winget install --id=bherbruck.SolidCraft -e SolidCraft is an open-source parametric 3D CAD application built in pure Rust. Sketch, constrain, extrude, and change a parameter to watch the timeline rebuild. It runs on desktop and web, and can be automated through MCP with solidcraft-cli.
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.
sudo snap install solidcraft (Snap Store).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.
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.
.sc designs (.solidcraft files from earlier releases still open).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.

More commands, the Windows cross-build and the browser build are in docs/building.md.
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.
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.
