Mystery rectangles showing up?

If he doesn't see the waste, show it to him, track the time wasted on
garbage repair then multiply it by the billing rate. Now if you guys are
paid by the hour by the client it's not a waste, but increased profit, which
may be why he chooses not to see it. If he doesn't care, he's part of the
problem.

 

One question I still have. So are people changing their xref colors in
the drawing used as an xref directly, or are they changing them in the
drawing they pull the xref into?

My preference is to never alter a drawing from an outside source in any way.
(If that's possible, given the quality issues we've discussed.) So I
wouldn't go into the xref and change any colors. I would change the
"visibility" of the xref (colors & freeze/thaw status) using the layer
manager in MY drawing, the one in which the xref is attached. Set
VISRETAIN=1 to keep these settings. If you need to re-create the settings in
another of your drawings, you can export/import the layer states.
