To create and assign a behavior

There are two ways to create and assign behaviors, so do one of the following:

• Create a behavior in the element's Specification Window.
  1. Open the element's Specification Window and click the Behaviors property group.
     
     
  2. Click the Create button and then from the menu, select the behavior type.
     
     
  3. In the behavior's Specification Window, specify the behavior and click Close.
• Right-click the element in the Model Browser, on its shortcut menu, click Create Diagram and then click to create Activity, Sequence, State Machine or other behavior diagram.
