Hi all,
I am practicing for using Grading Optimization in Civil 3D. Due to site condition, the optimization result always create output like picture 1 Civil3D output (component follow the surface level to achieve optimized cut and fill volume).
Is there any way to "force" the road level below surrounding building pad (like picture 2 User expectation) while still optimize cut and fill volume?
Offset Points from the GO Grading Objects tool palette will force a min and max elevation difference range from the start point to the end point. So you could use that applied to a polyline drawn from the road to the middle of the building pad to force the positive elevation difference. Better to use multiple polylines along the section of road near the building pad. If you do as Tim mentioned above it shouldn't change the elevation of the road... or you could use a pathway for the road if its elevation is flexible.
