Bend points
A bend point is added to a connection between two message flow nodes where the line that represents the connection changes direction.
Use bend points to change the visual path of a connection to display node alignment and processing logic more clearly and effectively. Bend points have no effect on the behavior of the message flow; they are visual modifications only.
A connection is initially made as a straight line between the two connected nodes or integration nodes. Use bend points to move the representation of the connection, without moving its start and end points.
