Adds SketchEngine::make_bridge (4-pole cubic Bezier, G1-tangent to Line/Arc
endpoints, straight-line fallback for other types) emitted as the existing
BSpline SketchEntity — no new geometry type, no serialized-field change, golden
recipe fixture untouched. CadDocument::add_bridge appends it (non-parametric,
index-validated, throws on bad refs). MCP `bridge` method mirrors action_project.
4 new [CadDocument][bridge] tests; full kernel suite green (76 cases, 1280 asserts).

The construction flag was already honored (excluded from the extrude wire in
SketchEngine.cpp, participates in the solver, and serialized) but the existing
"construction line excluded" test was a false tripwire: its construction line
ran corner-to-corner inside the square, so the bbox was unchanged whether or not
the line was excluded.
- Strengthen that test: the construction line now runs (-30,0)->(30,0) outside
the profile, so an exclusion regression breaks the closed wire / bbox.
- Add a serialize/deserialize round-trip test asserting construction survives.
- Lock the flag on-disk: add Sketch_Ctor to the golden fixture with a real edge
+ a construction edge, and assert both flags survive the binary recipe.
Test-only; no kernel change. Recipe version stays 2 (construction was already a
serialized field). Suite: 72 cases / 1246 assertions green.

Onshape-style "Use / Convert entities": pick edges (or a whole face) of an
existing solid and get sketch geometry projected onto a target plane, then
extrude/revolve/edit it like any sketch. Parametric: apply_project re-derives
the feature's entities from the source body on every recompute, so editing the
source updates the projection.
Line edges -> Line entities (exact); circles/arcs whose plane is parallel to
the sketch plane -> Circle/Arc (exact); everything else (incl. non-parallel
circles that project to ellipses) -> sampled Line chain.
Append-only: new enum value Project + project_source_body/project_edges/
project_face fields at the end of save/load; recipe version stays 2. Recompute
loop made non-const solely so apply_project can write back f.entities.
Suite 67->71 cases, 1178->1229 assertions, RC=0. Fixture 25493->26835 B.

Split-by-face reuses the existing Cut feature rather than adding a new type:
two appended fields (cut_face_body, cut_face) let apply_cut derive the cut
plane from a picked face via SketchPlane::from_face when cut_face >= 0,
otherwise it keeps using the base `plane`. cut_offset / cut_flip still apply
along the derived normal, so the same square-wire split machinery handles
both cases. add_split_by_face() is the convenience entry point; MCP gains a
`split` method (body / face_body / face / keep_upper / keep_lower).
Serialization stays append-only — cut_face_body, cut_face appended to
save/load, recipe version unchanged at 2.
Tests: the previously-missing both-halves plane cut (keep_upper && keep_lower
=> two bodies whose volumes sum to the original), split-by-face via a
top-face plane offset into the interior, keep-upper-only, and a round-trip.
Golden fixture regenerated with a GoldenSplit cut-by-face feature and exact
field-value assertions. Suite 63 -> 67 cases, 1119 -> 1178 assertions.

Pick a face of an existing body, offset it by a wall thickness along its
normal, and append the resulting thin solid as a new body. Onshape-parity
Tier-2 item; the kernel had Shell (hollow a whole solid) but no way to turn
a single face into a plate.
Kernel: CadFeatureType::Thicken, add_thicken()/apply_thicken() as a
body-level op next to Transform/Mirror. The picked face is wrapped in a
TopoDS_Shell and offset via BRepOffsetAPI_MakeThickSolid::MakeThickSolidBySimple;
the result is orientation-normalised to positive volume (same convention as
apply_mirror). Serialization stays append-only — thicken_face,
thicken_thickness, thicken_flip appended to save/load, recipe version
unchanged at 2.
MCP: `thicken` method (body/face/thickness/flip) plus the missing
feature_type_name() case.
Tests: 6 new [CadDocument] cases (plate volume within 1%, flip direction,
bad face id, zero thickness, fuse-with-source, round-trip). Golden fixture

