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.

The RefUcsSpy 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.

This plugin was first published as an ADN  Plugin of the Month. The plugin has been provided with the complete source code needed to build the application, with the intention of encouraging users of Autodesk software to use programming to tailor the products they use to their specific business needs.

More information regarding this plugin can also be found on Kean Walmsley's blog about AutoCAD programming,  Through the Interface.
