An application for AUTOCAD 2002-2012 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 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.
