On the theme of new features for the Vault 2012 products, a significant enhancement has been made to user workflows. While you are working within Inventor or AutoCAD based product in a Connected Workgroup (Full Replication) environment, you can request ownership without leaving the application.
Within the add-in, ownership can be requested for the workgroup you are logged into. Users can request, extend, or release ownership of the files you currently have open in the CAD application. This tight integration allows users to remain within their CAD package, saving time, and streamlining workflows.
