* Face names: one name on two bodies is no split face (#10699) A hole placed on the top of one of two bodies an extrude made, or on a piece of a split body, warned "face `F2:top` was split; using the piece nearest the picked point": the face name is on both bodies, and any name found more than once counted as split. A name on several bodies, one face on each, now finds the face the point lies on without the note; pieces on one body, or a point on none of them, still say split. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com> * Hole: look for a face name shared by two bodies on the body the point is on (#10699) The lookup over every body counts a name on several bodies as split on purpose (a copy's face is not a piece of the source's, see `the_same_face_on_a_copy_is_not_a_piece_of_the_named_bodys_face`), so the first change, which made it unique there, is undone. A hole whose face name is found split while its point lies on one of those faces now looks again on that body alone: one face of the name there is the face, whole; pieces on that body still say split.

SolidCraft
An open-source parametric 3D CAD application built in pure Rust.
Sketch, constrain, and build solids with a parametric feature timeline. Change a dimension
and watch your model rebuild. Run it on your desktop, in your browser, or let AI agents
model through the built-in MCP server.

A Raspberry Pi 4 case from an empty design: a sketch dimensioned with the board's parameters, extrude, fillet, shell, the rim rounded in one pick, an M2.5 standoff patterned on the 58 × 49 mm hole rectangle, port cut-outs, vent slots, "Pi 4" engraved in DejaVu Sans Bold and a PETG material defined in the design, with its mass in Properties, then height 24 → 32 mm in Parameters and it all rebuilds. 6× playback with the idle pauses cut. Full video, recorded with the demo script.
Download
- Windows: the installer.
- macOS: the disk image (Apple silicon and Intel).
- Linux: the AppImage, or
sudo snap install solidcraft(Snap Store). - Web: try it in your browser, no install.
ARM64 and 32-bit builds, portable zip, .deb, .rpm, Flatpak and the other packages are on the downloads page. The macOS app is signed with a Developer ID and notarized by Apple. The Windows downloads aren't signed yet: choose More info, then Run anyway in SmartScreen. On SolidCraft 0.11 to 0.14, download once by hand; see updating.
What works
Early but usable for simple parts: 75 of 76 public reference parts match their analytic or FreeCAD-computed volume, area, centre of mass and bounding box (oracle); the other is a tracked bug.
- Sketches and constraints: lines, arcs, splines, text and more, solved by our own constraint solver, with parameter-driven dimensions.
- Features: extrude, revolve, sweep, loft, fillet, chamfer, shell, draft, holes, threads, patterns, mirror, split and combine on an editable parametric timeline.
- Parameters and configurations with unit-aware expressions.
- Assemblies with joints, motion studies, contact sets, interference and mass properties.
- Sheet metal with flanges, hems, fold/unfold and flat patterns, and plastic enclosure features.
- Files: STEP, IGES, 3MF, STL, OBJ and glTF in and out where supported, URDF export,
.scdesigns (.solidcraftfiles from earlier releases still open). - Desktop app, browser app, headless CLI and MCP server, all running the same commands.
The full list is in docs/capabilities.md and docs/features.md; status and plans are in ROADMAP.md. See also what people built, 3D mouse support and the architecture.
Build from source
cargo run --release -p solidcraft -- --sample # desktop app with a sample part
cargo run --release -p solidcraft-cli -- commands # the command registry
cargo run --release -p solidcraft-cli -- run examples/bracket.json --out bracket.step
cargo xtask ci # fmt, clippy, tests, icons, assets, layers, wasm
More commands, the Windows cross-build and the browser build are in docs/building.md.
AI agents (MCP)
solidcraft-cli mcp is a Model Context Protocol server. Headless it
runs its own design session, or with --connect it drives the running app so you can watch.
Claude Code: claude mcp add solidcraft -- solidcraft-cli mcp. If a terminal doesn't find
solidcraft-cli (older Windows installers don't put it on PATH), give its full path (by default
"C:\\Program Files\\SolidCraft\\solidcraft-cli.exe"). Tools, access rules and an example session:
docs/mcp.md.
Scripts
A script is a JSON list of the same commands the UI runs, executed with solidcraft-cli run.
Format and example: docs/scripts.md. Pages can also be driven through the
browser command API.