Until now move and rotate lived only in the GUI as m_body_xform, a display
transform. That made them a correctness hole, not a missing tool: a moved body
recomputed and booleaned at its ORIGINAL position, and the move was not in the
recipe at all, so it vanished on save/reload. Only export_step consulted the
transform, which is why the discrepancy stayed hidden.
CadFeatureType::Transform makes it a real feature: rotate angle_deg about
xf_axis through xf_pivot, then translate by xf_translate, applied to the target
body with BRepBuilderAPI_Transform. xf_copy=true keeps the source and appends
the transformed body instead of mutating in place, which covers Onshape's
Transform/copy in the same feature.
Rotation is composed before translation (trsf = tr * rot) so the pivot means
what a user expects — the point the body turns about, not a point that then
drifts with the translation. A rotation with a degenerate axis is refused
rather than silently skipped; a zero angle skips the rotation entirely so a
pure move needs no axis at all.
The decisive test is not the bbox arithmetic but "moved body participates in a
later boolean at its new position": two coincident boxes, one moved to partial
overlap, fused. The fused volume must be strictly greater than one box (the
move took effect in the kernel) and strictly less than both (they still
intersect). With a display-only transform the first assertion fails.
Serialization stays append-only; recipe version unchanged at 2. Golden fixture
regenerated with a GoldenTransform feature carrying distinctive literals so a
field reorder shows up as obviously wrong values. Also fills in the Helix arm
of feature_type_name(), missing since the helix commit.
Kernel suite 51 -> 57 cases, 985 -> 1054 assertions, green.

Adds CadFeatureType::Helix — the missing input for Sweep. Sweep already
existed but could only follow a sketch, so springs, coils, augers and
non-standard-pitch threads were unreachable. Helix + the existing Sweep now
gives all of them with no further work.
Built the OCCT way: a 2D line on a Geom_CylindricalSurface (Geom_ConicalSurface
when helix_taper_deg != 0) turned into an edge and lifted to 3D with
BRepLib::BuildCurves3d — a true analytic helix, not a sampled polyline, so a
swept spring is smooth rather than faceted. The axis is the plane normal
through the plane origin, matching how Revolve and Plane already work.
Sweep's path resolution is widened to accept either a Sketch (unchanged
behaviour) or a Helix, and rejects anything else with a clear error. Helix
itself is skipped in route_feature and recompute — like the datum features, it
produces no body and exists to be consumed.
Invalid input is refused rather than approximated: non-positive radius or
pitch, negative height, a turn count above 10000 (which would hang OCCT), and
a taper that would drive the radius negative before reaching the top all fail
with a specific error.
Serialization: helix_radius/pitch/height/left_handed/taper_deg appended at the
very end of both save and load, identical order, after the coordsys block.
SNAPORCA_CAD_RECIPE_VERSION stays 2; Helix is appended to the end of
CadFeatureType. Golden fixture regenerated with distinctive literals and
field-value assertions; all pre-existing assertions pass unchanged.
Tests assert analytic values. The one that actually proves it is a helix and
not a circle or a spiral: arc length of r=5 pitch=2 height=10 measured with
BRepGProp::LinearProperties against 5*sqrt((2*pi*5)^2 + 2^2), WithinRel 1e-3.
Plus bounding box (2r in X and Y, height in Z), the conical top radius, the
left-handed winding compared at equal parameter, and the integration test:
a circle r=1.5 swept along a 5-turn helix gives one valid solid of ~1115 mm^3
(WithinRel 0.1 — pipe sweeping is not exact).
MCP: `helix` method registered in describe_tools().
Ported from snaporca 6cdc6b5459. Two fork-specific adjustments: the two new
error-message assertions use Catch2 v3's ContainsSubstring (v2's Contains does
not exist here), and the golden fixture is copied rather than regenerated
because this fork cannot be compiled locally — make_golden_doc_v1() is
byte-identical across both forks, so the blob is provably the same.

