Sizing A Doorway or Window

[lanatolman]

I have a wall that is 29' 5" and I need to place a doorway of 65" and a sliding door of 104". I put them into the wall put they are not placed in the right place along the wall. When try to move them the wall next to the doorway or window moves not just the doorway or the window. I have tried everything I know how to do to make my wall from the corner 6" wall --- doorway 65"---wall 60" --sliding door 104" --wall 119"

Also when I go to camera view my system freezes. I have a ATI GL 3100 Video Display
