From the developer:
The OffsetInXref plugin can be used with AutoCAD to enable the OFFSET command to work with line contents of blocks and externally referenced drawings, associated arrays, dimensions and tables. Once loaded, the standard OFFSET command will work with blocks and externally referenced content: instead of responding "Cannot offset that object", the plugin will automatically copy the selected object into the current drawing
