Deleting messages

You can delete a message from a specific sequence diagram or from all sequence diagrams and models. When you delete a message, you have different results depending on the type of message that you delete.

To delete a message:
  1. Open a sequence diagram that contains at least two lifelines with messages.
  2. In the interaction frame, right-click a message; then click Delete from Model.
Note:
  • If you select a synchronous message and delete the send message, the corresponding execution occurrence and the return message are deleted automatically. If you delete only the return message, the corresponding send message and the execution occurrence remain in the interaction frame.
  • If you delete an asynchronous message, the send message and the corresponding execution occurrence are deleted.
  • If you delete a create message, the lifeline extends to the top of the interaction frame.
  • If you delete a destroy message, the lifeline extends to the bottom of the interaction frame.
