2012

Displays the reference selected for in-place editing and any references nested
within the selected reference.
Nested references are displayed only if the selected object is part of a nested
reference. If multiple references are displayed, choose a specific xref or block
to modify. Only one reference can be edited in place at a time.
Preview
Displays a preview image of the currently selected reference.
The preview image displays the reference as it was last saved in the drawing.
The reference preview image is not updated when changes are saved back to
the reference.
Path
Displays the file location of the selected reference. If the selected reference is
a block, no path is displayed.
Automatically Select All Nested Objects
Controls whether nested objects are included automatically in the reference
editing session.
Prompt to Select Nested Objects
Controls whether nested objects must be selected individually in the reference
editing session.
If this option is checked, after you close the Reference Edit dialog box and
enter the reference edit state, you are prompted to select the specific objects
in the reference that you want to edit.
Select nested objects: Select objects within the reference that you want to edit
Settings Tab (Reference Edit Dialog Box)
Provides options for editing references.
Create Unique Layer, Style, and Block Names
Controls whether layers and other named objects extracted from the reference
are uniquely altered.
If selected, named objects in xrefs are altered (names are prefixed with $#$),
similar to the way they are altered when you bind xrefs. If cleared, the names
of layers and other named objects remain the same as in the reference drawing.
Named objects that are not altered to make them unique assume the properties
of those in the current host drawing that share the same name.
