I drew an addition for a client and in the process somewhere I lost the floor of the living room in the existing house. It will no longer let me open the room. It still has a vaulted ceiling and walls and such, but if I take a 3d camera view, it does not have a floor. Like I said before, I have tried repeatedly to open the room as an object to no avail. I have checked to be sure that all of my walls defining the room are touching each other. The room still has its foundation. I can open in it the foundation level. It still has a roof. I just cant find anything wrong to make the floor disappear other than it no longer being a room as if there were a break in a wall....Any help would be greatly appreciated.
