I dabbled in Autocad for a couple of semesters, to see what it was about. Good stuff, but not as applicable to machining.
I think I would do almost anything to find an auto cad program, just to play around with.
I took drafting in high school, but didn't enter the work force until my kids had left home. I'd just like to play with something like that, and find out how much I know, and how much I'm capable of.
(FYI, when I was in high school, I was the only female in the drafting class. I was an A student.)
