Multiple project base point or anything similar?

[LOESCH_PK]

Quick question: Is it possibleto have multiple project base points or anything equivalent within one Revit file? I have a situation where I have an exsisting building, and we're building a new one connected to it, so I would not want to seperate them into different files (well, not yet). But at the same time I would like to indicate a different 0 level for both of them. 

I'm quessing that my only options are either to seperate them into two files or move the base point up and down when I want to export something from them. Or is there any other option that I'm missing?

No such thing. But you can use this trick to show different levels with the same name: edit the copy of Level 0, right click and rename it to Level 0 and add an Unicode character to the name.  You now have two Level 0s in one Project.

Ok, but inserting spot elevation marks will give that trick away, so it won't help in this case.

Spot elevations can be set relative to a level, can't they?

They can be set realative to survey, base point and shared coordinates as far as I know.
