Is there a way to "merge" a Revit model into another Revit model? We maintain a prototype with many many options (please don't mention design options, our set up is far too complicated to be managed with design options). My idea would be to maintain seperate files for the seperate options and appendages of the building complete with geometry, sheets, details, the works. Then when an option is needed, that Revit file complete with sheets could be brought into our base project file.

Any thoughts?
