Introduction - If you have any usage issues, please Google them yourself
This plugin can be used with AutoCAD to manage the state of the
various external references in the current drawing. It allows you to
store "Xref States"- similar in nature to Layer States- which
contain information on the various Xrefs in the drawing: whether
each is loaded or unloaded. The Xref States get stored within the
drawing and so can be used in future editing sessions.
