So I am having a problem with others messing up my assemblies. I will design a die set from start to finish, get the drawings out to the tool room(where the die set is machined), and somehow everything gets messed up. There are a couple guys out there that are beginner users of Solidworks, and I think they are messing with some small things to make their job easier, even though when they change one small thing it screws up big things. I was just wondering if there was a way to "lock" parts or assemblies so only a select few can make changes. I know we can make everything read only out there, but that would cause huge problems with the foreman. So is there a way to put passwords on the assemblies or something like that?
