I have a site plan drawing with a building where an external stair is being changed to an internal stair. The external stair was drawn as an xref and attached to the site plan drawing. This xref cannot be detached: "Unable to detach. Multiple references detected."
I searched here and on Autodesk's site, and found two known causes of this error: (1) the xref occurs in more than one layout, and has to be erased from all but one layout before it can be detached, or; (2) the xref is nested inside another xref attached to the parent drawing. My site plan drawing has only one layout, with no insertions of the problem xref; in fact, there are no insertions of it in model space, either (they were all erased), so condition (1) isn't true.
As for condition (2), the Xref Manager does not show the xref attached to any other drawing in the tree view - the tree view only shows it attached directly to the site plan drawing. Just to make sure, I used Etransmit to copy the site plan drawing and all its xrefs to my C: drive, stripping out all the paths, and then opened each dwg file to see if it referenced the problem xref. None of them, except the site plan itself, show the xref in the Xref Manager.
Anybody have any ideas what could be going on here?
Thanks,
