Edit: I realize I was imprecise, I specifically was referring to 3D CAD for mechanical parts of the type you would generally produce a print for i.e. with controlled geometry and dimensioning. A) That's a surface modeler. B) Parametric CAD doesn't have boilerplate in the same way as software. In a part, you have a feature tree, and a lot of thought goes into constructing the feature tree in a way that both allows for reconfiguration and also somewhat resembles the manufacturing process. Every step depends on the previous step in a way that is necessarily impossible to isolate. If you make a step without being aware of the end state of the tree, you will probably have to redo a bunch of the tree if the part is complex. Also that's not what mechanical engineers spend most of their time doing. Plenty of MEs can code and use an LLM btw, nothing stopping them from optimizing their work processes if they saw fit, yet you don't really see the shoehorning of AI into the space yet.
