Rotate a grouped bulding in Revit

[maria_trialversion20]

Hello there, I am trying to rotate an entire grouped building so I can copy it and paste it onto a separate site model. However, after grouping and selecting rotate I get the following message:

'Can't change plane of the Floor Sketch' and the command will not rotate anything. 

Any idea how I can correct this?

I would really appreciate your help. 

Kind regards

 better to Link the Project into another Project, rotate there and then Bind Link...and Ungroup if you really want.  

....just to be clear: if you are merely trying to place your building into another Project having the Site, then Link only (don't Bind), rotate Link into position, and the save the Building's position/orientation on the Site by Publishing the Site Coordinates to the Building Project.
