Save Back Edited Xrefs and Blocks
While editing a block reference in place, you can save back or discard changes
made to the reference. If you save back changes to a reference, AutoCAD
regenerates the drawing.
When AutoCAD saves back changes, the block definition is redefined and all
instances of the block are regenerated to reflect the changes. If you choose to
discard the changes, the working set is deleted and the block reference
returns to its original state.
Similarly, while editing an xref in place, you can save back or discard changes.
Objects in the working set that inherit properties not originally defined in the
xref retain those new properties. For example, an xref contains layers A, B, and
C, and the drawing that references it contains layer D. If new objects are drawn
on layer D during in-place reference editing and changes are saved back to the
reference, AutoCAD copies layer D to the xref drawing.
If you remove objects from the working set and save changes, the objects are
removed from the reference and added to the current drawing. Any changes
you make to objects in the current drawing (not in the xref or block) are not
discarded. If you delete any object that is not in the working set, the object is
not restored even if you choose to discard changes. You can return the
drawing to its original state by using
UNDO. If you make unwanted changes
to an xref and use
REFCLOSE to save back the changes, you must use UNDO to
undo any changes made during the reference editing session. After you have
undone any unwanted changes, use
REFCLOSE to save changes to restore the
xref file to its original state.
Warning! While editing a reference in place, if you delete an object that is not
in the working set, the object is not restored if you discard changes at the closing
of the reference editing session.
