In this mode, both the “From” and “To” locations are marked. The marks are placed at a point perpendicular to the shot. Because most "From" stations are also "To" stations, there will generally be two sets of marks at each station. Each one will be at right angles to a different shot. There is also a dotted line connecting each mark with the corresponding station. The size and color of the mark is controlled by the coloring of the normal station mark. This mode of passage modeling is most useful for drawing and tracing finished cave maps.
You have the option of display Crossbars that draw a dotted line between the station and wall markers. You also have the option of displaying the LRUD values next to the mark.
