Good Morning all, I would like to lock my dwg file so no one could manipulate it in any way. Or I would like to do something to the file using minsert or something else to make it really have for anyone to use it. Does anyone have any experience with this. Thanks as always for the help.

CADLock is the only sure-fire way.  Anything else can be circumvented by anyone with a few brains and the desire.http://www.cadlock.com/
