Re: Teaching LLMs how to solid model
#4Really cool, I'd love to try something like this for quick and simple enclosures. Right now I have some prototype electronics hot glued to a piece of plywood. It would be awesome to give a GenCAD workflow the existing part STLs (if they exist) and have it roughly arrange everything and then create the 3D model for a case.
Maybe there could be a mating/assembly eval in the future that would work towards that?

#5I've done this, and printed actual models AIs generated. In my experience Grok does the best job with this - it one shots even the more elaborate designs (with thinking). Gemini often screws up, but it sometimes can (get this!) figure things out if you show it what the errors are, as a screenshot. This in particular gives me hope that some kind of RL loop can be built around this. OpenAI models screw up and can't fix the errors (common symptom: generate slightly different model with the same exact flaws). DeepSeek is about at the same level at OpenSCAD as OpenAI. I have not tried Claude.

#6Wow! As someone that's written openscad scripts manually I can get real excited about this.

You've got to be a bit more specific, those words can all refer to many models.

#8Makes you wonder if there is a place in the pipeline for generating G-code (motion commands that run CNC mills, 3d printers etc.)
Being just a domestic 3d printer enthousiast I have no idea what the real world issues are in manufacting with CNC mills; i'd personally enjoy an AI telling me which of the 1000 possible combinations of line width, infill %, temperatures, speeds, wall generation params etc. to use for a given print.

#9I tried this a few months back with claude 3.5 writing cadquery code in cline, with render photos for feedback. I got it to model a few simple things like terraforming mars city fairly nicely. However it still involved a fair bit of coaching. I wrote a simple script to automate the process more but it went off the rails too often.
I wonder if the models improved image understanding also lead to better spatial understanding.

There is some industry usage of AI in G-code generation. But it often requires at least some post processing. In general if you just want a few parts without hard tolerances it can be pretty good. But when you need to churn out thousands it's worth it to go in an manually optimize to squeeze out those precious machine hours.
