Sorry to disagree. If the "instructional material" was worth a darn these questions wouldn't be so common. It is hard to even know where to get help with AutoCad's convoluted websites and multiple sites/forums etc.   It takes forever to figure anything out because it is a challenge to fine useful tutorials for beginners that don't assume you know how to do things, or where to find commands. Most of the help is on the order of:

"... click the draw line tool to draw a line..."  or something stupid like that. If I knew were the draw line tool was I wouldn't need to be told to click it.  

Just my $0.02 worth.
