If this option is checked, all the objects in the selected reference will be
automatically included 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.
Display Attribute Definitions for Editing
Controls whether all variable attribute definitions in block references are
extracted and displayed during reference editing.
If Display Attribute Definitions for Editing is selected, the attributes (except
constant attributes) are made invisible, and the attribute definitions are
available for editing along with the selected reference geometry. When changes
are saved back to the block reference, the attributes of the original reference
remain unchanged. The new or altered attribute definitions affect only
subsequent insertions of the block; the attributes in existing block instances
are not affected. Xrefs and block references without definitions are not affected
by this option.
Lock Objects Not in Working Set
Locks all objects not in the working set. This prevents you from accidentally
selecting and editing objects in the host drawing while in a reference editing
state.
The behavior of locked objects is similar to objects on a locked layer. If you
try to edit locked objects, they are filtered from the selection set.
