This function allows the
user to identify any existing line and its line direction. The selected line is
highlighted and the starting point is labeled with a circle. The subsequent
points are represented with arrowheads and the number of points on the selected
line is printed in the message prompt window.
As illustrated in Figure 5.1.40, two approaches can be used to show a line.
