Using the lay-out option (UML 2 diagrams only)
The lay-out option in a UML 2 diagram is used to intelligently graphically organize the selected elements.
To activate the lay-out option,
simply select the elements you want to lay out graphically and click on the
icon in the UML 2 diagram toolbar on the top
right of the diagram. The selected
elements are then graphically arranged for optimum diagram legibility.
