Removing Unreferenced .shx Files
When you open an electronic drawing file from a source outside your office do you sometimes get a pop-up that AutoCAD is looking for a certain .shx file? Like, "aaa.shx", or "acad.shx"!
Load the lisp routine below into your drawing then type RSHX at the command line.
The program will eliminate that pesky pop-up.
I haven't found a method that works better.
I found this while searching for an answer.
Kudos to the author.
