Are you missing the Composite Volumes tool in Civil 3D 2014? I like the new Volumes Dashboard but I don’t like creating additional surfaces to calculate earthwork volumes. The command to the original Composite Volumes tool is still in Civil 3D 2014. It is REPORTSURFACEVOLUME. I’ve recreated the ribbon and menu button for this command.
The image shows the location of the two buttons in the provided CUI file.
Here's a link to the CUIX file.
