per moving body, acyclic, no relations between mates** — with
|
||||
R18's loud refusals carrying the honesty.

# Does the connector pair let two hosts sit COPLANAR, or does it hold them apart?

# The male's flat back is the plane Y=0 and all its relief rises to +Y. So Y=0 is the natural
|

# mating datum: everything the male adds lives on one side of it. The test below builds two dummy
|

// - all dimensions must become SCREEN PIXELS scaled by upp = 1/zoom, because every gizmo

// in that viewport is screen-constant and must not shrink with the model;
|

// - "low-poly for rendering performance" is not a real reason at ~2-20 glyphs per frame.
|
||||
// The real reason to keep flat facets there is LEGIBILITY: hard normals give distinct
|
||||
// value steps between facets, and that is what lets a 22-px solid read as an oriented
|
||||
// object instead of a grey blob.
|

// The vertex logic above is identical under both readings. Only the units and the clearance

# from a block. Working on the real solid rather than re-modelling the bear is the whole point —

# the pocket is then exactly complementary by construction, including every deliberate asymmetry.
|

#
|

# The offset uses join=2 (Intersection), which extends the adjacent planes and meets them at a

# sharp corner. For a faceted part that is the correct join: the arc join would round every convex
|

# edge and blunt the very cues the design depends on.

# THE MALE'S NATIVE FRAME: the flat back is the plane Y=0 and the relief rises to Y=+17.27.

# X and Z carry the face (83.34 x 66.69). The frame is kept exactly as supplied so that male and

# female drop into the same assembly without anyone having to re-orient one of them.
|
||||
# Insertion is therefore along +Y, and the pocket must OPEN on the Y=0 plane.
|
||||
#
|

# A first version of this script assumed the relief ran along +Z, built the block around the wrong
|

# axis, and produced a sealed cavity with no way in. It passed a "male does not intersect female"

"""Reduce the bear face to the fewest marks that still read at glyph size — wi3z.

Geometry comes from bear_outline.json, which extract_outline.py pulled off the supplied male

B-rep's back plate: the outer wire IS the silhouette, the inner wires are the two eyes and the
|
||||
muzzle opening. Nothing here is traced by eye.

The glyph is drawn IN the connector's plane, so a grazing view foreshortens it along one axis by
|

sin(elevation) — exactly what collapsed the disc's roll quadrant to 3 pixels at 10 deg. Every

candidate is therefore rendered at three elevations as well as three pixel sizes.
