I've started using claude code and codex for CAD design. I realized that the agents weren't able to see what they were building, so I made agentcad, a tool to help agents "see" and iterate over their work.

You can see a demo here: https://github.com/jdilla1277/agentcad - it's free / open source.

Some notes:

• it's code to cad, not text to mesh
• it's build for agents to do their own work and then hand off to you; you can see an example single-stage 2:1 spur-gear reducer I made in the gif

Would love to have y'all try it out and then give me feedback!

Free, open source, runs locally.

It lets your favorite coding agent run build123d scripts and "see" the output.

One thing I noticed when using coding agents to write build123d models was that the code would run but the result would have obvious visual errors... so I built agentcad.

Think of it as CAD software for your favorite coding agent. Agentcad allows Claude / Codex / Cursor to "see" and verify what it's building before handing it back to you.

Just tell your coding agent what you want it to build and step back and let it work; it will hand you back STEP/STL/GLB files when it's done, along side a viewer that lets you see what it's made / provide feedback.

It's free, open source, and runs locally.

Here's an example of one of my projects with it: building the 1903 Wright Flyer from the architectural drawings: https://agentcad.dev/see-it-in-action
