A solidcraft-mechanisms agent skill with a worked example that a test replays through the MCP server (the actuator follows the hinge with the stated stroke and the drive stops at the rod's limit); the skills index and docs/mcp.md list it.
While Draft, Accessibility or Curvature Map analysis is on, a legend at the bottom left of the viewport says what each colour means and which values it stands for, with the theme's analysis colours and stripes. Labels translated in en/de/ja/ko/zh. Fixes#973.
Without a 3DxWare profile, Linux now uses the driver's object-mode mapping (physical Ry and Rz swapped and reversed), so a tilt rolls and a twist spins. Windows and macOS are unchanged; a profile still takes precedence. Fixes#1172.
The bridged MCP server starts when no app is listening, says so in its instructions and in each tool error, and connects on the first call after the app starts. A batch that could not be sent says the app is not running. docs/mcp.md describes it.
snapshot starts from --in (a design or STEP file) with the script on top, as run does, and refuses options it doesn't take; an unknown command id names the closest registered ids.
A control-channel method that reads the orbit camera, sets any of target/yaw/pitch/roll/distance, and fits listed occurrences (or everything) keeping the direction. Its reply passed back sets the same view again; a refused field changes nothing.
joint.drive answers moved, and a reason (with unconnected) when the joint can move nothing; motion.play answers moved and unmoved; joint.list answers floating chains. joint.drive values come back in joint.list's shape (deg/mm). quiet: true trims joint answers and motion.play poses. A single value keeps a joint's other values. Drive Joints shows the floating case (drive.unconnected, all locales).
component.list {compact: true} gives counts of bodies, features, sketches and construction planes instead of their names, lists occurrences without identity transforms and children as occurrence ids; bodies: true keeps body names. The default form is unchanged.
* Preferences ▸ Graphics ▸ Display quality: Coarse, Normal, Fine, Ultra (#1287)
A viewing preference that sets how finely the viewport tessellates curved faces and edges:
chord tolerance relative to each body's size (3e-3, 1e-3, 3e-4, 1e-4) and the most a facet may
turn (30, 20, 12, 7 degrees). Normal is the tolerance the viewport has always used.
Bodies keep a display plan per level, so switching is a re-plan the first time and instant
after; the reference mesh the model reads (picks, holes, measuring) and exports are unchanged.
Away from Normal the model scene builds edges, and faces on the CPU path, from the plan at that
level, so silhouettes and edges get finer with the faces and a highlight still lies on the
displayed triangles.
The preference is saved with the others, set over the control channel (`ui.prefs`
`display_quality`), labelled in en/de/ja/ko/zh. `solidcraft-cli bench-open --display LEVEL
[--edit NAME EXPR]` times the plans at a level and after a parameter edit.

A regression test: an inside flange on a 100 x 60 plate turned by every whole degree from 0 to 89 builds and keeps the analytic volume. At 62 degrees the trimmed corner used to land on a border of the sew's vertex grid and the flange failed to close.
A fillet or chamfer on a cylindrical boss's bottom arc now builds with a closed display mesh: the seam-extension containment ray counts a shared curved-boundary endpoint once. Merging the split faces of a three-edge arc corner rebuilds the face on the original input face's full surface instead of a piece's restricted patch, and runs under the kernel's panic guard. Fixes#1262 and #1263.

The empty design shown at launch, New on a design that is still empty, file.new and the blank design left when the last tab closes all take the Units of new designs preference. Opened files and the sample part keep their own units. Fixes#1205.

Section Analysis clipped the origin and construction planes and axes along with the model. They now draw from their own unclipped lists, with the same depth and blending; bodies, edges, sketches and highlights are clipped as before. Fixes#1229.

A symmetric solid extrude of 10 mm is now 10 mm thick, 5 mm each side of the sketch plane, and switching from One Side to Symmetric keeps the thickness entered. Under format 21 the extent records its convention; designs saved without it keep the per-side reading, so their geometry and parameters don't change. Fixes#1236.

A round or chamfer whose edge chain runs on across a curved seam (the end circle of a lofted tube whose axis bends) is now built: the section solve keeps its contact on the seam through a plane taken afresh at the seam's nearest point at each step. Straight seams are unchanged. Robustness seed 41 is re-recorded: its second fillet, refused before, now builds. Fixes#1213.
Co-authored-by: gvocale <[email protected]>
A fillet or chamfer that consumes both seams of a side, leaving its old boundary and the fitted contact on the same curve, now returns TooLarge ("the blend would consume a neighbouring face") instead of a zero-area face that doesn't mesh. Genuine two-edge faces are kept. Fixes#1113.

