Grouping state machine model elements into a new composite state

In UML modeling, you can group selected model elements in a state machine into a new state to hide the details of complex state machines.

Before you can group model elements in a state machine into a new composite state, you must have a state machine diagram open in the Modeling perspective.
To group state machine model elements into a new composite state:
  1. Select the states that you want to include in a new state.
  2. Right-click the selection; then click Compose > Aggregate. In the diagram editor, the selected states are displayed inside a newly created composite state. In the Model Explorer, all selected model elements are displayed under the newly created state.
