I have been using a program called DraftSight to view *.dwg files that people send me. It's a free 2D program that is a less functional version of a commercial program. I haven't tried using it to create drawings (I use a true 3D program for that) but it looks like it would be easy enough to learn to use. Seems like there is enough support out there for it to help get somebody started.
I use a program on my ithingies called Machinist Journeyman. It around $10 but I've gotten my money out of it many times over. Lots of built-in calculators for bolt circles, trig, RPM, feedrates, machining time, plus tables of dimensions for UN screw threads, tap drills, drill diameters, etc. Very handy. Don't know if it comes in any other platform besides the Apple version.
