(Since I’m not aware of the details…) Is this similar to using NURBS as the representation in Blender?
As in what makes this more CAD-ey?
You can make Blender work as a CAD-ish tool with practice and self-discipline and lots of keyboard shortcuts. But e.g. Fusion360 or even SketchUp is what a CAD-oriented workflow feels like. There is a big difference.
Haven't tried this yet, but I expect it to retain enough of the CAD-oriented approach that the workflow still feels quite different from Blender.
Not 100% correct. There are a number of add-ons that do this. I even think someone managed to hook-up the solvespace engine in a blender add-on
There are also a whole slew of add-ons that can make Blender more CAD-friendly.
However, you are correct, this is not the primary intent of Blender.
Nurbs are good for some shapes and bad for others. In addition to manufacturing, nurbs are great for hard surface / scifi assets for video games and movies.
Plasticity is for artists. It is more in the tradition of MoI3d than say solidworks. It has a very powerful geometry kernel and the user interface is meant to be familiar to blender users and modern looking.
It’s still very beta and changing every day
