"I know this is aimed at industrial designers here, but I'm in the same boat Robyn. I'm a just graduated Theatre Design/Production student and I had to learn how to use all of these. I had to learn how to draft by hand before being able to be taught how to use CAD.If it makes you feel better about this generation though, I actually had a lot of these items leftover from the semester I spent in the Architecture program my freshman year of college.
