Building a dissecting line in parallel through a point
This mode is intended for creation of the linear object located in parallel to chosen piece of the metrics inside of the closed contour (the polygon or closed linear object). The created line is parallel to the chosen part of the metrics and has two points of the metrics which are located on a contour of source object. As a result it turns out that the line as if dissects the source object onto two parts. It is necessary for user to choose source object of a map, thus, the cursor should be placed in area of the piece of the metrics necessary to us. In other words, that piece of the metrics which is the nearest to the cursor of the mouse, and will be used as source piece. After a choice of a source object specify dot object through which a created line should pass.
