Changing the direction of an io flow on a diagram
When an IO Flow is realized by an Association and on a diagram the IO Flow is shown on that Association, you can change the direction of the IO Flow to that of the Association.
To change the direction of an io flow on a diagram:
• On the Structure Diagram or Class Diagram, right-click the IO Flow that is shown on the Association, and then click Reverse Direction
Modeler reverses the direction of the IO Flow
