If you are using Q's mods...use 0.0 , 0.0, 0.0 as the coordinates for all of the rooms in your layout file. If you import each room model into gmax or 3dsmax, they all have the same aurora base coord (0,0,0) and the room is built in relation to that.
That's what I did for one of his
Code:

filedependancy 520OND.max
