Q: What is SolidCraft?

SolidCraft is a code AI tool listed on Use AI Tools. SolidCraft is an open-source parametric 3D CAD application written in pure Rust, available on desktop, in the browser and through an MCP server that lets AI agents model for you. It sketches with a real constraint solver, builds a feature timeline of extrude, revolve, sweep and loft operations, and exports STEP, IGES, STL, OBJ and URDF. Agents get tools for execute, inspect_design, measure, set_parameter and screenshot. Dual MIT or Apache-2.0 licensed, and self-described as early but usable for simple parts.

🎯 Real-World Use Cases

Agent-Driven Modelling

Let Claude Code build and rebuild parts through the built-in MCP server

Parametric Editing

Change one dimension and watch the model regenerate from the timeline

Scripted Export

Run the headless CLI to measure, render PNG and export STEP or STL in batches

⚖️ Honest Review

✅ Pros

+One codebase runs on Windows, macOS, Linux and the browser via WebGPU or WebGL2
+Imports STEP, IGES, 3MF, STL, OBJ, glTF, FreeCAD and Rhino files
+Exposed UI handles and a JSON-lines channel let agents drive the desktop app directly

⚠️ Cons

−Explicitly early, with only simple parts described as reliably usable
−Downloads are unsigned, so Windows SmartScreen and macOS Gatekeeper need overrides
