Windows minwindef.h defines legacy 'near'/'far' as empty macros, so MSVC
mangled `auto near = ...` (C2513) and every near(...) call (C2679/C2678 on
Vec2d). gcc/clang were unaffected, so only the Windows build failed.

gcc reads "\x10cad..." as one escape (c/a/d are hex digits → 0x10CAD > 255).
Split the string literal so the \x10 escape terminates. clang let it slide;
gcc (Linux/Windows CI) errored and blocked the OrcaSlicer build.

- Keyboard shortcuts (Onshape-style, three scoped layers): feature tools on
Shift+letter, 2D sketch tools on single letters (in-sketch), view/nav on
single letters (out-of-sketch). Dispatched via the DesignPanel CHAR_HOOK.
- View toggles: P = origin planes, A = world axis triad (render_view_helpers).
- Section view (non-destructive): a single horizontal clip that hides half the
model to inspect inside, showing only the solid remaining half (no ghost).
Left-panel "Section View" button or X toggles it; PageUp/PageDown move the
plane; "Flip Section" button or F shows the opposite half. Never a body/Cut.

Six fixes to the Design tab, all live-verified on :10:
- Datum-plane re-pick: wxEVT_CHOICE on m_draw_plane re-planes the live sketch
- Delete-feature dismisses its lingering settings card (on_delete_feature)
- Revert rotation-orbit regression (no feed_bodies/reload on close_tool)
- Sketch undo/delete via focus-independent CHAR_HOOK (Ctrl+Z/Y, Delete)
- Fix undo hang: reset_autoedit() clears dangling auto-edit sequence
- Titled value fields: each inline dim field shows its role (Width, Height,
Radius, Angle, Length, Side, Distance, Major, Minor)

Closes the gizmo-parity gap (bd snaporca-4h5): the five solid features that were
card-only now give in-canvas feedback like their siblings.
Draft — angle-arc drag gizmo (clone of the Revolve gizmo): once a side face is
picked, a cyan arc anchored at the face centroid shows the taper angle; drag the
tip or type the angle, the live ghost tapers with it. Axis = world +Z (the neutral
pull direction), clamped [-89, 89].
Cut — plane offset-arrow + cutting-plane rectangle (clone of the Shell arrow, adds
a wire rectangle in the cut plane sized to the target body bbox). The arrow drags
the signed offset along the plane normal; the rectangle rides at the cut position;
the ghost splits live. (Also covers bd snaporca-1gh / snaporca-mmr.)
Boolean / Sweep / Loft — operand highlighting (new by-index highlight infra):
- Boolean tints the target body teal-green and the tool body orange (per-index
body tint added to the DesignCanvas GLVolume colour loop + set_operand_bodies).
- Sweep tints the profile sketch cyan and the path sketch magenta.
- Loft tints every selected profile sketch green.
Sketch tints reuse the DisplaySketch overlay via a feature-index -> colour map
(sketch_hl_color); DisplaySketch struct unchanged. All self-gate by active tool
and clear on close_tool.
Wiring mirrors the existing gizmo pattern 1:1 (m_*_active / render_* / set_* /
clear_* / update_* in refresh_preview / DesignCanvas passthroughs / render dispatch
+ on_mouse drag branch). Both forks; DesignSketchTool.{cpp,hpp} + DesignCanvas.hpp
+ DesignPanel.hpp byte-identical across forks. Built clean on both. Draft, Cut and
Boolean highlight live-verified on :10; Sweep/Loft sketch tint is code-complete and
build-clean (visual check pending — needs hand-drawn profile/path sketches).