Adds CadFeatureType::Axis and ::CoordSys — reference geometry that produces
no solid, modelled on the existing Plane datum feature.
Axis construction methods (AxisType): TwoPoints, FaceNormal,
CylinderCenterline, PlaneIntersection, AlongEdge. The centreline case is the
useful one: it gives a real axis through an existing hole or boss.
Coordinate systems (CoordSysType): PointWorld and FaceAndDirection. The
latter Gram-Schmidts the picked references, so the stored frame is
orthonormal even when the user's X hint is not perpendicular to the face
normal; the third axis is derived by cross product rather than stored, so it
cannot drift out of sync.
Revolve and pattern are deliberately NOT rewired to consume these — this
commit adds the reference geometry only and changes no existing behaviour.
Serialization: all axis_*/coordsys_* fields appended at the very end of both
CadFeature::save and load, identical order, after mirror_keep_original.
SNAPORCA_CAD_RECIPE_VERSION stays 2; Axis and CoordSys are appended to the
end of CadFeatureType so existing type ordinals are unchanged. Golden fixture
regenerated with distinctive non-default literals and field-value assertions
for every new field; all pre-existing assertions pass unchanged.
Tests assert analytic values: two-point axis direction exactly +Z with unit
length, cylinder centreline collinear with Z and on the true axis, parallel
planes fail cleanly, and the Gram-Schmidt frame is orthonormal to 1e-9 with
X x Y == Z. Degenerate input (identical points) fails with a non-empty error
rather than producing NaNs.
MCP: `axis` and `coordsys` methods registered in describe_tools().
Ported from snaporca 242d4efecb. The golden fixture is copied rather than
regenerated because this fork cannot be compiled locally (Eigen 5.0.1 vs the
build image's 3.3); make_golden_doc_v1() is byte-identical across both forks,
so the two fixtures are provably the same blob.

Adds CadFeatureType::Mirror: reflect a target body about a plane using
gp_Trsf::SetMirror + BRepBuilderAPI_Transform. BooleanMode::New keeps the
mirrored copy as its own body (mirror_keep_original decides whether the
source survives); BooleanMode::Add fuses it back into the source, so an
overlapping mirror does not double-count volume.
Serialization: mirror_keep_original is appended at the very end of both
CadFeature::save and load (append-only contract). The mirror plane reuses
the existing `plane` member and the body selector reuses `target_body`,
as Cut already does. Golden fixture regenerated at the current
SNAPORCA_CAD_RECIPE_VERSION = 2; the existing field-value assertions all
still pass unchanged, and the reorder tripwire was re-verified after
regeneration (swapping draft_face/draft_angle in `load` alone still
fails the golden test).
Tests assert analytic values: mirrored volumes equal (8000 each) with the
reflected centroid, Add on a non-overlapping asymmetric body gives exactly
2x volume, Add across an intersecting plane gives strictly less than 2x,
and an invalid body index fails cleanly with a non-empty error.

CadFeature::save/load is append-only by contract, and ~20 planned features
each append fields. The existing roundtrip test cannot police that: it writes
and reads with the same code, so any self-consistent ordering passes. Only a
blob written by older code and stored on disk can detect that the format moved.
The first attempt at this test passed while the defect was present. I proved
it by swapping draft_face (int) with draft_angle (double) in both save() and
load() -- a genuine byte-layout change -- and it still reported 613 assertions,
exit 0. It asserted only derived geometry: body count, per-body volume, feature
types. The golden document had no Draft feature, so those fields sat at their
defaults, the reorder scrambled values nothing read, and the recomputed solids
came out byte-identical.
So the fixture now asserts the DATA, not what the data produces:
- make_golden_doc_v1() builds 22 features across 14 types (Draft, Shell,
Revolve, Pattern, Cut, Hole, Chamfer, Fillet, Extrude taper/symmetric,
Thread, Sweep, Loft, Boolean, Plane) with distinctive non-default literals
(draft_angle 7.25, shell_thickness 1.375, revolve_angle 217, pattern_count 5)
so a reorder produces visibly wrong values rather than swapped defaults.
- Layer 1 reads the committed blob with raw cereal and asserts field by field,
independent of recompute, so a geometry regression cannot mask a format break.
- Layer 2 keeps the geometry checks as a separate concern.
Verified to trip, twice, by deliberate breakage rather than by assertion:
draft_face <-> draft_angle -> draft_face reads 1075642368 (0x401d0000),
the high half of double 7.25
revolve_angle <-> revolve_axis -> revolve_angle reads 0.0, not 217.0
Both revert clean to 758 assertions / 30 cases.
Also scoped the "regenerate the fixture" hint to the feature-count check only.
It was in scope for every assertion in the block, so a detected reorder told
you to run [.regen] -- which would bake the corrupted layout in as the new
golden and permanently disarm the test. A guard must not advise disabling
itself.

