Overview

The text-to-cad plugin gives your agent local workflows for generating 3D models as STEP, GLB, STL or 3MF files. It also does design for manufacturing checks, generates engineering drawings, and connects to popular 3D printing, sheet metal and CNC fabrication services.

It is supported by all popular agents that support plugins or the skills framework, including Claude Code, Codex, Cursor, Gemini and Grok.

Install

Ask your agent (recommended)

Send this message to your agent and it will install text-to-cad for you.
