About Using the Working Set to Edit References
To edit a referenced drawing from within the current drawing, you use the working set to identify objects that belong to the xref or block definition rather than the current
While editing a reference in place, you can add or remove objects from the working
set. If you create a new object while editing a reference in place, it is almost always
added to the working set automatically. Objects that are not in the working set are
displayed as faded in the drawing.
If a new object is created because of changes made to objects outside the working
set, the new object is not added to the working set. For example, your drawing contains
two lines that are not a part of the working set. If you edit the lines by using FILLET,
a new arc is created between the two lines. The arc is not added to the working set.
When a reference object is part of the working set, you can select the object for
editing even if it is drawn on a locked layer in the reference file. You can unlock
the object’s layer and make changes to the object. Changes made to the object can
be saved, but the layer state remains the same in the reference file, whether it is
locked or unlocked.
An object that is removed from the working set is added to the host drawing and removed
from the reference when changes are saved back. An object that is added to the working
set is removed from the host drawing, and is restored to the reference when the changes
are saved back.
Use the External Reference Tab on the Ribbon
If you select a reference to edit in-place when the ribbon is active, the Edit Reference
ribbon contextual tab is displayed. The editing buttons on the contextual tab (Add
to Working Set, Remove from Working Set, Discard Changes, and Save Changes) are active
only during in-place reference editing. The contextual tab is dismissed automatically
after changes made to the reference are saved back or discarded.
Use the Refedit Toolbar
When the ribbon is not active, the Refedit toolbar is displayed when a reference is
being edited in place. The name of the selected reference is displayed in the toolbar.
The editing buttons on the toolbar (Add to Working Set, Remove from Working Set, Close
Reference, and Save Reference Edits) are active only during in-place reference editing.
The Edit Block or Xref button is active whenever the toolbar is initiated and a reference
editing session is not already in progress within the current drawing. The Refedit
toolbar is dismissed automatically after changes made to the reference are saved back
