We are a single discipline electrical firm and are splitting single Revit MEP model production between remote offices. The lighting and power production will be done in one office and telecommunications production will be done in a separate (geographical) office. We have a VPN between offices but it takes to long to load the references (arch model, struct model, etc) when saving or opening our Electrical model. Does anyone have any ideas on how we can reference the (arch, struct, etc.) models locally in each office? If we could get the reference paths to work via drive letter instead of UNC path, I think we could do this seemlessly but I don't think Revit will allow this? We have looked into Steelhead from Riverbed but it is out of our budget. Any help would be greatly appreciated.
