Adding create and destroy messages

In sequence diagrams, you can add a create message or a destroy message to a lifeline to represent the creation or the destruction of a participant. You add the create message above any messages and interaction fragments that are covered by the lifeline; you add the destroy message below the messages and interaction fragments.

To add a create or a destroy message:
  1. Open a sequence diagram that contains at least two lifelines.
  2. In the Palette, click Create Message or Destroy Message.
  3. In the interaction frame, complete one of the following steps:
    • To add a create message, click the source lifeline from which the message originates and drag to the target lifeline where you want to create the new participant. The head of the participant aligns with the termination point (message arrowhead) of the message.
    • To add a destroy message, click the source lifeline and drag to the target lifeline where you want to delete the participant.
