Triangulation creates a SubDMesh, Polyface Mesh or 3D Solid from a set of points using a Delaunay triangulation algorithm.

General Usage Instructions

The application creates a ribbon panel in the “Add-Ins” tab, which features 3 buttons arranged in a drop-down list:

  •  TriangS3d - creates a 3D Solid
  •  TriangSubdM - creates a SubDMesh
  •  TriangPfM - creates a Polyface Mesh

The command-line commands with the same names are also available.
After a command is invoked, the applications ask the user to select a set of points. If TriangS3d is invoked, it will ask for a Z coordinate for the reference plane, which is needed to close the 3D solid. The reference plane will be parallel to the World XY plane.
After the selection, it creates a 3D polygonal representation of the set of points.
The created 3D object is useful for creating sections, toposurfaces, and calculating the volume of excavation, etc.

Known Issues

Polyface Mesh is limited to 32,767 points – this is an Autodesk® AutoCAD® limitation. The Triangulation of SubDMesh and 3D solid is limited to 200,000 points due to performance and memory usage considerations.
