I am looking for advice or tips on using feature lines for grading purposes. I am working on a project that involves grading a site so that it is entirely in fill due to the client not wanting to cut and having a large stockpile nearby. I have been provided with a drawing that has a EG, FG, and FG volumetric surfaces. I need to play with feature lines to get the cut down to 0 (or very close) and the fill to be approx 125000 m3. I am having trouble getting the feature lines to actually control anything. Any tips?
Is the FGL surface created from a Grading Group (which in turn refers to the Feature Lines)? If so then all you have to do is edit the elevations of the feature lines then rebuild the surfaces.
