You can also overlay an xref on your drawing. Unlike an attached xref, an
overlaid xref is not included when the drawing is itself attached or overlaid as
an xref to another drawing. Overlaid xrefs are designed for data sharing in a
network environment. By overlaying an xref, you can see how your drawing
relates to the drawings of other groups without changing your drawing by
attaching an xref.
In the following illustration, several people are working on drawings referenced
by master.dwg. The person working on a.dwg needs to see the work being
completed by the person working on b.dwg, but does not want to xref b.dwg
because it would then appear twice in master.dwg. Instead, the person overlays
b.dwg, which is not included when a.dwg is referenced by master.dwg.
NOTE When using the parametric drawing feature, you can only constrain objects
in the drawing to the insertion point of an Xref, and not its nested objects.
