I'm at a firm with two remote offices that are constantly sharing files and updating drawings between each other. Often one person at this office will change a drawing, save it on the network and not tell the other office and then the other office will make edits to the same file, overwriting anything that has been done previously by the first office. Is there a way to avoid having these complications/a better way to share files through a network. Each office has its own license for AutoCad LD.
