To be honest from the sample prompts they provide you would be lucky if any two pieces fits together.

What is the Architectual equivalent of a hand with twelve fingers and nonsense lettering

a McMansion

Probably the Winchester Mystery House: https://en.wikipedia.org/wiki/Winchester_Mystery_House

Disappointing to see Jessie Frazelle building closed source centralized tech. This approach mirrors "Open"AI sending all queries to central servers with no mention of any privacy measures. The admins surely get to see who is making sex toys, prop weapons, or medical parts and that data will be sold or leaked, as is tradition. This is a great idea though and I look forward to supporting whoever makes an open source al…

Oxide & Friends had some recent episodes about keeping the lights on when working on open source. IIRC titled something like "Corporate Open Source Anti-Patterns."

TLDR: FOSS devs still need to eat, so we'd better come up with a sustainable biz model, so we can keep working on FOSS.

My play is I sell my advice and experience, and find companies willing to pay me to write open source software to meet their needs.

I have built a security firm that only audits code/ architecture and writes open source code and it can generate enough income to support a few people in a way I feel good about.

I try to put people before profit and that is probably why I am not cut out to be a billionaire.

I'm really looking forward to the future of this area, especially parallel developments in image-to-CAD. It would be incredible to get an accurate model by taking a couple of photos and then inputting measurements. Sure, you can 3D-scan something, but that makes a messy point cloud when real world objects are mostly make out of primitives that could be far more exactly duplicated.

Same here, I've been doing chatGPT -> scad or blender scripts, but it ain't the same at all

Huh, I never thought of trying to use GPT for scad. Does that actually work?

Try refreshing.

Came back after dinner, and it was done. Trying some prompts: - "1/4 inch bolt, hex head" -- result is a cylinder with no bolt head. - "1/4 inch bolt" -- "The prompt must clearly describe a CAD model" - "1/4 inch threaded rod, 3 inches long" -- same - "0.25in threaded rod, 3 inches long" -- same - "Plate, 3in x 5in, with rounded corners." -- same - "Plate with rounded corners" -- blank result Now it's too overloaded…

Now it's working under Firefox.

Weird, though, I asked for "6 inch by 6 inch plate with four bolt holes for NEMA 42 motor frame, centered on plate".[1] That should get me four holes in a square pattern. It got me three holes.

It has no clue what the standard NEMA motor frame sizes are, because I asked for a nonexistent NEMA number and it accepted it. That's an LLM hallucinating, probably. It's not an acceptable feature in engineering.
