dont know if this will work......... can you do a SAVEAS on your original drawing, thus retaining xrefs complete with layer settings, etc. Then copy/paste your drawing specific information into it (I'm assuming it already exists). Contrary to opinion, you *can* copy and paste X-ref's between drawings, but as Gordon pointed out, they lose their status as an X-ref when pasted into a different drawing. Remember that Copyclip and Pasteclip is just a quicker was for performing a Wblock and Insert. (You can examine the "copied" drawing in your %temp% directory - the Xref is still there). Note that you would get the same results if you tried Wblock / Insert. One alternative would be to drag/drop the x-refs from DesignCenter
