I have no real info or talent in C A D programs...... BUT I do know I and a friend of mine both wasted $100 on a PUNCH software program "Professional HOME DESIGN Platinum " version 8.... I presume that 1 thru 7 are equally as bad..... We both wasted HOURS trying to get ANYTHING to come out.... YOU must have to have a computer degree I guess... The best I got was an octipussey looking thing that was supposed to be a deck with stairs ??? I believe to get an E A S Y to use program you must spend some real money so dig a bit deep and make sure you know what your buying....
