Add Connectors

Connectors define specific relationships between specific elements, so you usually create them directly on the diagram by dragging the required relationship type from the Diagram Toolbox.  As for elements, the Toolbox automatically presents the connector or relationship types appropriate to the type of diagram.

Notes

If you are creating several connectors of one type, after creating the first just click on the appropriate source element and press ( F3 ) to create the next connector of that type
As you drag a connector, you can press ( Shift ) to create a bend in the connector; if necessary, you can put several bends in the connector line, pressing ( Shift ) every time you want to change direction
To roll back the bends, keep holding the left mouse button down and press ( Backspace ) as many times as is necessary
To find out more about the type of connector you have dragged on to a diagram, right-click on the connector and select the UML Help menu option, which displays a Help page on the connector type
