In
UML modeling, a transition is a relationship between two states in a state
machine diagram. A series of states connected by transitions describes the
various states of an object and the order in which each state is entered.
Before you begin
Before you can add a transition to a state
or pseudostate, you must have a state machine diagram open in the
Modeling perspective.

Procedure
- In the Palette, click Transition.
