Q - question

What is the xref status "Unreferenced"?

A - answer If your External reference palette displays a status "Unreferenced" at an xref, it means that this DWG file is attached to the main drawing but it is not used (referenced) in the drawing - has no insertion point, scale, rotation. This is usually a result of an unintentional erase of the xref instance (reference), improper DWG format of the xref or of another error.

You can delete (detach) such orphaned xref - manually from the palette (right-click), or all - using PURGE or using this XDetach routine:

(defun c:XDetach (/ blk)
  (setq blk (tblnext "block" (not blk)))
  (if (and (cdr (assoc 1 blk))
           (< (cdr (assoc 70 blk)) 32))
    (command "_-xref" "_d" (cdr (assoc 2 blk))))
