And that is because how Dietrichs is made (so in princip independent of syncronization software).
There could be another method:
We have a ftp-server. We could use GoodSync to make automatic upload and download of files, on file change level. This - I think - should make it possible to work in the same project at the same time - as long as we work on different positions and different drawings.
Does anybody here, use syncronization of Dietrichs work?
