Adding elements from sequence diagrams to timing diagrams

You can add elements that you created in a sequence diagram to a timing diagram.

Before you begin

You must have a sequence diagram that contains at least one element.


  1. Right-click in the diagram editor; then click Add UML.
  2. On the menu, click one of the following items:
    • Existing Lifelines
    • Existing Messages
    • Existing State Invariants
    Note: Not all options will be available. Lifelines must be created or added before a existing message or state invariant element can be added.
  3. In the window, select the lifelines, messages, or state invariants to add. You can use the Existing Lifelines option to include any state invariants or messages.
  4. Click OK.