Ported from snaporca f9e0f99bcb. The patch needed fuzz: this fork's copy of
test_caddocument.cpp carries a Catch2 v3 include, a `using Catch::Approx`, and
an extra [Deviation] case appended after line 1611 -- exactly where these hunks
land. Verified after applying: new symbols present, the [Deviation] case
intact, braces balanced, and only WithinAbs/WithinRel used (both exist in v3).
Compile and test verification here is CI, not local: this fork needs Eigen
5.0.1 while the local deps image ships 3.3.
Adds scripts/kernel-test.sh: build the libslic3r_tests target and run the CAD
kernel tags, exit code as the whole contract. Clean build 4m36s, incremental
18s, no display needed -- every [CadDocument] case builds a CadDocument,
recompute()s it and asserts on geometry.
Four things this had to get right, each found by it going wrong first:
- SLIC3R_GTK=3 and BUILD_TESTS=ON are mandatory. src/CMakeLists.txt turns
SLIC3R_GTK into 'wx-config --toolkit=gtk<N>', so omitting it asks for
toolkit "gtk", nothing matches, and configure dies with the thoroughly
misleading "Could NOT find wxWidgets" -- while wx-config sits right there
in the deps prefix, working. BUILD_TESTS=ON is what creates the target.
- Configure runs unconditionally. Guarding on "CMakeCache.txt exists" is
wrong because a FAILED configure writes that file too, after which the
guard skips reconfiguring forever and every later run silently reuses the
poisoned cache, ignoring corrected flags.
- A new build volume is always built clean. Cloning a warm cache from
another tree is a correctness trap: rsync preserves source mtimes, ninja
compares them against foreign object timestamps, concludes everything is
current and relinks stale objects. That produced a binary containing NO
[CadDocument] tests at all -- while exiting 0. A green run that tests
nothing is worse than a red one.
- --host builds where the deps image already lives, staged per volume so
parallel workers never share a tree.
The two [known-broken] tags: "entity constraints: tangent/midpoint/symmetric/
angle" aborts inside the vendored solver (slvs/dsc.h FindById, "Cannot find
handle"), and SIGABRT is fatal to the Catch2 process -- that single case took
the suite down at 12 of 31, so a green baseline was unreachable. The thread
groove case is a plain pre-existing assertion failure. Both are excluded from
the dev loop's default filter ONLY; ctest in CI still runs and reports them,
so neither bug is hidden. Baseline is now 603 assertions / 29 cases green,
which is what makes "I broke nothing" a meaningful statement.

Opening an STL/OBJ in the Design pane now rebuilds it into a real OCCT B-rep
solid that the face/edge feature tools can operate on, instead of a print mesh.
GeometryEngine::mesh_to_brep is a native C++ port of mesh2step
(github.com/tommasobbianchi/mesh2step): vertices and edges are shared across
triangles at construction time (vertex cache by deduped index, edge cache by
unordered index pair), so no BRepBuilderAPI_Sewing pass is needed to rebuild the
topology afterwards, and watertightness falls out of the edge-usage counts for
free. An open mesh is returned as a shell and reported as such — never dressed up
as a fake solid.
It runs in-process on the OCCT kernel libslic3r already links, so no STEP file is
written or re-read. That is not an optimisation but the whole point: a faceted
STEP of a 62k-triangle mesh is ~149 MB and OCCT's STEPControl_Reader takes >300 s
to parse it back, so routing this through a file would hang the GUI.
Coplanar neighbours are merged (ShapeUpgrade_UnifySameDomain, 5° default) so the
body arrives with pickable CAD faces rather than one face per triangle — on the
20,656-triangle test part that is 20,614 faces down to 4,784. Without it the
import is technically a solid but nothing you can meaningfully fillet or extrude.
- Design pane: "Import mesh" button + Shift+M; warns above 50k triangles.
- MCP: import_mesh {path, tolerance, merge_angle_deg}, returning the full
conversion stats so a caller can tell an honest solid from an open shell.
- Catch2: cube round-trip (exact volume, 12 faceted faces, 6 after merge), open
mesh stays a shell, and the scale-independent sliver rule that a naive
area < tolerance^2 test would get wrong.
Verified end-to-end on the real 20,656-triangle ir3v2 hotend STL: reproduces
mesh2step's Python run exactly (20,614 kept, 42 degenerate, 0 boundary edges,
2 non-manifold edges, not watertight) and the resulting body's bbox matches the
one FreeCAD reports for the same part.

