Our firm is working with another architecture firm on a project on which we are linking in each other's Revit files. Our structural consultant is also using Revit and we are linking this file in as well. Recently we have been getting an error stating, "Revit could not find or read 2 referenced files" and "Nested Link."

I suspect that we are getting this message because of circular links. When we receive updated Revit files from our consultants do I need to remove the link to our file first and detach the file from central? What is the proper protocol for preparing a consultant's file before linking it into your own Revit file?

Thank you in advance!
