Delete contour lines - MDT25

6.9 Delete Contour Lines

This command simply deletes contour lines and their corresponding labels after first asking for confirmation.

When one is working with a very large drawing, it is possible that the editing of surveying points is too slow due to automatic contouring. In such cases it is a god idea to delete the contouring and probably to destroy the current surface in order to generate the contours again later once the editing has been completed.