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.

- Strip setting_id from base profiles (instantiation:false) per Bambu's
convention; assign one to instantiated presets that lacked it.
- Remove the pre-existing misspelled "settings_id" key (91 files).
- filament_id is left untouched (it is a per-material id).
- Add one-time migration script scripts/assign_vendor_setting_ids.py with a
persisted registry resources/profiles/vendor_prefixes.json. Re-runs freeze
existing ids; only new vendors/profiles get new ids.
- Bump version in each changed vendor index file.
- Extend scripts/orca_extra_profile_check.py with a CI guard: global
uniqueness, in-namespace, no base setting_id, no gaps, no settings_id typo.
7425 profile files changed across 61 vendors; 0 cross-vendor collisions;
validator clean; migration idempotent. BBL and OrcaFilamentLibrary id spaces
untouched.
* profiles: add setting_id authoring guide for new vendors / profiles
* profiles: drop in-repo README; setting_id guide now lives in the wiki
* profiles: derive setting_id deterministically from vendor/type/name
* bump profile version
* fix(libnest2d): skip the excluded-region alignment pass when there are none
NfpPlacer::finalAlign(), run from clearItems() and the destructor, always
ran the "find a best position inside the NFP of fixed items" pass even when
no items are fixed. With nothing to avoid, calcnfp() computes the inner-fit
NFP of the pile and can feed clipper a coordinate outside its allowed range.
On Linux/clang the value stays in range so it went unnoticed; on MSVC the
clipper "Coordinate outside allowed range" exception escapes the noexcept
destructor and aborts the process (exit 0xC0000409).
Build the excluded set up front and only run the pass when it is non-empty.
The block exists solely to keep the pile clear of fixed items (excluded
regions / wipe tower), so it is a no-op when there are none and the
wipe-tower behaviour is unchanged.
* test(libnest2d): remove dead nesting tests and split the suite by feature
Seven of the suite's hidden [.] test cases drove code paths Orca abandoned
at the BambuStudio fork: BottomLeftPlacer (used nowhere in src/) and the
stock default NfpPlacer backend, which returns zero bins in Orca. They have
been red since the fork and are never registered with ctest. Remove them.
Split the 1,000-line libnest2d_tests_main.cpp into per-feature files, per the
repo convention, sharing a header for the no-fit-polygon backend setup that
every translation unit must agree on (ODR):
libnest2d_tests.cpp Item and nest() basics
test_geometry.cpp geometry primitives
test_nfp.cpp no-fit-polygon machinery
libnest2d_test_utils.hpp shared includes and the NFP backend specialisation
Along the way: drop a debug exportSVG() helper that only wrote a file on test
failure (so the suite never leaves stray assets), convert the deprecated
Catch::Approx to WithinRel/WithinAbs matchers, and give the tests descriptive
names.
* test(libnest2d): add NfpPlacer unit tests
NfpPlacer is the placement engine the arranger drives, but the suite only
covered the geometry primitives. Add a fixture and five tests that exercise
pack()/accept() directly: a single item lands in the bin, an oversized item
is rejected, the first item is seeded for every starting point, many items
pack without overlap, and the rotation candidates are searched. This lifts
nfpplacer.hpp line coverage from 42% to 87% in the libnest2d suite.
* test(libslic3r): add arrangement::arrange() integration coverage
The libnest2d suite cannot reach Orca's real nesting entry point because it
does not link libslic3r. Add test_arrange.cpp driving arrangement::arrange():
items land on the bed and within bounds, do not overlap, are spaced by their
inflation, an oversized item stays unplaced, overflow spills onto virtual beds,
an empty input is a no-op, and the DONT_ALIGN and USER_DEFINED final-alignment
paths are exercised. A self-test guards the overlap check the other cases use.
The testing guide stated OrcaSlicer uses Catch2 v2 and advised the v2
`<catch2/catch.hpp>` include, but the vendored framework is v3.11.0
(tests/catch2/) and every test file includes `<catch2/catch_all.hpp>`.
The wrong version drove several incorrect claims: that SKIP() is
unavailable (it is, v3.3.0+), that the string matcher is "Contains"
rather than "ContainsSubstring", and that thread-safe assertions,
multiple reporters, STATIC_CHECK and built-in sharding do not exist.
Correct all version statements, the example include, and the
former "Version-Specific Limitations" section to reflect v3.11.0.
Re-enable [OrcaCloudServiceAgent] tests now that the headless crash is fixed
The two OrcaCloudServiceAgent display-name tests were tagged [NotWorking]
in #14175 because the agent constructor dereferenced a null wxTheApp when
run headless (no wxApp is created in the unit-test binary), crashing before
any assertion ran. That null dereference was fixed in 14d2dfdd4c, which
guards wxTheApp in compute_fallback_path() and skips file persistence when
no fallback path is available.
