I want to generate a report by sample line station that gives me the cut/fill quantities between my assembly(s) sub-base links and the existing ground. I have section sheets cut with sample lines and the EG surface DREF'd. Am I correct in assuming that you need to create the sub-base surface, (for every corridor, I have 18), to be able to get the cut/fill volumes? The corridor is Xref'd into the section cut sheets, so no hope of generating a surface in the cut sheets from the corridor. Can you have the EG surface defined in the Edit Material List and the sub-base as a corridor shape and get the cut/fill volumes? I have tried and I get zeros in the earthworks report. What am I doing wrong?
