As of now I am focussing on just that lofted room above garage, and the ceiling heights, etc of the other floors are irrelevant at this point. suppose im happy with how that room is layed out, and simply want to add this shed dormer, do I have to go thru all of these default settings and resets, etc? I still seem to be stumbling here with this auto roof as it keeps altering everything to the extreme...and seem to struggle with your much appreciated instruction. I thought I was better with this software once upon a time