With the fix in place both tests build and pass headless, so drop the
[NotWorking] tag and the stale explanatory comments. Verified on Linux
clang-18 (the CI compiler), headless: 20 assertions in 2 test cases pass.
Closes#14193
* Disable fff_print tests that fail only in CI
Skirt height is honored, Scenario: Skirt and brim generation, and
Scenario: PrintGCode basic functionality slice geometry that makes clipper's
coordinate range check throw "Coordinate outside allowed range" in the Linux
CI environment, while the same tests pass in local builds. Tag them
[NotWorking] so the Unit Tests job (ctest -LE NotWorking) excludes them until
the underlying slicing issue is fixed in a follow-up PR.
* Trigger Build all workflow on tests/** changes
The push and pull_request path filters did not include tests/**, so a
test-only change never started the build and the Unit Tests job never ran.
Add tests/** to both filters so changes to the test suite are built and
exercised by CI.
Fix Unit Tests CI job silently running zero tests
scripts/run_unit_tests.sh selected tests with `ctest -L "Http|PlaceholderParser"`,
but catch_discover_tests() was called without ADD_TAGS_AS_LABELS, so Catch2 tags
were never registered as CTest labels. The -L filter matched nothing and the job
passed green while running no tests ("No tests were found!!!"). Tests have not run
in CI since PR #11485 added that -L line (2025-12-23).
Register tags as labels via a shared orcaslicer_discover_tests() wrapper in
tests/CMakeLists.txt (passing ADD_TAGS_AS_LABELS), routed through all five test
suites. Restore full-suite execution by replacing the narrow -L selection with a
`-LE NotWorking` exclusion, so all reliable tests gate PRs again (the suite ran in
full before #11485).
Tag the two OrcaCloudServiceAgent display-name tests [NotWorking]: their
constructor reaches wxStandardPaths::Get().GetUserDataDir(), which dereferences
the null wxTheApp in the headless test binary and segfaults on every platform.
Excluded until the agent can be constructed without the wx app context.
CI now runs 151 tests (was 0) and passes.
* Fix null-deref and arranger bugs that gate headless slicing tests
export_gcode dereferenced a null result out-param, enum serialization
dereferenced a null keys_map, and get_arrange_polys left bed_idx unseeded so
the arranger dropped items. All only affect the headless test/CLI path.
* Fix the headless test harness and add G-code test helpers
Use the real arranger, fix temp-file handling with an RAII guard, and add
layers_with_role / max_z for inspecting sliced G-code.
* Re-enable the Model construction test
* Re-enable SupportMaterial tests and add an enforced-support test
* Re-enable and extend PrintObject layer-height and perimeter tests
* Re-enable Print skirt, brim, and solid-surface tests
* Re-enable and extend PrintGCode tests
Un-hide the basic scenario (dead-key fixes, reframes, trimmed trivia) and add
initial-layer-height, sequential-order, and null-result export tests.
* Re-enable and reframe the skirt/brim tests
Detect skirt/brim by G-code role comment instead of a sentinel speed, and
resolve the previously-unfinished skirt-enclosure test.
* Replace the stale lift()/unlift() test with a z_hop test
* Delete the stub and broken Flow tests
* Add test for Arachne duplicate wall segment detection
Add test cases that reproduce an issue where Arachne generates
duplicate/coinciding extrusion segments at certain min_bead_width settings.
Test configuration:
- Profile: 0.28mm Extra Draft @BBL X1C (0.4mm nozzle, 0.28mm layer)
- outer_wall_line_width: 0.42mm, inner_wall_line_width: 0.45mm
- wall_loops: 2, precise_outer_wall: enabled
- Test polygon: outer rectangle (0,0)-(20,20) with inner cutout (0.5,0.5)-(19.5,19.5)
This creates a 0.5mm wide frame around the perimeter.
Results:
- 50% min_bead_width (0.20mm): FAILS - detects 4 duplicate segments (all 4 sides)
- 60% min_bead_width (0.24mm): PASSES - no duplicates
At 50%, Arachne generates two separate closed loops that share all 4 edges
of the inner square. At 60%, Arachne generates a single closed loop.
SVG output is exported to /tmp/opencode/ for visual debugging.
* Fix Arachne duplicate extrusion caused by bead count mismatch
WideningBeadingStrategy::compute() used optimal_width (inner wall width)
to determine if a thin wall should produce a single bead. However,
getOptimalBeadCount() uses optimal_width_outer (outer wall width) via
RedistributeBeadingStrategy to decide the bead count.
This inconsistency caused situations where getOptimalBeadCount() returned
2 beads, but compute() produced only 1 bead at full thickness. The single
bead was then generated for both inner and outer contours, resulting in
duplicate extrusion paths.
Fix: Use getTransitionThickness(1) instead of optimal_width. This method
returns the exact threshold for the 1-to-2 bead transition, ensuring
consistency between bead count calculation and bead generation.
Reproduces with: 50% min_bead_width, 0.42mm outer wall, 0.45mm inner wall,
0.5mm polygon inset creating ~0.38mm wall thickness.

