DWG XREF Follow Up

 A year ago I wrote about XREF DWG files showing up in Revit even when they are assigned to Overlay vs Attached. It hasn't been resolved, meaning Revit is still doing it, no change...

Shortly after writing the post we arrived at our "solution", to assign all Xrefs (in AutoCAD/Civil 3D) to a unique layer(s) and turn that layer(s) off in Revit (via View Templates usually). This way the extra layers of the xrefs do not show up even though Revit is technically ready and willing to show them.

Two options exists to work around this situation (last post). One is easy and Revit focused but depends on the AutoCAD user a little and the second is impractical and depends on the AutoCAD user entirely.

• 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.
