Contours are created easily and quickly either from terrain models or from point clouds in Topocad. Contours are created in any contour interval and these are sorted in different layers. Height curves have a special command to put text quickly and cleanly with the choice between the direction of text is selected and if the text is above or on the line.
There are also functions to round contours in varying degrees and with different logarithms. Contours lines are three-dimensional.
