Text-to-CAD

Plugin★ 24.8K GitHub stars

A plugin that has a coding agent design 3D parts through conversation: the agent writes the part as a Python (build123d) script, a local engine turns it into a STEP, STL, 3MF or GLB file, and the model is shown in the agent app or the browser. It also runs manufacturability checks for sheet metal, CNC, injection molding and 3D printing, and handles dimensioned technical drawing PDFs, G-code, off-the-shelf part search (screws, bearings, motors) and file checks before a SendCutSend order. Includes 12 skills and a local MCP server.

For: Small businesses developing products, 3D printing and fabrication shops, and engineers using Claude Code, Codex, Cursor or Gemini. Someone who doesn't know CAD software can describe a part but needs to check the output with measurements.
