Can't select room, floor/ceiling disappear
I am having trouble with a model I am working on. I have my exterior walls defined, and am placing interior walls. One of the rooms is giving me trouble. When I close off a portion of the room, it no longer allows me to select the room, and in 3D it removes the floor covering and the ceiling. When I delete the interior wall, it all goes back to normal. It isn't that complex of a room, though there are some curved walls. I have tried connecting my interior walls along straight walls, but am still running into the same issue. I am new to CA, so this may be an easy fix. Any help is appreciated.
