Hai,
This is karthik from India. If u enable designer only designers will be able to open the file modife or erase it . excluding designers or design department no one can make any changes in you file so only a perticular person or department will have rights to do any changes. if u enable both designer & draftsmen both have rights to modife or acess your drawing
so u may absorve when u open your software and open a file it askes for a user name & login so you enter user name & login to acess
