DWGLOG is useful in network situations where people are contending for the same drawing files. If you try to open a drawing that someone else is using, AutoCAD indicates that someone else has the file open, but does not identify the person. If all users on your network have logging turned on, you can look at the DWH file to find out who has the file open.
Command: DWGLOG
If you use DWGLOG when logging is turned off, the following message appears:
Logging for drawing files has been turned on.
If you use DWGLOG when logging is on, the following prompt appears:
You are about to turn off logging for drawing files.
Do you wish to continue? [Yes/No]
Logging for drawing files has been turned off.
Type 'dwglog' to turn logging back on.
When logging is on and someone accesses a drawing file, that file's drawing
history (DWH) file is updated. If a DWH file does not exist for that drawing,
DWGLOG creates one in the directory where the drawing file resides. Actions that
are logged include opening a drawing, closing a drawing, and attaching a drawing
as an xref. Following is a sample DWH file:
