Have your AI agent draft CAD drawings in a free, open-source app
CADCraft is a free, open-source 2D/3D drafting program that your coding agent can drive through text commands instead of a chat window.
It's a program for drafting plans, parts and drawings (2D/3D CAD) with open-source code, built like AutoCAD but free and controllable by an AI agent.
When it helps
Useful when you need a precise drawing — a room floor plan or a dimensioned part — without buying AutoCAD; it won't fully replace AutoCAD yet since it's still in early development.
Pros
- Completely free, open-source code (MIT or Apache-2.0)
- Runs on an ordinary laptop, no strong graphics card needed
- Reads text commands, so your own agent can draft for you
- Opens and saves DXF/DWG files, same as AutoCAD
Cons
- Not yet at AutoCAD's feature level — still early development
- Reads DWG through reverse-engineered code, not Autodesk's own — some old files may fail
How to set it up — step by step
- 1Install Rust with the one-line installer, or download a ready binary from the Releases page.
- 2Build CADCraft from https://github.com/storytold/cadcraft, or grab the binary from Releases instead.
- 3Start CADCraft's MCP server so your agent can control the app through text commands.
- 4Send the agent the text from the block below.
- 5Check the result: open the drawing it created (a room plan or a dimensioned part) and view the image.
Text for your agent
Copy this and send it to your agent — Claude Code, Codex, any of them:
Build CADCraft from https://github.com/storytold/cadcraft (or grab a ready binary from Releases), start its MCP server, and ask my agent to draft a simple drawing from my text description — a room plan or a dimensioned part — then show me what it made.
A regular laptop — no GPU needed, just Rust (a one-command install) or a ready binary from the releases.
