Calculate the volume with both sides of uneven rock surface in excavation pit

Hi,

At my job site, they is about 20meter height of uneven rock surface in the excavation pit.

To calculate the volume ,I need to include this uneven rock surface wall.

For doing so,The sharp edge will displays in the cross section.

Because the uneven surface, I cannot create the surface with normal step.The TIn line will joins horizontally,not in vertical direction as is intended.

So how to solve it?

Thank in advanced.

Civil3d surfaces cannot have vertical TIN lines, and cannot have overhangs so it may not be possible to calculate volumes using the data you have.
