Importing use case diagrams

Chapter 9 Working with Object-Oriented Models

The following table maps Rose objects to OOM objects in the following way:

In a Rose model...	Becomes in an OOM
Class with <<actor>>, <<business actor>>, or <<business worker>> stereotype	Implementation class, and actor containing this implementation class (see paragraph below)
Use case	Use case
Generalization	Generalization
Association	Association
Dependency	Dependency

When you import a Rose model containing an actor, PowerDesigner creates:

In a class diagram: a class to recover the operations and attributes of the Rose actor. This class has the same stereotype as in Rose, it is used as implementation class for the new actor.
In a use case diagram: an actor with the class as implementation class
