It’s easy to find what drawings are xref’ed into your drawing, but how do you find what drawings your drawing is xref’ed in to?
Ellen Finkelstein has posted a great tip on www.ellenfinkelstein.com regarding how to do this.
Note that you can also use Design Center to search a whole directory, drive, or even a network for drawings containing certain named objects such as layers, blocks, layouts, and dimstyles.
