text-to-cad: give Claude Code or Codex the ability to design real 3D parts (17k stars)
I'm not a CAD person. Every time I needed a simple bracket for a 3D print, I lost an evening fighting a modeling app I barely knew.
text-to-cad is a plugin that lets your coding agent do the CAD part for you. You describe the part, and the agent generates a real 3D model as STEP, GLB, STL or 3MF files.
And it goes further than just making shapes. It runs design for manufacturing checks, generates engineering drawings, and connects to 3D printing, sheet metal and CNC fabrication services.
It works with the agents you probably already use: Claude Code, Codex, Cursor, Gemini and Grok. Install is literally telling your agent to install it from the repo, or two commands if you prefer doing it yourself. Everything runs locally through uv.
The part I liked most is the viewer. In Claude Desktop, models show up as cards in the chat that you can orbit and point at. Claude can see what you selected. In a terminal, you get a link that opens the model in your browser.
Is it perfect? No. Complex mechanical assemblies still need someone who knows what they're doing to check the result. And the first start downloads a runtime, so you need a network connection. But for quick functional parts, this saves a LOT of time.
