■

Backup to the last vertex.

■

Rollback to a previous vertex that you select with the pointer.

■

Specify a direction for the follower to take. This option is useful when the
follower pauses at a “T” intersection.

NOTE When you use the Direction option, it becomes the default option until
another option is used or until the polyline is completed.

■

Continue in the direction that seems most apparent to the follower. This
option is useful when the follower has simply paused at a raster
intersection.

■

Follow a vector entity. This option is useful for following portions of an
image that have already been vectorized.

■

Close the polyline by drawing a single segment between the two decision
points.

■

Join the current polyline to an existing vector polyline.

■

Cancel the current polyline and begin again by pressing Esc.

NOTE To make the most efficient use of the Polyline Follower, you should adjust
the settings on the 

 (page 360) tab on the Raster Design Options

dialog box.

You can use these options to automatically manage layers, linetypes, and
polyline widths for lines created by vectorization tools. Specify a range of line
widths for the raster entity on the General tab of the 

(page 373) dialog box, then assign layer and polyline width values to these
ranges. When a vectorization command is executed, ProdNameShort examines
the raster line width and assigns the values you specified for that width to the
newly created polylines. You can access the Vector Separation Options dialog
box by clicking the Vector Separation button on the VTools General tab of
the Raster Design Options dialog box. For more information, see 

 (page 249).
