Detach DWF Underlay Files
Concept Procedure Quick Reference
 
 
 

DWF underlays can be detached from a drawing file.

You can detach DWF underlays that are no longer needed in a drawing. When you detach a DWF underlay, all instances of the underlay are removed from the drawing, the underlay definition is purged, and the linking path to the DWF file is removed.

NoteErasing an individual instance of a DWF underlay is not the same as detaching it. A DWF underlay must be detached to remove the link from your drawing to the DWF file.
