This log is maintained only if the XREFCTL system variable is set to 1. The
default setting is 0.
The log file is an ordinary ASCII text file with the same name as the current
drawing and the file extension .xlg. If you load a drawing with the file name
sample.dwg, for example, the program searches for a log file named sample.xlg
in the current folder. If the file does not exist, a new file is created with that
name.
Once a log file has been created for a drawing, the program continues to
append information to it. The program writes a title section to the log file
each time the file is opened. If the log file becomes too large, you can delete
it.
Example: A Sample Title Section from an Xref Log File
This title section contains the name of the current drawing, the date and time,
and the operation being performed.
=============================
Drawing: detail
Date/Time: 09/28/99 10:45:20
Operation: Attach Xref
=============================
During a detaching or reloading operation, the program includes the nesting
level of all affected xrefs immediately following the title section. To see a
reference tree for a set of xrefs in your current drawing, use Detach or Reload
and check the resulting entries in the log file.
