Has there been any interest in leveraging LLM's for 3d modelling? Sort of an AI assistant with CAD software, to help beginners get going and also more rapidly design simple objects.
- iancmceachern 2y agoYeah, tons, there are already products like this in use
- lucasoshiro 2y agoCan you name them?
- iancmceachern 2y agoSeveral from Bambu labs to start

- oofbaroomf 2y agoYes, there has been. Unfortunately, there are a few core issues blocking this from becoming a big thing: 1. The majority of 3D modeling is not done parametrically, meaning there is not a lot of data. The little data there is is generally in OpenSCAD, which isn't very powerful or extensible for useful CAD. 2. Generally, when you want to do CAD, you need to come up with a way to define everything precisely. Like I want this hole 2 millimeters from the bottom, and this exact edge next to the hole to be beveled, etc. Saying all that to an LLM is slower than just making the whole. That said, these still can be useful for beginners, and there are things like Adam AI that are starting to catch on for simple stuff.
- ai-christianson 2y agoThere are AI models that can generate 3D models, e.g. Hunyuan3D. Not quite CAD models, but maybe this could eventually be adapted to that use case. Then there's the possibility of an agent automating an actual CAD program. This has already been done with game dev, e.g. Unity MCP.
- oofbaroomf 1y agoThings like Hunyuan 3D are nice for game assets and the like, but they aren't able to really do CAD well. That would be like using Stable Diffusion to code.
