I've been getting into 3D printing recently and while the flagship Anthropic models can regurgitate community wisdom about the hobby they can't do spatial reasoning. They'll tell me that objects will fit on my print bed when they won't and vice-versa. They get confused about materials and nozzles. It takes several iterations to get them to do basic objects (in my case a slotted tray) in OpenSCAD. Useful, certainly, but very far from autonomous for end-to-end manufacturing workflows.
