My only saving grace there was that my dad was a Land Surveyor and made heavy use of AutoCAD. We had the full digitizer tablet and access to a color plotter.

I didn't care so much for the 2D stuff, but over time I taught myself a lot about modeling stuff in 3D. I blew people away in drama club one year when I showed up with a rendering of the auditorium, stage, and lighting locations for one of the plays.
