Is it possible to clip a mesh (representing excavation for a bridge pier) to the existing ground surface (terrain) or triangles[View:/cfs-file/__key/communityserver-discussions-components-files/5922/3D_2D00_Excavation_5F00_test.dgn:940:0]?
I want to turn the excavation mesh into a terrain model and use analyze volumes to figure the excavation quantity.
