FAQ: How can I get walls to clean up with walls in xref drawings?

here are several actions you can take to improve wall cleanup when you work with xref drawings that contain walls:

• Verify the design rules of the cleanup groups used in the xref drawings. If the cleanup group in the xref drawing does not allow cleanup with the walls in the host drawing, walls in the 2 drawings do not clean up, even when their cleanup groups have the same name.
• 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.
