Frequent tipster Leonid Nemirovsky sends us a command sequence to quickly detach all referenced files in AutoCAD.
"To detach all xref files, type the following at the Command prompt:
All files will be detached, and there is no need for opening a dialog box."
Notes from Cadalyst Tip Patrol: Why waste time with dialog boxes? This series of keystrokes uses the Command line instead of a window. The dash (-) in front of any command will bypass any windows or dialog boxes and use the command line. –XREF lets you access the Xref Manager, but in the Command line. (In the same way, –LAYER lets you access the Layer Manager, but only in the Command line.)
