Topography in AutoCAD, triangulation, isolines, volume, sections

An add-on for AUTOCAD or BricsCAD (http://rcad.eu/triangulation-autocad/) which makes the triangulation of a set of POINT entities, the intersection curves (isolines) between a set of 3DFACE entities and a set of equidistance plans, horizontally or vertically and the volume and center of gravity of a set of bodies or between surfaces composed of 3DFACE entities.
You can also load and draw a file of points having the format: Number X Y Z Code. The drawing of the XYZ files is made with POINT, 3DPOLY, SPLINE or BLOCK entities, according to a modifiable library of codes.
The triangulation is performed on a convex hull of a set of points. You can triangulate million points! The isolines can be interpolated and their colors are according to a drawn legend. The isolines having Z a multiple of a value will be drawn thickened. You can define a clipping parallelepiped for isolines. You can also make the projection over a triangulation of a 2D POLYLINE and generate cross sections and a longitudinal profile corresponding at projection. The POLYLINE may contain arcs. Color-filled contour maps can be also generated.
In addition, you can draw a DWG file in Google Earth, by generating a KML file type. The DWG file can be in any projected coordinate system and from any part of the globe (https://rumble.com/v3xe654-export-dwg-3d-to-google-earth-in-topography-in-autocad-or-bricscad-software.html).
You can also import and export LandXML file type.
It is also possible to determine the flatness of the surfaces.
