I made a copy of an assembly, using "save as" and the adding a suffix. ( as a back up). The already made drawing was referenced t the original assembly.Now I find this drawing has changed all its references to the new files!, without even asking. Do i have to revert them back one by one? How do I avoid this?
You can avoid that in the future by using Pack and Go, changing file names as part of the process, instead of "save as".
