David,
Thanks for the reply, but how does this answer the question? I realize it can be done in the field by a road builder, but how can I alter the model to more accurately depict the way it would need to be done?
Obviously, without retaining walls, we would need to have side slopes that would need stabilization depending on the degree of slope. In this case, one of the challenges is depicting how much of an easement will be required to construct the road, and how much of the site would be taken up by road building.
The side slopes that were generated in my model are near 90 degrees. we know they need to be more like 40 degrees. so more land will need to be cleared and stabilized.
The new grading lines that were auto generated when the road was placed appear in green (see embedded plan image), but cannot be selected or edited. If they could be edited, i could possibly alter the model.
