Free camera mode (tab) and basements
While you can use your q and e keys to rise up and down through all the floors in free camera mode (tab) it won't let you go below ground level to the basement, unless you have page-downed to actually display only the basement. As soon as you page-up to erect the walls above basement (for example if you have the floor above the basement removed to make a double-height atrium) the camera position relocates to terrain level and you cannot sink below it.
