Main idea is an easier way to mirror multiple Revit files (each discipline) that are linked together. I just had to completely remove the links to get Revit to put the correctly mirrored models into the correct spot. Each time I tried to mirror the next model, I had to remove the links so that it did not mirror the linked models that were in the correct location. This is using the tool which mirror's the whole project (Manage,Position, Mirror Project).
