> A complete V8 internal combustion engine Yeah, no, that's a lie. This isn't a CAD model. It's a fantasy 3d model that looks like it's straight out of Gearhead Garage (1999). Any time I see these 'AI CAD' solutions it's always toys, toys, toys. Show me something functional that you've actually manufactured (shitty 3D prints don't count). Or at least show me something that can actually be assembled and isn't just a b…

> shitty 3D prints don't count Why not? The 3D print market is pretty large and tools to generate some designs that can then be tweaked are pretty useful in that context. I don't think that type of AI CAD tool would replace professional CAD work, that's something that requires way too much context and human judgement. But being able to prototype something to be 3D printed via an AI thing is one of the few places wher…

Yes I intentionally called this AI TinkerCAD

"I need an engine mount for 1999 toyota land cruiser j90 for the 1kz-te engine with a manual gearbox. Can you generate me a cad to send to a company in China to 3d print it?" "Done — I've created a heavy-duty, fully parametric engine mount bracket that fits a typical four-bolt block pattern and a single-stud chassis isolator with an alignment pin, much like what the 1KZ-TE requires." I dont think it's even close :( P…

There's already a lack of information online for simple things like torque specs. I can't imagine that a skilled professional could design the engine mounts even with if they had all of the relevant context online.

As far as I know, the way that these reproduction hardware companies operate is that they have physical cars that they can design around.

I have a 1993 Subaru WRX and I needed to replace the coolant header tank because mine had a bunch of leaks. I ended buying one from a specialty fab shop in the UK and I had to make a few measurements for them because there was varying bolt spacing for GC8 Impreza models.

I asked it to create 3d model of "AMF-O97L45-DB". It pulled datasheet and generated 3D model. Left is reality, right is what was generated: https://imgur.com/a/oNaz51q - wrong pitch - wrong pins position - missing pins

curious how this compares to on baseline: https://adam.new/

let me know!

did you try to iterate? copypasting your brief message here to the prompt would probably fix something.

yes i agree, this would probably fix it

I find all current LLMs to have pretty poor spatial awareness. It is becoming better, but still very poor. How are you dealing with that? Got any special tricks, any advice?

My favorite spatial reasoning benchmark: https://minebench.ai/

no tricks, I'd definitely be curious to know how much screenshots help

I have a general question regarding 3d design using LLMs. My understanding is that all current applications have been trying to deal with 3d design/CAD as text/code. LLMs are clearly good at those but do you see this as the long term approch for 3d designs? do you see world models eventually evolving to produce 3d spaces or point clouds or CAD designs instead of doing video? is this approch explored? Congrats on the launch!

I strongly believe that by scaling up LLMs we will get there. I write about this here in more detail: https://adam.new/blog/bitter-lesson-ai-cad
