Reflected Parallel Projections (the old question)

An option for this dialog box. There is already “Rotation;” it would be really useful if there were also a “Flip” or “Mirror” option. I’ll send you two samples by private message, since I can’t republish them; one is from Frank Ching’s, Visual Dictionary of Architecture and the other is from the mighty IES handbook. People who can’t see those can view some samples at this Georgia State class notes site, as long as it is up.
