Thanks so much! this should be very helpful. I'm still a little confused about the whole ceiling thing but this should help me figure it out. I have a slightly different problem. While working on a build I saw that some rooms had ceilings (eh, I guess they all did, but anyway..) and the option to remove the ceiling if you clicked on the room. I have a room where I want to remove the ceiling and I can't get the option to come up. The ceiling is there...I see it when I angle up, I just can't figure out how to remove it. Any suggestions? maybe I'm having the non-room, room issue?
@gamergirlgeekfreak; Sometimes when I find that I have a "non-room/room and it's creating a problem I find it easier to use the room tool to build the exact same shape of the room with the room tools (not with the wall tool) somewhere else on the lot. Then I move it and place it on the non-room/room. If it was decorated it usually doesn't interfere with anything unless there is some other kind of conflict. Anyway, it just creates an "ACTUAL ROOM" and you don't have to change anything else in the build.
