> I see a lot of comments here to the effect "but it's easier to just do it in CAD in the first place" -- those are experts speaking.

This is what I think, and yet I am the longest time away from being an expert.

It's easier because CAD tools unlock CAD thinking and empower your brain to actually do design, as well as helping you see problems you didn't anticipate.

This whole area -- LLM to CAD -- is one of the most misguided applications for generative AI (beyond "generative design" as it was understood in the pre-LLM/pre-GAN era, where it was usually used for FEM/topology optimisation)

There are already enormous libraries of freely available basic CAD models for real-world objects; any beginner would be much better off simply learning how to merge them. And any tool aimed at beginners would be better off assisting that process (TinkerCad does, for example)

And if a beginner has a truly novel object to make, an LLM is not going to have the training set data to make it. Nor is the beginner likely to have the CAD knowledge (words, expressions) to describe it.

For this to be of use to a beginner you do have to imagine quite a niche kind of beginner: one who is expert in descriptive language and advanced geometry. Those people would be better off learning some sort of CAD environment; indeed they are the niche that is least likely to be driven insane by the limitations of OpenSCAD.
