You'll know how incapable it is when it doesn't seem to understand how servo motors work in the Demo Project.

Re: Text-to-CAD
#12I built https://github.com/brookstalley/cordyceps to do CAD work using claude code.
It's not perfect by any stretch, but it is surprisingly strong. It was able to create and debug some pretty complicated geometry by iterating with screenshots, adjusting view angle and zoom and rendering mode, updating parametric geometry generation, and working to fairly complex goals.

#13I have been using Claude to generate OpenSCAD for 3D printing. It works decently when the jobs are simple and can be easily described, but the description part really makes it clear how little vocabulary the ordinary person has to compose a good picture of any real item that isn't just a basic shape. It seems that the trick, like most things with getting LLMs to do something complicated and have it work well, is to be an expert in the field already.
Re: Text-to-CAD
#14I just posted this somewhere else -- but overall big fan of these text to cad rigs as projects. Obligatory mention of https://zoo.dev/ who went to extreme lengths on this. I will say I explored this reasonably deeply and came away with the conclusion that even though we have OpenSCAD and all these examples, LLMs are still very weak at spatial reasoning compared to diffusion models. You can do all sorts of tricks like…
> LLMs are still very weak at spatial reasoning compared to diffusion models Don't know what diffusion model can do, but 100% agree with the "LLMS are very weak at spatial reasoning" comment. I build a rather complex blueprint-image-to-3D-brep-model a couple of months back using codex ... ugh the damn thing has really no idea where things are in space, something a 3 year old figures out instinctively. It did end up s…
This sounds like a cool project, I would love to hear more about it. I am trying to solve a similar problem myself.
Re: Text-to-CAD
#15I've been using an OpenSCAD container with various local models. Dumping the render.png straight to the model, allowing it to modify the code and try again. Made some interesting things, but the main purpose was to fix things I've already made and have some weird single issue that cascades to a broken model if I touch it. OpenSCAD is the first step, FreeCAD and similar(now starting to see more CAD LLM work) are still a WIP. Since january we've solved 4 solid issues I've left on backburner. I use the docker container version with some Custom wrap/bridge work for the render dumps.

The problem is that the jump to OpenSCAD to a BRep based modeler is not quite a jump. It’s more like scaling a 10,000 foot sheer cliff in terms of the level of difficulty difference. You’ll be on that WIP for quite a long time

#17The demo should be a pelican on a bicycle of course.

#18Without benchmarks and/or a whole suite of non-cherrypicked examples, this means nothing because you can trivially make an AI generate anything from text.

Working on benchmarks at the moment! Always open to feedback / PRs.
