I don't know if there even is documentation for any of that. I'd recommend watching Stacker's tutorial videos. Stacker teaches you all these crazy tricks but he explains things really well. His lessons cover multiple level rooms and dozens of good navigation techniques.
So where can I find an official user manual for Base Construction? You know, something that explains the UI, explains the whole power/control scheme, how to make multiple-level rooms, adding/deleting rooms and the implications, etc.
For instance, I find that rotating the "scene" with the RBUTTON is barely adequate because the pivot for rotation is stuck on one corner of the base. Surely there is a way to adjust the rotation pivot point. And surely there are ways to move rooms around without having to empty them out, sell them, rebuy/place them, move items back into them, etc.
Where is all this documented?
