Another free 2D AutoCAD look-alike is ProgeCAD 2009 Smart!. It's got a learning curve, but I didn't find it too onerous. I bought an AutoCAD LT "how to use" book, started at the beginning, did the exercises and examples, and after about 3 chapters suddenly "got" the AutoCAD way of viewing the world. With that fundamental understanding, it suddenly became a lot easier. There is a considerable amount of stuff I don't know about the program, but I know enough to get by and do what I want to do.
