Topic: Capture Project Navigator Command for Drag/Drop for Xrefing

[Guest]

So I'm finally getting into the Project Navigator and one of the things I'd like to do is capture the event when you drag and drop a file from the Views tab into a drawing which then attaches that file as an xref.  I'd like to be able to automatically put the xref onto a company standard xref layer and lock it.

Any thoughts?  Anyone?!?

Matt,
Unfortunately dragging a file from the Project Navigator throws no trappable command.  I use a combination of the Xref Reactor and Modelspace Reactor.  The :VLR-beginAttach fires when the Xref is about to be attached, so I set my XREF layer current.  I couldn't get the :VLR-endAttach to work to re-set the clayer - the database wasn't "released" yet(?) so it wouldn't re-set clayer.  I had to go to the Modelspace Reactor to check when things are attached in modelspace (we rarely attach xrefs in pspace) <edit> it works on paper space too</edit>.  It's a kludge I know - but it works.  Let me know if you find out a better way:

  (setq jb%XrefAttach T)

Would this work for you?

It should fire no matter what space you attach an xref to.  I don't use the project navigator, so I didn't know how to test it out.
