Use VBA to detach unloaded External References (XREFs)

Often when archiving or sending files to consultants, it is desireable to do some house cleaning prior to transmitting them. A common practice in cases like these would be to detach any unnecessary XRefs. And what is more unnecessary than a previously unloaded xref?

Public Sub DetachUnloadedXrefs()
Dim o_Blk As AcadBlock
For Each o_Blk In ThisDrawing.Blocks
If o_Blk.IsXRef And o_Blk.Count = 0 Then
ThisDrawing.Utility.Prompt o_Blk.Name & _
" is an unloaded xref and has been detached." & vbCrLf
End If
End Sub

Hope you find that useful.