A modelled thread as other CAD systems write it to STEP has cylinder faces trimmed by helices
that turn several times around the shaft, and cylinder faces bounded by two circles with no
seam edge. The display planner refused any face whose boundary winds around its surface, so
the whole body fell back to the reference mesher, which drew those faces with triangles across
the solid.
The planner now cuts such a face along a parameter line into one period: every loop and its
copies a period apart are clipped to the strip, and the parts of the cut line inside the face
join the pieces into closed loops, with the seam nodes made once for both sides. The cut face
is meshed by Delaunay with sag refinement, and the sag check runs once more after shaping.
Bodies with a face trimmed by more than one turn take their reference mesh (picking, measuring,
the CPU viewport) from the plan too.
Tests: an ISO M10x1.5 and M12x1.75 thread built from helices, as made and after a STEP round
trip: the display mesh stays within the tolerance of its surfaces and the thread's volume, and
has no degenerate, sliver or flipped triangles.

* Action matrix regressions of #1255: knuckle rounds, thin holes, a 45° flange hole, an axis after an edit
- Curve blends: past the end of a curved edge the run of sections along the end
tangent wrapped round the ring of centres; it is shortened while it still
crosses the end face (the hinge knuckle's cap rounds at 0.728 mm).
- Boolean retry guard: each body's volume is measured finer than its smallest
radius, and a volume out of bounds is measured again ten times finer before
it refuses (a 0.133 mm drill measured -30272 mm³; a plastic part's coarse
mesh was off by more than the slack).
- Sheet metal: a drill cap's certificate allows the evaluation noise its fitted
tilt shows (a hole square to a 45° flange).
- Construction geometry on a named face uses the face found by name, not a
second pick at its nearest point (an axis through a corner round after a
parameter moved it).

* Retry guard: measure the target, tool and result at one tolerance
Measured at different tolerances, the chords' error on the faces they share
didn't cancel: a blind hole in a long D-profile bar measured 20 mm³ more than
the bar.

The three walks over a feature (expressions, references, geometry) are generated from FeatureKind by #[derive(Walk)] in a new proc-macro crate, solidcraft-derive, from #[walk(...)] attributes written next to each field. The hand-written walks in params.rs, feature_refs.rs and feature_geometry.rs are gone; Ruled Surface and Extend have their attributes, and the three golden walk records are unchanged.

A corner whose two curves end on separate points held together by a Coincident constraint (a line drawn to where an arc starts) is welded into one shared point before Fillet or a Chamfer rounds or cuts it, so it no longer reports that the corner must join two lines. Only a partner point held by nothing but that constraint is welded. Fixes#1208.

* Title bar: inactive tabs without outlines, File menu, Help on the right
Inactive tabs go back to the plain bar colour (the Home tab's readable
hover stays). The separate Home button and theme toggle are gone: Home is
a tab and the theme is in Preferences. The folder icon becomes a File text
menu, Save moves into it (Ctrl+S unchanged), and Help sits on the right
next to Report a bug. Tabs start right after File, Undo and Redo.

An opt-in Touchpad navigation preset: Shift + pointer motion pans, Alt/Option + motion orbits, vertical scroll zooms, all without a mouse button. Existing presets are unchanged; view.navigate gains continuous motion for the control channel and scenarios.
Extend works on any surface: natural (continuing the face's own surface), tangent (G1 run-off) or curvature (G2 run-off), by a distance, up to a plane or face, or back to the surface's bounds, with neighbouring edges lengthened to meet. Untrim and Extend share face parameter-loop helpers. The new SurfaceExtend fields are noted under format 21. Closes#760.
A design note for SolidCraft in the browser: tiered storage, a SharedWorker job broker, GPU dispatch and in-browser agent control through the same engine commands, with the generic pieces in craft-libs. Linked from the MCP and web getting-started docs.
A loft section with a hole is refused with a clear message instead of being lofted as if filled, in both section-to-section and section-to-point lofts. Fixes#1184.
The labelled Report a bug button takes its translated label's width, so longer translations no longer run over the Preferences gear; narrow bars still fall back to the compact icon. Fixes#1145.
Browser rows that are names someone gave (bodies, sketches, components, joints, views...) show as typed instead of being translated as UI labels; default names like Sketch1 are still translated. Fixes#1228.
Ruled Surface: strips off an edge chain in normal, tangent, angle or direction mode, exact planes/cylinders/cones where possible, mitred or round corners, stitched into one surface body. SurfaceRuled is noted under format 21. Closes#762.
* Smart Extrude: direction from the picked side, Cut into a body stays a Cut (#1257)
- A sketch profile (or a thin extrude's curve) extrudes toward the side it was
picked from: from the bottom view it goes down. Body faces still go outward.
- The automatic operation is latched per side of the profile: a drag that starts
into a body is a Cut and stays one past the far side; a Join does not become a
Cut when it reaches another body. Passing through zero decides afresh for the
new side.
- An explicit operation, Direction or Reverse ends the automatic choices.
- auto_operation also looks just past the profile, so a long cut through a body
reads as a Cut from the start (the engine's operation: "auto" too).

