Terminating lifelines with stop nodes

In Unified Modeling Language (UML) sequence diagrams, when you create a destroy message, a stop node is created automatically on the lifeline. However, you can manually create a stop node on a lifeline to terminate the lifeline at a specific position.

You must have a sequence diagram with lifelines open in the diagram editor.
To terminate a lifeline with a stop node:
  1. In the Palette, click Stop Node.
  2. On a lifeline, click where you want to terminate the interaction instance.
The lifeline ends at the position of the stop node, which is designated by a destruction marker (X).
Note: You cannot create a stop node above messages or interaction fragments on a lifeline.
