Seems a fit for any sort of 3D CAD work. I'd like to pair it with unconed's MathBox (https://github.com/unconed/MathBox.js).
Cad work is much better done with a mouse, you want quick, precise movement that takes little physical effort.
(I have been doing autocad and now revit for 22 years)
Now blender, on the other hand, is ripe for experimentation.
