Never did any fortran drawing. Saw the schools computer, and poo pooed it. Was already doing very nice orthographic explosions with pen and ink. In fact, the drawings I did look better than the crap they generate today with Solid Works.
Kinda sad, I found a Mac program that took Solid Works data files and output illustrations that were as good as my own. Nobody except for me could figure out how to use it so it was abandoned. It really was not difficult.
I have a font we used that I made from actual Leroy Lettering so CADD drawings would match pen and ink drawings closer.
Look familiar?
