I think we are looking at a misunderstanding.
All I have been doing thus far is essentially puzzling paper copies of the studio sets together to make them as onscreen-accurate as possible.
This will serve as the basis for my friend Andy to turn my "dirty" drafts into clean 2D (!) CAD blueprints.
I can't do 3D, neither can my friend Andy. For the time being, I hope that one talented 3D artist will eventually turn my deck plans into 3D.
