Vibe coding a robot with GPT 5.5! This is a URDF of a 7dof robot arm with functional kinematics, a custom gui, and STEP parts/assembly, 100% generated in Codex (minus the gripper). A similar result would have taken me weeks stitching half a dozen tools together. Insane stuff.

first stable release for text-to-cad (0.1.0) - bambu labs + gcode skills (prompt to print) - 3x faster STEP builds, 5x faster viewer - plugins for codex, claude, gemini - tonnes of new viewer controls - contributor friendly repo (!!) about to cross 5000 stars, 20k downloads

step . parts is an open source directory of 12,000+ STEP parts for your next CAD project it's designed to be an agent-friendly, MIT licensed version of mcmaster that isn't behind a sign up / paywall the api has been used 10,000 times in ~2 weeks to download useful parts (a lot of them are me cadslopping) !!

Say hello to text-to-cad, an open source tool for generating 3D models in Codex! Prompt and edit complex 3D models. Export STEP, STL, GLB, DXF and URDF files. Built for CAD newbies. Link to github below. CAD is hard. As a software engineer getting back into robotics, I’ve been humbled by new tools like Onshape. Struggling to kick old habits, I started prompting Codex to generate 3D models and had some limited succes. After a few iterations I found a recipe that actually works: 1. Generate a python script for every STEP file. The agent can easily edit each part’s source without touching the raw STEP file. Use build123d > cadquery. 2. Reference specific faces and edges in prompts for precise edits. I built a basic local ui to inspect / cache STEP B-reps to make this easier. 3. Maintain markdown explaining important part features in plain English so the model can index on project context quickly. 4. Verify results with screenshots and geometry. Models don’t have great spatial awareness, but they can interpret images and verify constraints very well. For the best results I’ve been using GPT 5.4 xhigh / Opus 4.6+. Fair warning, this will burn through tokens, I recommend the Pro/Max plans if you’re planning on building anything serious. PRs welcome!

new text-to-cad release! - LOTS of robot demos (link below) - sendcutsend skill for DMF checks - sdf skill for sim - srdf skill with moveit2 support i want to give agents a complete set of skills to iterate towards mechanically sound hardware designs from loosely defined specs
