- Xrefs on their own layer
- Xrefs always unloaded
If we can count on the AutoCAD user being consistent to assign all of the file’s xrefs to a unique layer not shared by any other elements then we can still turn off the overlay xref when it shows up. This shouldn’t be too difficult to achieve and many firms already have that standard for xrefs.
If the xref’s are always unloaded before closing a file then they won’t show up in a Revit project. That’s pretty unlikely. It’s inconvenient for AutoCAD users and forgetting just once and the system fails.
