Thanks Eric. I hope I can figure out how to replicate what you did but I'm already stuck. The concept of Snapping the Roof isn't clicking for me. Are you completing this step in the 3D or Plan view? When you say 'left' you mean the left side of the building when you are facing it, correct?
Also, please give a little more instruction on 'Drag the top wall left and continue counter clockwise to form the smaller garage'. I'm not understanding how to drag a wall counter clockwise.
Thanks you for assistance and most importantly your patience with this newbie.
Jason
