Hi Can anyone help. I'm using Revit Lt to create a master plan of 40 homes (of several types and sizes). I thought the simplest way to do this would be to link revit files, but then they do not render and just show as grey.

My second plan was to create groups, but then it wont let you alter the level of a house without making that group independent. This seems like a bit of a flaw of the software.

Has anyone else experienced the same problem? Any advice would be much appreciated.

Thanks,

James
