I have noticed that if an xref needs repathing then when you open the drawing, you can reload, and unload xref's with Trueview 2015 when the drawing first comes up, because it asks you if you want to establish a new path for a missing xref, and the other items also come up on the screen. I would like to know how to reload and unload xref's with a command after the drawing is already pulled up.
