The process of creating a triangulation is based on the algorithm known as Delaunay’s Triangulation. In this process, the triangles are oriented on the basis of some set technical requirements that cannot really be the best solution or that do not correctly represent the terrain. In order to define how the triangles are oriented, break lines can be used. In any event, once a surface is created, the orientation of two adjacent triangles can be changed manually by changing the common side for the side obtained by joining the vertices opposite it.
Line 1559-1497 generates a break in the contours
Once the above line is inverted, line 1523-1522 is generated and the resulting contour is more correct.
The command has two operating modes for selecting the line to be inverted. The entity can be selected, or coordinates near the line can be introduced. These modes can be altered entering the suitable option in the command line.
When the surface is edited, the new lines can appear in a different color, according to the program configuration. If it is not possible to alter the triangulation, the corresponding message in the command line is printed.
