Deleting lifelines

In sequence diagrams, you can delete a lifeline to remove a participant from an interaction.

To delete a lifeline:
  1. Open a sequence diagram that contains at least one lifeline.
  2. In the interaction frame, right-click a lifeline; then click Delete from Model. All send and receive messages that originate from the deleted lifeline and all interaction fragments that cover the lifeline are deleted. The combined fragments and interaction occurrences that cover other lifelines are not deleted.
