This has been easy with OpenSCAD for a long time. I have made lots of cool, complex models this way. I built a repo of the prompts I use to show the llm how to do this and it includes many of the models I've created this way...
Same. Working with an LLM and OpenSCAD has been totally painless.
What is the inference overhead on this
OpenSCAD has almost zero crossover with B-rep modelling ('true' CAD, what this apparently is), though.
