I've been learning to use Autodesk Revit as of late.  While studying, I found this great set of Youtube tutorials on every aspect of the program.  It's very easy to understand (even for me).The quality is a bit grainy, but if you have the program open, you can follow along on your own screenhttp://www.youtube.com/user/ddufon#play/uploads/24/Gma2PRegpjU