#1164 joins a body that sits flush on a rounded rim into it. In seed 13 the
rectangular pattern's second box (x 5..7.5) sits flush on the half-ring's top
face with a 27 mm2 contact patch. It used to stay a separate shell (one body,
three shells); now it joins the ring (area -54 mm2, twice the patch). The
fillet edge and hole position the generator picks next come from the new
geometry, so the end state differs: 3 bodies, 2647.95 mm3 (was 4, 2300.91).
Every step stays a sound solid, and no other seed moves.

* Action matrix: nightly shards cut by measured cost, heavy designs in slices, and a determinism check
The full matrix ran as four fixed quarters of the corpus and two of them hit the 60-minute
job limit. Now action_matrix_shard runs shard k of n (ACTION_MATRIX_SHARD=k/n), planned from
tests/action_matrix/costs.json: designs that take more than five minutes are split into slices,
and the pieces go largest first to the least loaded shard. The nightly runs 12 shards and uploads
each one's outcomes and timings; cargo xtask action-matrix --from DIR --bless records them in the
baseline and costs.json without running the matrix again. action_matrix_determinism runs a sample
twice and lists any action whose outcome changed.

* Action matrix: costs measured on runners, 10 shards, determinism on the lighter designs
Co-Authored-By: Claude Opus 5.5 <[email protected]>
* Action matrix: baseline and costs from a full run on main, 16 shards, timeouts listed
The baseline is regenerated from the 10 shards' results of a full run on 01b1b705
(cargo xtask action-matrix --from DIR --bless): 8 new designs, 302 actions that pass now,
names that changed, and 40 actions that passed before and fail now, each listed in #1255
(22 fillets refused since #949, 4 hinge blends since #1101, 9 on the loft cut, 5 single).
costs.json now holds every design's measured time, and the nightly runs 16 shards of about
17 minutes. An action that passes in the baseline and times out is listed but not judged,
and stays passing when blessed: two runs of the same build differed only on 10 actions that
took 50-84 s against the 90 s limit.

* Action matrix: slice heavy designs by a hash of each action's name
Slicing by index gave some slices only fillets on oracle 41 (28 slices, a multiple of the
actions per edge), three times the planned time; two shards ran past their limit.

The preview builds only the tool; the boolean runs once on OK, off the window thread, with a Computing label while it takes a while. Follow-up to #1020.
Lands the Render workspace (R3), bounded preview-image jobs with cancellation and atomic PNG export (R4a), and opaque PBR looks as one change.
- Render workspace: an overlay-free product preview on the installed GPU device. Returning to Design restores its camera. render.scene and render.settings.apply are added.
- Image jobs: render.preflight/start/status/cancel/export run bounded CPU preview jobs. Export captures the job, overwrite choice and document, and checks the caller's file scope before writing.
- Opaque PBR: looks can carry metal fraction, roughness and dielectric IOR. The product viewport and preview PNG use them; geometry and mass are unchanged. The v1 catalog export refuses PBR rather than dropping it.
- Render setups and PBR looks are saved under design format 21. Labels are in en/de/ja/ko/zh/ru.
Supersedes #706 and #800. Refs #620, #673, #756, #1004.

Adds a French catalog as a partial locale (missing strings fall back to English, like Russian), registered in the language list, with tests and attribution.
A design carries metadata (format 21): project, part number, revision, author, organization, description and license, plus other tools' data under reverse-DNS keys, kept as written. Edited in the Design Properties window (Document Settings), set by document.metadata.set, reported by inspect_design, and written into STEP, IGES and 3MF where the format has a place for them. Translated, with tests.
The AMD FirePro D300/D500/D700 Metal driver hangs on the tessellation compute shader and macOS resets the GPU, freezing the desktop. Bodies are built on the CPU on that device, and SOLIDCRAFT_CPU_TESS=1 forces the CPU path on any GPU. The check is a tested predicate, and the troubleshooting guide documents the variable.
