What is your workflow for llm integration to openscad?
For very simple geometries it works great, but it very quickly becomes apparent that there’s a bit of a disconnect between “LLM views image” and “LLM emits scad that looks like that image” when it comes to anything non-trivial.
Still gives me a starting point I can mess with, which is great since I have zero CAD training or experience.

Once you have learnt a bit then the only FOSS options that are worth a damn are a) SolveSpace which is quite good and light, has a slightly quirky UI (but not in a bad way) but unfortunately has some critical missing features at the moment - notably bevels/chamfers. Although I did see someone made a sloppy PR to add them so we'll see where that goes.
Or b) FreeCAD which is actually good now and fairly close to SOLIDWORKS (at least for the basic stuff you're likely to use) and has a reasonably good UX. Some rough edges still but overall it's very usable. Good enough that I reach for it instead of pirating SOLIDWORKS these days.
The basic workflow is pretty simple:
1. Make some planes, referenced from existing geometry. 2. Make sketches on the planes. 3. Extrude/revolve them (either adding or subtracting from the existing geometry). 4. Repeat until you have the right shape. 5. Add a load of chamfers to make it pretty.
For LLM-assisted bespoke model generation it's still fine if you specify a process to follow, and can "speak the language" (knowing 1-5).
This is no different than purevibe vs LLM-assistance, IMHO. What TFA refers to is a more end-to-end, no iterative process, with no single touchpoint script like OpenSCAD offers, so it's very much _not_ a collaboration and requires no knowledge of how CAD models are made.
But this thread is moreso about iterating on an OpenSCAD specification using LLMs.
I've one shotted a light saber hilt with threaded parts and it worked flawlessly.
