3.12. Modify Lines

This command allows one to edit polylines that define break lines, boundary, islands, etc., thereby facilitating and improving the process of moving, inserting or deleting polyline vertices.

Firstly, the program requests the polyline to be modified, and then displays three types of

modifications on the command line:

Move: Displaces the vertex selected to the closest surveying point.

Insert: Adds a new vertex on the section of the polyline selected.

Delete: Deletes the vertex selected.
