Great start! I have a feeling this is going to cascade (no pun intended) in ways we haven't quite wrapped our heads around. What is the underlying technology here? Is this an LLM driven workflow or Image generation driven workflow? I can imagine a way to do something similar either way given a dataset geared a particular direction. Speaking of... anyone have a lead on a CAD-esque dataset? I have been trying to use lo…

Do people really want train a LLM on CAD models treating them as text? I would be more interested in trying to work from the conceptual model behind the exchange file format.

What about dimensions? It's a good starting point, but which software can use this to alter the dimensions precisely? This should have been called Text-to-3D.

If it's spitting out STEP files, just about any of the major CAD packages will do it.

There's probably mileage in just generating python that calls the FreeCAD API.

It says they're generating a STEP file, and that's just a text format. Fine-tuned LLM would be my guess.

Earlier quoted context omitted.

It’s trivial to take a 2D image DALLE3 or midjourney generate and vectorize it (illustrator etc.)

That kind of vectorization is a royal pain to edit.

inkscape is pretty go at everything except simplification.

DXFs are also text files.

The only LLM-as-a-service I use is phind for the sole reason that it allows me to use it without "signing up" first. If the sign up is a necessary barrier for your needs is for you to decide, but I just wanted to let you know that I was excited to try your product for my wood working and 3d printing needs until the required signup. Just some anecdata that even a little friction can be a hindrance in people using your…

If I may ask, why are you so against signing up for these tools?

When ever I see CAD mentioned on hackernews it's always 3D and never the more ubiquitous (in the construction industry) 2D documentation CAD. I wonder if this would be able to generate 2D vector files.

I've noticed the same problem, no LLM to manufacturing/construction CAD yet as far as I can tell?

It would be nice to feed the LLM a set of dimensions, constraints, desired features, etc and have a few different versions generated. Quickly explore the problem space of designing house for a piece of land, or for 3d printing.

that's not really suitable for the manufacturing/building route
