Neat, but I don't really see the utility. The time consuming part of CAD drawing comes from figuring out the correct dimensions of each feature, spacing, sizing, tolerances, etc., and constraining the drawing in a way so that it's easy to tweak later on- which this doesn't do at all. Maybe you could draw a 2d sketch of what you want then generate it, but you'd still have to do the hard part.

How can I convert openSCAD models to true STEP files? As in no meshes. I Literally have wanted that for years.
You need to use https://github.com/smurfix/buildscad which can convert OpenSCAD to Build123d, then you can export a STEP file. It has a few limitations, but for simple OpenSCAD files it can generate an equivalent representation in OpenCASCADE.

I’ve been using cadquery and build123 with Claude code and I find it incredibly painful. What is your workflow for llm integration to openscad?
I just ask it for what I’m looking for (doing very simple “spare part” level at home 3d printing, nothing fancy or elaborate) and it gives me a starting point. Then I sometimes just edit the scad code by hand, and some times I ask the AI to revise, sometimes a mix (many iterations). For very simple geometries it works great, but it very quickly becomes apparent that there’s a bit of a disconnect between “LLM views im…
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.

If down the line this model could create 3D model from 2D images that would be very neat way to pay less for war gaming models

Tbh that sounds harder than just learning CAD, which is really not that difficult if you use a proper parametric editor - I would recommend SOLIDWORKS first. It's got the easiest UX so is ideal for learning. They actually have a vaguely reasonably priced subscription now, but IMO it's still way too much for occasional hobby use so I'd recommend just pirating it (which is easy).

Missing IKEA screws.
This is over a year old now, why post now? There have been other advancements in this area.