Sketch dimension labels — now identical to the Prepare/Preview Measure gizmo:
- draw_text repurposed to draw_dim_label: white ImGui text in a translucent-white box,
mirroring GLGizmoMeasure::render_dimensioning exactly (push_common_window_style sets the
text colour, BringWindowToDisplayFront, imgui_internal.h).
- ROOT-CAUSE FIX: world_to_screen_px multiplied two Eigen Transform3d objects
((proj * view).matrix()); a projection is not affine so Eigen mangled it -> garbage screen
coords, so labels never appeared. Now proj.matrix() * view.matrix() like Measure. (That
helper was previously [[maybe_unused]] dead code, never exercised.)
- Leaders: offset clear of the sketch line (no longer coincident with the geometry), single
point-to-point dimension line + arrows, neutral colour, width 0.6 -> 0.2.
- dim_text appends mm/in on linear dims (angles keep the degree sign).
New Design + delete:
- New "New Design" button wipes the whole document (confirm dialog) — the clear-all the
per-row Delete can't give. CadDocument::clear() now also clears bodies + display_body_meshes
(it left them stale, so solids lingered after a clear).
- on_delete_feature: a Body-row selection now shows a helpful hint (bodies are recomputed
results with no directly-removable feature) instead of silently doing nothing.
Feature tree: auto-fits its content (refresh_tree clamps height 1..9 rows, scrolls past),
instead of a fixed 140px block.
i18n (Design tab pinned English, per the UX contract):
- Restore the lost #undef _L / #define _L(s) wxString::FromUTF8(s) override atop DesignPanel.cpp;
wrap all ~54 dropdown options in _L so the single lever governs them. feature_type_name left
untranslated (machine-facing MCP JSON).
UX: per-card Value Confirm/Cancel buttons removed — the single ribbon action bar owns value
confirm/cancel via an m_value_cont guard in tool_confirm/tool_cancel. "needs a body" status
messages unified.
Both forks; DesignSketchTool.{cpp,hpp} + CadDocument.cpp byte-identical across forks. Built
clean; New Design / feature-delete / rotation / tree auto-fit live-verified on :10.

Dimensions (uniform with Prepare/Preview):
- Repurpose DesignSketchTool::draw_text -> new draw_dim_label that renders each
sketch dimension as the exact Prepare "Measure" gizmo label: white ImGui text
in a translucent-white box, positioned via the existing world_to_screen_px
projection inside the active ImGui frame. All 29 label call sites convert with
no churn; the bespoke Hershey vector font is retired.
- dim_text appends mm/in on linear dims (angles keep the degree sign).
- Placed-dimension leaders simplified to a single point-to-point line + arrows in
a neutral colour (no extension lines), matching the Measure look.
i18n (Design tab pinned English, per the UX contract):
- Restore the lost "#undef _L / #define _L(s) wxString::FromUTF8(s)" override atop
DesignPanel.cpp so one lever de-translates the whole tab, ending the half-EN/IT
state. Wrap all ~54 dropdown options in _L so the single lever governs them.
- feature_type_name left untranslated (it feeds the MCP JSON, machine-facing).
UX consistency:
- Remove the per-card Confirm/Cancel buttons from the Value card; the single ribbon
action bar now owns value confirm/cancel via an m_value_cont guard in
tool_confirm/tool_cancel (one confirm surface, per contract).
- Unify the eight divergent "needs a body" status messages to one template.
Both forks; DesignSketchTool.{cpp,hpp} byte-identical across forks. Built clean.

Reconstruction is no longer box-only. Five new actions, all thin
wrappers over existing CadDocument::add_* (the same kernel the GUI
calls): revolve (sketch -> add_revolve), fillet/chamfer targeted at a
measured edge id from query_topology, hole (add_hole), and boolean
(union/subtract/intersect over two bodies). extrude and revolve also
accept an optional closed profile=[[x,y],...] -> add_sketch_profile,
the Measure->Build bridge: feed a measured/sliced contour straight back.
Shared helpers plane_from / bool_from / profile_from. Each action is
transactional (checkpoint -> add -> recompute -> undo on failure ->
refresh) and returns post-state. Live-verified: fillet, chamfer (clean
edge), hole, profile-extrude (L), revolve (ring), boolean union (3->2
bodies). MCP method catalogue now 13.

Add the Build-input and Validate ends of the reverse-engineering loop.
import_step loads a STEP as native B-rep bodies (the reference part to
measure), reusing the GUI Import path (read_step_solids -> Import
features -> recompute). validate_against compares a body to a reference
({step:path} | {body:id}) and reports volume delta %, bbox delta, and
centroid offset via OCCT GProp + Bnd_Box — the RE skill's actual
acceptance metric (the "scarto %"); surface-deviation heat-map is the
upgrade path.
With this the full Understand -> Measure -> Build -> Validate loop is
live: 8 methods (describe_tools/describe_scene/query_topology/measure/
slice_body/import_step/validate_against/extrude). Verified: import a STEP
then validate body vs same STEP = 0.0%% delta / 0.0mm offset.

