I'm out of my league here but want to learn...
As I understand, with PDM you have a revision scheme and versions. We used to show just the revision of the file (Smarteam days) on drawings. Check in and check out created a new rev/sub rev (01.1 to 01.2 to 01.3 and then released to 01) but with PDM Pro I've been introduced to versions. The current workflow has the versions changing at check in and check out but the revision only changes when a "Status" change happens. I'm not sure why this is the way it is but I don't really care (now anyway).
Does anyone show the revision AND the version on a drawing?
