I do it with enthusiasm, if not grace. I hope you were helpful to your
visitor. I was searching for a reliable text to resolve this whole
thing. I must have it here somewhere, but it has escaped.
I use VectorWorks for drawing. I'm very pleased with it. It handles
3D and 2D with a certain friendly grace that is really quite pleasant.
My impression is that a lot of exhibit and stage set design people are
using it.
