4.
Point the rubber-banding line in the direction of the new tangent, and pick a point to
indicate the direction of the vertex tangent. An arrow appears, indicating the new tan-
gent direction. (See the second image in Figure 17.15.)
Don't worry if the polyline shape doesn't change. You must use Fit to see the effect of
Tangent. (See the final image in Figure 17.15.)

The Width Option
Finally, you'll try the Width option. Unlike the Pedit command's Width option, the Edit Vertex/
Width option enables you to alter the width of the polyline at any vertex. Thus you can taper or
otherwise vary polyline thicknesses. Try these steps:
1.
Undo the tangent arc from the previous exercise.