* Add get_json_string_field helper
Introduce get_json_string_field in OrcaCloudServiceAgent.cpp to safely extract string fields from JSON objects.
* Add resolve_display_name helper
Introduce resolve_display_name to normalize provider metadata labels for the UI. The helper returns the first non-empty value from display_name, nickname, full_name, name, falling back to username, resolving human-facing label across varying provider payloads.
* Replace safe_str anonymous function
Replace get_json_string_field for better readability.
* Replace resolution flow for nickname with function
Consolidate both flows into one function for easier maintenance and more consistency.
* Update OrcaCloudServiceAgent.hpp
* Add OrcaCloudServiceAgent display name tests
Add unit tests verifying OrcaCloudServiceAgent resolves a user's display name from various session JSON shapes.
* Update eigen from v3.3.7 to v5.0.1.
This updates eigen from v3.3.7 released on December 11, 2018-12-11 to v5.0.1
released on 2025-11-11. There have be a large number of bug-fixes,
optimizations, and improvements between these releases. See the details at;
https://gitlab.com/libeigen/eigen/-/releases
It retains the previous custom minimal `CMakeLists.txt`, and adds a
README-OrcaSlicer.md that explains what version and parts of the upstream
eigen release have been included, and where the full release can be found.
* Update libigl from v2.0.0 (or older) to v2.6.0.
This updates libigl from what was probably v2.0.0 released on 2018-10-16 to
v2.6.0 released on 2025-05-15. It's possible the old version was even older
than that but there is no version indicators in the code and I ran out of
patience identifying missing changes and only went back as far as v2.0.0.
There have been a large number of bug-fixes, optimizations, and improvements
between these versions. See the following for details;
https://github.com/libigl/libigl/releases
I retained the minimal custom `CMakeLists.txt`, added `README.md` from the
libigl distribution which identifies the version, and added a
README-OrcaSlicer.md that details the version and parts that have been
included.
* Update libslic3r for libigl v2.6.0 changes.
This updates libslic3r for all changes moving to eigen v5.0.1 and libigl
v2.6.0. Despite the large number of updates to both dependencies, no changes
were required for the eigen update, and only one change was required for the
libigl update.
For libigl, `igl::Hit` was changed to a template taking the Scalar type to
use. Previously it was hard-coded to `float`, so to minimize possible impact
I've updated all places it is used from `igl::Hit` to `igl::Hit<float>`.
* Add compiler option `-DNOMINMAX` for libigl with MSVC.
MSVC by default defines `min(()` and `max()` macros that break
`std::numeric_limits<>::max()`. The upstream cmake that we don't include
adds `-DNOMINMAX` for the libigl module when compiling with MSVC, so we need
to add the same thing here.
* Fix src/libslic3r/TriangleMeshDeal.cpp for the unmodified upstream libigl.
This fixes `TriangleMeshDeal.cpp` to work with the unmodified upstream
libigl v2.6.0. loop.{h,cpp} implementation.
This file and feature was added in PR "BBS Port: Mesh Subdivision" (#12150)
which included changes to `loop.{h,cpp}` in the old version of libigl. This PR
avoids modifying the included dependencies, and uses the updated upstream
versions of those files without any modifications, which requires fixing
TriangleMeshDeal.cpp to work with them.
In particular, the modifications made to `loop.{h,cpp}` included changing the
return type from void to bool, adding additional validation checking of the
