> They obviously showed a lot of meticulously mated actual 3D components but those were all prepared in a CAD program.

Do you have any reference for that?

If so, they wouldn't need gravity sketch at all. The most popular CAD programs already have VR support:

Rhino -> https://www.mindeskvr.com/

Maya -> https://www.marui-plugin.com

3dsMax -> 3dsMax Interactive (Autodesk)

Blender -> https://github.com/MARUI-PlugIn/BlenderXR

Those are 3D programs, but not CAD. For CAD you'd expect Solidworks, Catia and PRO-E.

Modeling programs make art, CAD is for engineering. They’re very different.

Yes, but I want to point out on odd edge-cases that's not always true.

For example, when designing something for 3dprinting, I sometimes prefer modeling programs over CAD programs because I have control over, for example, however a sphere is made up (the style of polygons, tesselation, that sort of thing). When you're slicing for a 3d printer, you can get odd bugs if your stl is made in a non-optimal way.

I've used most of those tools, they are all pretty terrible to use. You can't very easily take a rendering engine designed for massive geometric modelling and just plug VR into it without major performance sacrifices. I always got a headache after using them.
