Use splines to add map features that contain curves. You can draw splines with
varied line colors, weights, and styles, including lines that reflect actual map line
types.
Note As you draw a spline, points are entered in much the same way as those
entered when creating a line. The difference between a line and a spline is that when
you enter each point, the line segment between the points curves instead of staying
straight.