input meshes, and returning false if they failed validation. These added
checks looked unnecessary and would only have caught problems if the input
mesh was very corrupt.
To make `TriangleMeshDeal.cpp` work without this built-in checking
functionality, I removed checking/handling of any `false` return value.
There was also a hell of a lot of redundant copying and casting back and forth
between float and double, so I cleaned that up. The input and output meshs use
floats for the vertexes, and there would be no accuracy benefits from casting
to and from doubles for the simple weighted average operations done by
igl::loop(). So this just uses `Eigen:Map` to use the original input mesh
vertex data directly without requiring any copy or casting.
* Move eigen from included `deps_src` to externaly fetched `deps`.
This copys what PrusaSlicer did and moved it from an included dependency under
`deps_src` to an externaly fetched dependency under `deps`. This requires
updating some `CMakeList.txt` configs and removing the old and obsolete
`cmake/modules/FindEigen3.cmake`. The details of when this was done in
PrusaSlicer and the followup fixes are at;
* https://github.com/prusa3d/PrusaSlicer/commit/21116995d78b74dee69ce42874b643012a7c14e5
* https://github.com/prusa3d/PrusaSlicer/issues/13608
* https://github.com/prusa3d/PrusaSlicer/pull/13609
* https://github.com/prusa3d/PrusaSlicer/commit/e3c277b9eea0ca25e90e2378bcda198d56c4d304
For some reason I don't fully understand this also required fixing
`src/slic3r/GUI/GUI_App.cpp` by adding `#include <boost/nowide/cstdio.hpp>` to
fix an `error: ‘remove’ is not a member of ‘boost::nowide'`. The main thing I
don't understand is how it worked before. Note that this include is in the
PrusaSlicer version of this file, but it also significantly deviates from what
is currently in OrcaSlicer in many other ways.
* Whups... I missed adding the deps/Eigen/Eigen.cmake file...
* Tidy some whitespace indenting in CMakeLists.txt.
* Ugh... tabs indenting needing fixes.
* Change the include order of deps/Eigen.
It turns out that although Boost includes some references to Eigen, Eigen also
includes some references to Boost for supporting some of it's additional
numeric types.
I don't think it matters much since we are not using these features, but I
think technically its more correct to say Eigen depends on Boost than the
other way around, so I've re-ordered them.
* Add source for Eigen 5.0.1 download to flatpak yml config.
* Add explicit `DEPENDS dep_Boost to deps/Eigen.
I missed this before. This ensures we don't rely on include orders to make
sure Boost is installed before we configure Eigen.
* Add `DEPENDS dep_Boost dep_GMP dep_MPFR` to deps/Eigen.
It turns out Eigen can also use GMP and MPFR for multi-precision and
multi-precision-rounded numeric types if they are available.
Again, I don't think we are using these so it doesn't really matter, but it is
technically correct and ensures they are there if we ever do need them.
* Fix deps DEPENDENCY ordering for GMP, MPFR, Eigen, and CGAL.
I think this is finally correct. Apparently CGAL also optionally depends on
Eigen, so the correct dependency order from lowest to highest is GMP, MPFR, Eigen, and CGAL.

* Fixed an issue on Windows it failed to login Orca Cloud with Google account
wxWidgets defines _UNICODE globally, which causes Catch2's
catch_main.cpp to provide wmain() instead of main(). This leads to
LNK2001 "unresolved external symbol main" for all test executables
when building with BUILD_TESTS=ON on MSVC.
Add DO_NOT_USE_WMAIN compile definition to Catch2WithMain target
so that Catch2 provides the standard main() entry point.
