Setting preferences for UML models

You can set preferences for creating UML models. For example, you can change the appearance of model elements and diagram elements, create path variables to specify a directory location in the file system, or control whether messages automatically create return messages in sequence and communication diagrams. You can also specify preferences for views, such as the Project Explorer view and the Properties view.
