About Name Conflicts in External References

When you attach an xref, the names of its blocks, dimension styles, layers, linetypes,
and text styles are differentiated from those in the current drawing.

A typical xref definition includes objects, such as lines or arcs. It also includes
xref-dependent definitions of blocks, dimension styles, layers, linetypes, and text
styles. When you attach an xref, the program differentiates the names of these xref-dependent
named objects from those in the current drawing by preceding their names with the
name of the referenced drawing and a vertical bar character ( | ). For example, in
the Layer Properties Manager, the xref-dependent named object that is a layer named
STEEL in a referenced drawing called stair.dwg is listed as STAIR|STEEL.

When you attach an xref, the definitions of its dependent named objects are not added
to your drawing permanently. Instead, these definitions are loaded from the referenced
drawing file each time you reload it.

Bind Xref-Dependent Definitions

An xref-dependent named object’s definition can change if the referenced drawing
file is modified. For example, a layer name from a referenced drawing can change if
the referenced drawing is modified. The layer name can even disappear if it is purged
from the referenced drawing. This is why the program does not allow you to use an
xref-dependent layer or other named object directly. For example, you cannot insert
an xref-dependent block or make an xref-dependent layer the current layer and begin
creating new objects on it.

To avoid the restrictions on xref-dependent named objects, you can bind them to your
current drawing. Binding makes the xref-dependent named objects that you select become
a permanent part of your current drawing.

When xref-dependent named objects are merged into a drawing through binding, you
can use them the same way you use the drawing’s own named objects. After you bind
an xref-dependent named object, the vertical bar character ( | ) is removed from the
name and replaced with two dollar signs ($$) separated by a number (usually zero):
for example, the referenced layer, STAIR|STEEL, becomes STAIR$0$STEEL. You can then
use the RENAME command to change STAIR$0$STEEL to STEEL.

If you specify a layer whose associated linetype is not CONTINUOUS, the referenced
linetype is also bound. If you apply XBIND to a block, all named objects that are
referenced by the objects in the block are also bound. If the block contains a reference
to an xref, that xref and all of its dependent definitions are bound.
