I took a couple of arcitectural drafting classes in high-school, back during the (tail end of the?) hand-drafting days.
I enjoyed it so much I considered studying arcitecture in college. But I decided that in The Real World (tm) I'd be unlikely to be able to design the kind of building I had so much fun designing (the most common comment I received from the teacher was "do you have any idea how expensive this would be to build?!?"), and I'd probably be stuck designing rectangles composed of rectangles. So I choose another path.
But I am nostalgic for the drafting tables with the built-in movable rulers and the vellum, the mechanical pencils and the eraser-powder-bags, the triangular-shaped scale-rulers and the compasses.
