Remove the boilerplate and focus on the value adding parts is the philosophy that actually happens in software development ai usage, so it might be useful elsewhere as well.

> Given an image or a 3D mesh, SGS-1 can generate CAD B-Rep parts in STEP format. Unlike all other existing generative models, SGS-1 outputs are accurate and can be edited easily in traditional CAD software
This is a game changer, all the models before that output meshes were a toy at best. Super excited to see where they can take this.
I wander if the next step is for a step -> proprietary format (SolidWork, NX etc) model that can infer constraints.

I agree, even if it just does a decent job of creating sane STEP geometry out of 3D scan meshes that would be a huge win.

Depending on pricing, this could be a boon for 3D printing. The really hard part for hobbyists creating novel models has been the CAD. If they can price this appropriately I can see it selling really well.
As an engineer I just wanted to pipe in and say that this AI removes the part of design that isn’t actually the difficult part.
The difficult part is the manufacturing, also coming up with the plausible load paths and deciding on the geometry of the parts according to the actual loads.
