I dont really know about that… A real Nurbs implementation requires a lot of “complex” math- and is for sure no simple task…
But for Blender as Part of a Industrial Design workflow, alongside a
Nurbs Modeller (Rhino, Alias, Solidworks…etc) some smoother connectivity would be great (and realistic to achieve)
So First, getting Nurbs data inside Blender for rendering animation, simulations etc with some proper Importers
for the Standard formats (Iges,Step) would be key.
(there has been some amazing start on the rhino 3d format- I hope it continues!
Import Rhinoceros 3D files into Blender )
But with your suggestion, it would be possible to do also big Parts of the Design work inside Blender and to get data OUT of Blender and beeing able to continue detailing the Design in one ofe the Nurbs Modeller!
This would be SOOO BIG in my personal workflow!
Having both, would make Blender 2.8 not “just” beeing widely adopted in Animation-Studios, but also in
IndustrialDesign Studios as well!
