98 times out of 100, we want access to a previous version, but we want to keep the current one current.
The other 2/100 times, something goes wrong and we want to roll back a version or two, before corruption/catastrophic mistake.
Currently, we have to SAVEAS the current version, roll back to old version, SAVEAS old version. Delete model from C4R. Publish current version. Now all versioning history is gone. Current version = Version 1; old version is detached to server for use. I would like to see Autodesk enable functionality for downloading previous C4R versions w/o rolling back current model.
