I liked OpenSCAD, but I couldn’t figure out how to do anything very advanced… until the LLMs became good. Now the LLMs are great at guiding me on rather complex projects.

If I were going to do it again, I’d probably learn solidworks. They have some great discounts which make it accessible for home users.

Oooh haven’t tried OpenSCAD yet with LLMs! I wrote a lot of OpenSCAD a few years ago for my CNC router projects and “vibe coding” a solid object would be very cool.

IME they're really not great at OpenSCAD or POVRay but some of them can at least produce syntactically correct SDL these days.

I gave ChatGPT a PDF of an academic paper and asked it to create an OpenSCAD program which replicated the paper’s design - knocked it out. Did it have issues? of course.
