So what is innovative in Plasticity, other than offering Parasolid and XNurbs at a cheap price?

Is there anything original that works well and isn't just copied from another app?

The only thing I'm seeing for that so far is being friendly to Blender users.

I don't think there is any other CAD program that has structured its UI to be familiar to Blender users, so that is a legit innovation but limited to that user group.

The focus on that probably sacrifices quite a lot of usability to a lot of other types of users especially beginners though.

Also a heavy Blender user would probably prefer to stay entirely within Blender rather than go to an external app so Plasticity seems very vulnerable to SDF modeling plugins running inside Blender.
