Yep, all those. Still teach a bit of hand drafting. Especially lettering. Kids hand writing these days sucks.Just one!
You've got to have an Engineer's scale - and an Architect's scale - and then there are the metric scales!!
My engineering drafting classes were also very close to the last ones that didn't involve computer aided drafting. 1st year engineering final exams were all slide rules only, but 2nd year final exams allowed TI SR-51A or HP-35 calculators. Radical!!

I'm probably one of the last people on earth still running an HP 41 everyday.
