Tags: ai, cad, 3d-modeling, agent, mcp, plugin, manufacturing

Score: 7.5/10 (Innovation: 7, Technical: 8, Documentation: 8, Utility: 7)

text-to-cad is a plugin that gives AI agents the ability to generate 3D CAD models (STEP, GLB, STL, 3MF) from natural language, perform design-for-manufacturing checks, create engineering drawings, and connect to fabrication services like 3D printing and CNC. It integrates with popular agents (Claude, Codex, Cursor, Gemini, Grok) via the skills framework and MCP, leveraging Open CASCADE and build123d for robust CAD operations. The project is notable for its broad agent compatibility, local-first architecture, and comprehensive documentation.

Target audience: mechanical engineers, hardware designers, AI agent developers, makers
