When you are working with a message flow, and connecting your chosen nodes together to determine the flow of control, you might find that a connection that you have made crosses over an intervening node and makes the flow of control difficult to follow.
To help you to display the message flow nodes and their connections in a clear way, you can add bend points to the connections that you have made to improve the organization of the display. The addition of bend points has no effect on the execution of the nodes or the operation of the message flow.
To add a bend point:
If you want to add more than one bend point to the same connection, repeat these actions from step 4 using the additional small points inserted into the connection.
