This module allows you to:
- Create a triangulated surface from selected points.
- Modify a triangulated surface by adding a line between two selected points.
- Change the orientation of a 3D face.
- Add a point in a triangulated surface with 3D faces.
- Remove a point from a triangulated surface.
- Modify the elevation of a point in a triangulated surface.
- Compute the volume between two surfaces.
- Make a modelized suface; creates smoother surfaces than triangulation.
- Apply colors to surface elements by elevation.
- Draw elevation contour lines.
- Insert elevation texts on coutour lines.
- Extrude a surface up or down.