The "evidence" half of the reverse-engineering loop — read-only
perception that turns a body into measured numbers. query_topology
lists faces (centroid/normal, cylinder radius+axis when round) and
edges (length, circle radius); measure returns distance (and angle when
both refs have a direction) between two {face|edge|point} refs;
slice_body cross-sections a body by a base plane at an offset and
returns world polylines (sections-as-evidence). All reuse GeometryEngine
topology accessors; slice_body adds one BRepAlgoAPI_Section call.

Zero-dependency Python stdio MCP server that exposes the app's control
socket as first-class MCP tools. Builds the tool list live from the
app's own describe_tools reply (introspection drives the schema), and
forwards tools/call to the Unix socket. Falls back to the slice-1 tool
set and reports a clear error when the app socket is down — never
crashes. Registered via a workspace .mcp.json (ssh stdio to the build
host); activates on the next session.

Predispose the Design tab to run under an external MCP agent. New
McpControl.{cpp,hpp} embeds a line-delimited JSON-RPC 2.0 server over a
Unix domain socket, off unless env SNAPORCA_MCP is set. Requests are
marshalled onto the wx main thread and run through the SAME CadDocument
kernel the GUI uses, via two thin DesignPanel hooks (mcp_doc /
mcp_after_change) — no parallel engine.
Slice-1 methods: describe_tools (introspection -> the bridge builds tool
schemas), describe_scene (feature tree + per-body bounding boxes), and
extrude (centred rectangle sketch -> new solid). Every op returns its
full post-state. POSIX-only; Windows compiles to a no-op.

Fusion 360 .f3d uses Autodesk's closed ShapeManager kernel — no offline
reader exists and it is input-only even in Autodesk's own cloud API, so
native import/export is infeasible. Intercept .f3d at priv::load_files

pointing the user to export STEP from Fusion, then load any other files

Add an "Export STEP…" button to the Design panel that writes every body to a
.step file as native B-rep (not mesh).
- CadDocument::export_step: compound all bodies (applying their per-body Move
display transform so the STEP matches what Commit ships) and write via OCCT
STEPControl_Writer (AsIs). Full error handling incl. OCCT Standard_Failure.
- DesignPanel::on_export_step: bake any open preview, wxFileDialog save, export
at the displayed body positions, status feedback.
Kernel write path verified with a standalone OCCT box->STEP->readback check
(1 solid, non-null) against the same OCCT build.

Boolean features can now be re-edited from the feature tree (op, target/tool
body, keep-tool, fuzzy tolerance), funnelling through the same replace_feature
path as every other editable feature.
- on_edit_feature: route CadFeatureType::Boolean to the Boolean card.
- load_feature_into_dialog: populate the Boolean card from the saved feature.
- populate_body_choices(as_of_feature): when re-editing, list the bodies as they
existed just before the boolean (replay the recipe truncated to that slot) so a
consumed tool body still appears and the saved target/tool selections round-trip
instead of collapsing to one entry.

Port of the snaporca CAD work to the mainline fork.
- Onshape default planes (XY/XZ/YZ) at the bed centre (transparent, labelled);
modeling origin unified to the bed centre (CadDocument::modeling_origin);
world-axis triad moved to the bed centre on the Design canvas only.
- Datum plane: clickable ghost-plane base pick + draggable offset arrow.
- Slot: dims reassessed to inter-centre distance / radius / angle; fixed the
duplicate cap-arc radius quote.
- Hole: 3D cube move-handle on the face; binds to the face on the first click;
decluttered side-distance construction lines.
- Thread: derive the M spec (diameter/pitch/depth) from a picked cylindrical
surface or circular edge (GeometryEngine::circle_of_edge); fuse the helical
ridge onto the existing body; MakePipeShell fixed-binormal sweep (uniform, no
twist) + self-intersection/param guards.

Mirror of snaporca-cad 75045ff. Re-editing an Extrude spawned a NEW misplaced
box: build_candidate() rebuilt the feature from live tool state, but GUI
extrudes store their profile as `entities` (sketch_ref = -1) which the edit
card never restores, so the candidate had an empty profile and replace_feature
swapped in a degenerate extrude. Fix: when editing, seed the candidate from the
feature being edited and skip add-time structural re-derivation (profile source,
up-to-face, target body); the card still overrides scalar params.

proving recompute() replays the whole timeline, so editing any feature (not
just the last) rebuilds downstream: mid-timeline extrude edit -> fillet
rebuilds; first-feature sketch edit propagates the chain; the same survives
serialize_recipe()/deserialize_recipe(); a sketch->extrude->hole->chamfer
chain rebuilds hole+chamfer on a mid-edited extrude. All 3 pass (34 assertions,
Catch2 v3). on_edit_feature edits the tree-selected feature at any position
(13/16 types); Import/Boolean/Cut get a status message instead of a silent
no-op (full dialogs = follow-up snaporca-nu9).

