I'm trying to calculate a volume of soil to be removed from a dig. I have a point cloud with ground shots from existing grade. For the sake of simplicity, let's say I have a square box with (4) walls and a basement slab, dug into the Earth.
Here are my steps:
- Create a TIN surface from the point cloud to represent existing grade - no problem.
- Create a 3D solid from an (around-the-walls perimeter) 2D polyline, extruded upwards by the height of the walls - no problem.
- Align the (uneven) existing grade TIN surface properly near the top of the walls based on a reference elevation point - no problem.
- Use the TIN surface to Slice off the top of the 3D solid, leaving the uneven top surface, square sides, and square bottom - Having trouble here.
I can't seem to use the TIN surface to clip the 3D solid. Help?
I'm also open to more efficient workflows and ideas on how to accomplish, so if I'm doing this the hard way, please advise. Thanks!
