I have been knocking my head on this issue for parts of a couple of days. The ceilings look good on the second floor, and work great. I keep getting the message that the ceilings cannot display on the first floor ceiling plans. Why? Everything appears to be set the same. Can anyone give me some pointers to look at to get this corrected. The second floor has nearly all "out of the box" walls. The first floor had custom walls made for existing wall types.
