The Regen Option
In some cases, the effect of an option does not appear in the drawing immediately. You can
use the Regen option to update the display of the polyline and see any changes you've made
up to that point.
The Straighten Option
The Straighten option straightens all the vertices between two selected vertices. Using the
Straighten option is a quick way to delete vertices from a polyline, as shown in the following
exercise:
1.
Undo the moved vertex (from the previous exercise).
2.
Start the Edit Vertex option again, and select the starting vertex for the straight line.
3.
Enter
S
↵ for the Straighten option.
4.
At the Enter an option [Next/Previous/Go/eXit] <N>: prompt, move the X to the
location for the other end of the straight-line segment.
5.
After the X is in the proper position, enter
G
↵ for the Go option. The polyline straightens
between the two selected vertices (Figure 17.14).

Move the X here; then type
G
to straighten the polyline
between the selected points.
Move the X here; then
start the Straighten option.
The Tangent Option
The Tangent option alters the direction of a curve on a curve-fitted polyline:
1.
Undo the straightened segment from the previous exercise.
2.
Restart the Edit Vertex option, and position the X on the vertex you want to alter.
3.
Enter
T
↵ for the Tangent option. A rubber-banding line appears. (See the top image in
Figure 17.15.)
