■

Enter s (Switch) to switch between decision points.

■

Enter b (Backup) to back up to the previous vertex.

■

Enter r (Rollback), then click the vertex to which you want to roll
back.

■

Enter d (Direction), then click the direction you want the follower to
proceed in. You do not have to click on the entity, only near it, to
specify the direction.

■

Enter o (Continue) to make the follower continue in the current
direction.

■

Enter v (Vector), then select the vector to follow. You must specify
the first and last vertices of the vector. ProdNameShort follows the
vector entity between those vertices.

■

Enter c (Close) to close the contour by drawing a single segment
between the two decision points.

■

Enter j (Join), then click an existing vector polyline or contour to join
to the current polyline.

■

Press Esc to cancel the current contour and begin another.
