This BIM 360 forum seems to be the best forum to post this to, since there doesn't seem to be an ACC board.
Regarding the support for old models be removed:
Is there a way to see the version of a model that is in ACC or BIM360? The only way I know is the go into each project and find the "upgrade" tool. This will show the current version.
I have a lot of projects on ACC. I would like to be able to see at a glance which ones are old and need to be upgraded.
To me, it is obvious to me that there should be a column in the ACC projects page that displays the project Revit version. Especially since Autodesk is now saying that all models that are older than 5 versions will be inaccessible, and this will be an ongoing issue for Managers.
