Whenever you modify and save an externally referenced drawing in a network
environment, other people can access your changes immediately by reloading
the xrefs in their open drawings.
Receive Notification of Changed Xrefs
When you attach xrefs to a drawing, the program periodically checks whether
the referenced files have changed since the last time the xrefs were loaded or
reloaded. The XREFNOTIFY system variable controls xref notification.
By default, if a referenced file has changed, a balloon message is displayed
near the Xref icon in the lower-right corner of the application window (the
status bar tray). Click the link in the balloon to reload all changed xrefs.
If you close the balloon message without reloading, an exclamation point is
added to the Xref icon. If you click the Xref icon, the External References
palette is displayed.
By default, the program checks for changed xrefs every five minutes. You can
change the number of minutes between checks by setting the XNOTIFYTIME
system registry variable using (setenv "XNOTIFYTIME" "n
") where n is a number
of minutes between 1 and 10080 (seven days).
NOTE When changing the value of XNOTIFYTIME, you must enter XNOTIFYTIME
with the capitalization as shown.
Update Xrefs with Demand Loading Turned On
If demand loading is turned on when you load or reload an xref
With the XLOADCTL system variable set to 1, the referenced drawing is
kept open and locked. No one else can modify the referenced drawing.
With XLOADCTL set to 2, a temporary copy of the most recently saved
version of the referenced file is opened and locked. Others can open and
modify the referenced drawing.
For information about demand loading, see Increase Performance with Large
Referenced Drawings
