■
When adding new walls during a Refedit session, add the existing walls to the current working set. Select the Xref
cleanup group of the existing walls for the walls you are adding. Otherwise, the new walls do not clean up with
the existing walls until you save changes to the drawings.
■
Use the Regenall (Regenerate All) and ObjRelUpdate (Object Relationship Update) commands to update the
relationships among walls in the drawing, especially if you move or transform walls involving xref drawings, or if
you undo edits to walls in an xref drawing.

“
Troubleshooting Wall Cleanups ” on page 692.
Xref Drawing with Walls from Host Drawing
My xref drawing contains copies of walls that are in my host drawing. How did this happen?
If you added objects, such as doors or windows, to a wall in the host drawing while you had a Refedit session open for
an xref drawing, a copy of the selected wall is added to the xref drawing. This occurs because any objects added during
a Refedit session are always added to the xref drawing and not to the host drawing. Because the object you added was
anchored to a wall, the wall is also added to the xref drawing.
To correct the drawings, review both the host drawing and the xref drawing for duplicate objects. Remove the duplicates
from the incorrect drawing files. Allowing the duplicates to remain can create problems with the cutting of walls around
doors, windows, door/window assemblies, and openings. Hidden line and shaded views are also affected.
To avoid creating duplicate objects in xref drawings, do not add or edit objects in the host drawing when a Refedit
session is open for an xref drawing. Also, instead of opening a Refedit session, you can open the xref itself, and make
edits directly. You can then save the xref drawing, and reload the updated drawing in the host drawing.
Adding a Door in an Xref Drawing
I added a wall in an xref drawing and then added a door to the wall.The door does not center correctly.
What causes this, and how I can correct it?
Some changes that you make during Refedit sessions of xref drawings do not take effect until you save the changes to
the xref drawing. When you add doors, windows, door/window assemblies, and openings to a new wall in an xref
drawing, their placement is affected by whether the new wall cleans up with other walls in the drawing. Clean up does
not occur between walls in xref and host drawings until you save the changes in the Refedit session.
For best results, if you add walls during a Refedit session, save and close the session before adding objects to those walls.
Open a new Refedit session (or open the xref drawing directly, outside of the host drawing), verify that the walls clean
up as you intend them to, and then add objects to the walls.
Cleanup Group Definitions
A wall cleanup group definition is a designation that you can assign to wall styles and individual walls to control how
intersecting walls clean up. Walls that belong to the same cleanup group clean up where they intersect according to
the priority assigned to each component in each wall. Walls that belong to different cleanup groups do not clean up
when they meet at corners or intersections.
Walls that do and do not clean up
Controlling Wall Cleanup through Design Rules
You use the design rules of a cleanup group definition to determine how walls assigned that cleanup group cleanup
when you Xref them in other drawings. The setting for this design rule in the cleanup group definition in the xref
drawing controls whether those walls clean up with walls in the host drawing.
Design rules also determine whether you can move or copy objects from walls assigned to other groups to walls assigned
to the current cleanup group. Preventing copying or moving objects to walls in a certain cleanup group helps you avoid
inadvertently placing objects in walls that should not contain them.
