I have always been frustrated with the way that Civil 3D preforms an Elevation Surface Analysis. This is a great tool, however, the process of running the analysis has always seemed cumbersome to me. There has never been a way to set an interval for the elevation bands or a starting elevation for the bands. The only option was to set a number of ranges and then manually edit the ranges that Civil 3D automatically created for you. This was a tedious and frustrating process. Civil 3D 2012 finally gives us some options to make this much easier.
