ProjectWise provides integration with the Open Reference (XOPEN) and Edit Reference In Place (REFEDIT) commands, both of which allow you to edit references by selecting them from inside the master DWG. Use Open Reference when you need to make significant changes to your external references; this command will open the reference in a new window. Use Edit Reference In Place when you only need to make minor changes to your external references; this command lets you edit the reference directly in the master drawing.
