3D Free Form Region Arithmatic

Prof. Mc Clure suggested that we use Wolfram Cloud’s native 3D renderer since the Observable implementation might be difficult if we deal with raw polygons.

I just modified his code on the Observable but added a Free Form grammar which is live on Wolfram Cloud accepting parsing requests.

I did choose a bit challenging topic of region arithmatic e.g. Difference to exhibit the Free Form interface and how easy it is to use.
