I have a project where Create Cut Fill Volumes is not working correctly. It seems to be using a different existing ground terrain than what is set as active. The corridor correctly ties down to this terrain. The first image shows the left side of a particular template drop, which is a correct representation. The second image is of the same left side, but with the cut and fill shapes displayed. For some reason it appears to be using a different terrain. The cut volume doesn't extend to the existing ground over the entire section, and there is a phony fill volume that doesn't really exist. This is happening on most, if not all, of the dynamic cross-sections. As a test, I loaded any and all project-related terrains into this view. None of them represent the surface that Create Cut Fill Volumes is using.
What is happening here? Needless to say, at this point I have very little confidence in my earthwork volumes.
