The following issue was submitted to Bentley Technical Support. This issue has been transferred to this forum so that the community can benefit from the troubleshooting techniques and resolution.
I'm calculating the volumes of two surfaces and I need to generate a cut and fill map. I calculated the volumes, how do I generate a cut and fill map?
We have the ability to generate an Isopach Surface through Surface > Design Surface > Generate isopach Surface which will create a cut/fill surface between an existing and design surface. with this command you can display the symbology for the Staking of the points generated in the Isopach surface by displaying cut and fill symbologies which will be cut/fill between the surfaces. This will show the areas that are in cut and in fill as well as the cut and fill depth.
If this doesn't answer your question, can you ellaborate on what you are looking for with the cut/fill map?

With that Cut/fill surface Chris mentioned you may draw: "Color-Coded Elevations (Surface/View Surface)
But Chris? Where do we get areas (shapes) for cut and fill with "Generate isopach Surface"???
For me, this whole workflow is OK but slow and with to many steps.
It is stacked by other Civil-Products from competiors to Bentley to one smooth business workflow, where you get:
1. Cut and fill Areas and area report.2. Cut/fill Surface3. very important: a common boundary of both surfaces4. a report for every cut/fill triangle calculation!
with three clicks:1. Choose the existing Surface2. Chosse the second Surface[ choose preferences (maybe already done, by configuration files )]3. click "Start", get the results 1 to 4, from above
There are CR's to get this straight workflow from InRoads in one single step.

This contour is the point where the two surfaces intersect. It will not give you a true cut shape or fill shape throughout the entire surface but it will allow you to see the intersecting point and be able to generate the shapes if desired from the 0 elevation contour and the boundary.

Is there another way to easily display the "0" contour if the "Evaluation > Hydrology and Hydraulics > pass Through Contours" tool is not an available add-on on my version? I am running PowerSurvey V8i (08.11.09.674). I am trying to show that 18 inches of soil has been placed on top of the existing contours; I was told to run the Isopach command and am stuck in the final steps.

I guess that you can display contours with PowerSurvey, can't you?Try to go to surface, View Surface, View Contours then go to Advanced Tab, and set Elevation limits (high and low). Alternatively you can display all contours and delete all which are not at 0.0 elevation.
Take notice that I can not check whether that that will work with Powersurvey as I am running InRoads.

The PowerSurvey SS2 DTM tools are the same as InRoads SS2, but not all are available.
After doing the isopach command, the resulting DTM can be displayed with "Display contours" . If the first and second DTM are really cutting themselves, then the 0-Zero contour can be displayed only when setting a huge intervall value, like 1000.
There is a open CR for doing:
