Because a lot of people are saying "CAD is only useful if you know how to use it." One word:

Tinkercad. https://www.tinkercad.com/

I teach children how to use it. It takes them about 15 minutes to pick it up. Are you going to design a car with it? No. But if you look at all the Text2Cad programs so far, they won't either. If you need to design something for 3d printing, Tinkercad, in terms of ease of use/simplicity, is hard to beat. And it's free to use.

I've played with other Text2Cad projects, and I've yet to be able to get anything out of them other than the most simple shapes, which frankly, what's the point if it can't make an object that's useful or meets my requirements? It takes way too much time having to write out paragraphs to even get the most basic of brackets built. I remember on the Zoo app, it very much likes typical CAD language which means you're going to need to be able to speak "CAD" anyways when trying to create a successful part (think: constraints in typical CAD)

What these LLM programs really need to focus on (imo) is writing Openscad (and similar "programmable CAD") code, which is going to at least give the user a better starting place, as well as the ability to edit their parts. I think one of the biggest constraints for this is the lack of millions of lines of code and documentation unlike most popular programming languages for the LLM.

I think the research is neat, but for now, it seems like a solution in search of a problem.

I started years ago with Tinkercad. Eventually I needed more and moved to Fusion 360. It's a natural progression. Tinkercad was a great place to start. Better than Text2CAD (sorry to the creators).
