SolveCraft v0.1.0

on GitHub

SolveCraft is an open-source parametric 3D CAD application in pure Rust: sketch on a plane,
constrain and dimension the sketch, turn profiles into solids on a feature timeline, and change a
parameter to watch the timeline rebuild. This is the first public build, a pre-release: it is
early, and we'd like your bug reports.

What works

• Sketches with SolveCraft's own constraint solver: lines, rectangles, circles, arcs, polygons,
  slots, splines, text; constraints and parameter-driven dimensions; automatic profiles.
• Solid features on a parametric timeline that rebuilds incrementally: extrude, revolve, sweep,
  loft, fillet and chamfer, shell, draft, holes and threads, patterns, mirror, combine, split,
  primitives. Faces and edges are referenced by persistent names, so upstream edits don't
  scramble downstream features.
• Parameters with unit-aware expressions, and configurations.
• Components, joints, motion studies, sheet metal with flat patterns, and a plastic-enclosure
  subset (bosses, lips, snap fits).
• Files: .solvecraft designs; STEP (AP203/214/242) and IGES import and export; 3MF, STL and OBJ;
  DXF. Atomic saves, autosave and crash recovery.
• 76 of 76 reference parts built in Fusion rebuild in SolveCraft with the same volume, area and
  topology.

Built for AI agents

Everything the UI does is a command with JSON parameters, so an agent can do it too.
solvecraft-cli mcp is a Model Context Protocol server: headless, or bridged to the running app
(solvecraft --control 7878, then solvecraft-cli mcp --connect 127.0.0.1:7878) so you can
watch the agent model. In Claude Code: claude mcp add solvecraft -- solvecraft-cli mcp. The
attached video shows an agent building an enclosure through the UI and MCP.

Downloads

The binaries are not signed

• macOS: the first time, right-click (or Control-click) SolveCraft.app and choose Open,
  then Open again in the dialog. If macOS says the app is damaged, run
  xattr -dr com.apple.quarantine SolveCraft.app. Do the same for solvecraft-cli.
• Windows: SmartScreen may say "Windows protected your PC". Click More info, then
  Run anyway.

Known limitations

SolveCraft is early. Some fillet, chamfer and boolean configurations still fail (with an error,
never a crash); surfaces, drawings, CAM, mesh tools and simulation are out of scope for now; the
model is Z-up only, so STEP files from Y-up tools open lying on their backs. The full list is in
ROADMAP.md.
