Unified Modeling Language (UML) diagrams are easier to
read if connectors do not cross other connectors and shapes. You
can use bend points to customize connector line routing to minimize
crossed connectors in a UML diagram.
To move a bend point on a connector:
- In the diagram editor, select a connector.
- Place the cursor over the bend point that you want to
move until the moving pointer appears.
- Drag the bend point to a new location on the connector.
