I’ve still been waiting to see case studies of Sub-D parts winding up in actual production workflows. Ex a part that gets built, imported into an engineering tool like ProE/SW, and shipped off to tooling for something standard like injection molding.
I agree that Sub-D modeling is a much faster workflow for concept. But surfacing workflows can still be very fast for a large amount of forms, even if the learning curve is steeper. And the question brought up earlier is “Once it’s no longer a concept, then what?” - the last thing you want to do is enable someone to design a form that can’t actually have draft applied, split lines controlled, thickness added, etc.
Not saying it can’t be done, but I’m out of the game and haven’t seen those types of workflows showcased past 3D printing.
