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.
