Just wanted to inform you that there is a new extension for AutoCAD Civil 3d 2012 subscription customers.
Volumes Dashboard Extension for AutoCAD Civil 3D 2012 allows you to streamline your Volume iteration workflow.
More info can be found at http://docs.autodesk.com/CIV3D/2012/ENU/contexthelp/VOLUMES_DASHBOARD.htm
Make sure you read the readme file so you know what some of the known issues are.
