How to refine topography in Leapfrog with a pit or excavation design.

Objective:

I need to refine my original topography with a designed excavation such as a open pit or other surface ground works.

 

Resolution:

In order to complete this resolution you will need  topography and design meshes (open) that goes above the topography.

  1. Clip the Design mesh with the original topography (You do this here to make sure the edge of the mesh is on the topography used in Leapfrog and not another software)
    • Meshes->Mesh Operation->Clip Mesh
    • Clip: Design Mesh
    • Using the original Topography
    • Retain the outside (double check that the correct one is retained)
  2. Repeat for each design mesh object.
  3. Merge the topography with the design mesh(es)
    • Meshes->Mesh Operation->Merge Meshes 2D
    • Select the design mesh(es) as the "Detailed Meshes"
    • Select the original topography mesh as the Base Mesh
    • Leave the buffer and resolution on the default.
  4. Export or use this new Mesh as the topography.