Mirror of snaporca-cad f3b665b. DesignCanvas had ~38 call-sites doing
`set_as_dirty(); render()` directly, tagged "llvmpipe: force repaint" —
software-GL workarounds from the headless :10 test box. On hardware GL this
bypasses the dirty/refresh cycle and burns frames outside the paint event.
Funnel all 38 through a new request_repaint() helper that branches on the
cached GL renderer string: hardware GL gets set_as_dirty()+wxGLCanvas::Refresh()
(render() runs inside the paint cycle), software GL keeps the direct render(),
undetected backend takes the safe direct path. Behaviour on the llvmpipe :10
box is byte-identical; hardware GL invalidates the canonical editor way.

Mirror of snaporca-cad 0f53a09. DesignPanel.cpp pinned every _L() to
wxString::FromUTF8 via a TU-local #define, hardcoding English and bypassing
the gettext catalog — a hard review-blocker for upstream (OrcaSlicer ships
~20 locales). Remove the override so the 463 _L("...") call-sites route
through the real Slic3r::GUI::I18N::translate (wxGetTranslation). All args
are string literals; untranslated strings fall back to the source msgid, so
English is byte-identical while other locales now translate when .po entries
exist. xgettext scans source text, so .pot extraction is unaffected.

Mirror of snaporca-cad ad822bf. The earlier mirror (2c0140afb9) implemented
persistence in the PrusaSlicer 3mf.cpp, but the GUI saves/loads projects via the
BBS-native backend (store_bbs_3mf / load_bbs_3mf), so the recipe was never
written to nor read from GUI-saved projects.
- bbs_3mf.cpp: BBS_CAD_RECIPE_FILE = "Metadata/SnapOrca_cad.bin"; writer
_add_cad_recipe_file_to_archive (called after layer-height in store_bbs_3mf);
reader branch in _load_model_from_file's metadata dispatch loop (iterate +
iequals on m_filename — mz_zip_reader_locate_file does not work on these
archives).
- Plater.cpp: load_files carries the Model-level cad_recipe onto q->model().
- test_3mf.cpp: [3mf] test asserting store_bbs_3mf embeds the recipe entry
byte-for-byte (read back via miniz, Catch2 v3).
Verified on behemoth: libslic3r_tests + the new [3mf] BBS test pass; orca-slicer

Dual-fork mandate: port the parametric-recipe 3MF persistence from
snaporca-cad commits ed19eac+147e1c4 so a saved project reopens with the
editable CAD feature tree, not just the baked mesh.
Shared kernel/format/GUI (identical to snaporca-cad):
- CadDocument serialize_recipe/deserialize_recipe (cereal BinaryArchive,
versioned) + CadFeature split save/load + imported_solid<->BRep string.
- Model::cad_recipe carried through 3MF zip entry Metadata/SnapOrca_cad.bin
(writer + binary-verbatim reader branch).
- DesignPanel on_commit() stamps the recipe; on_tab_shown() rehydrates a
loaded project via load_recipe() (deserialize -> feed_bodies + refresh_tree).
Mainline-only adapters (no snaporca-cad counterpart — Catch2 v3 vs v2):
- tests/libslic3r/test_caddocument.cpp: <catch2/catch_all.hpp> +
`using Catch::Approx;` (v3 scopes Approx under Catch::).
- tests/libslic3r/CMakeLists.txt: register test_caddocument.cpp (the
original CAD port had left it out of the test build).
Verified on behemoth (snaporca-deps toolchain): libslic3r_tests clean;
[CadDocument] 17/18 (only the pre-existing tangent-to-circle SIGABRT fails,
identical to snaporca-tkz); K1 serialize round-trip + version-reject pass
(13 assertions); new [3mf] "CAD recipe blob survives a 3mf save/load cycle"
passes byte-for-byte; orca-slicer GUI links clean (186/186, DesignPanel.cpp
