I created a simple shape that represents the frustum of a projector. I have to change this (zoom angle and projection distance) to place the projector to a specific place in a room to fill the designed screen. I can do this in sketchup, but I am transitioning to Archicad. How can I add these parameters to modify the mesh/morph? I am really a beginner here, so go easy please
I have attached my first try.
