Actually, AutoCad is not that hard to use. It is probably more expensive than most will want to pay for a beginning program.
I have never had AutoCad14 training, but am using it on this project. Just like any other program, be it spreadsheet or word processor, just jump in and go with the simple, then learn the more difficult. If you know someone in the business close to you, they will be glad to answer your questions and show you how to use the program.
There are several programs at Wal-Mart and other office supply stores in the $50 range that would probably serve for your learning experience, in addition to the ones mentioned here in this thread. I have considered one of those for home use, but haven't had time to use it even if I bought it. Maybe for Christmas??
