second floor roofs

[daydreamer]

wayne,

Because you have Auto Rebuild Roof unselected (Off) go into the Attic level and click on a wall, press and hold the Shift key while you select and click on the remaining walls. When all the walls have been selected press the Delete key. The Attic walls won't rebuild until you rebuild the 2nd floor.
