Edit a Referenced Drawing in a Separate Window
Concept Procedure Quick Reference
 
 
 

The simplest and most direct method for editing xrefs is to open the referenced drawing file in a separate window. This method gives you access to all objects in the referenced drawing.

Instead of browsing for the xref using the Select File dialog box, you can select the xref and open the referenced drawing. To use this method to edit xrefs, use the External References palette or the XOPEN command.
