AutoDesk Labs has a bunch of cool plugins for AutoCAD. The one that that looks especially useful to me is RefUcsSpy. From the site:
Many AutoCAD users have reference files set up in World coordinates. Attaching such files when in a different User Coordinate System (UCS) can result in the contents appearing at incorrect locations. This plugin can be used within AutoCAD to detect when reference files are being attached when the UCS is not “World.” If it is not, the user will be prompted whether they would like to temporarily set the UCS to World for the duration of the attach command.
