Removing covered lifelines from combined fragments

In Unified Modeling Language (UML) sequence diagrams, you can remove covered lifelines from combined fragments.

You must have a sequence diagram with lifelines and combined fragments open in the diagram editor.
To remove lifelines from a combined fragment:
  1. In the diagram editor, right-click a combined fragment; then click Covered Lifelines > Remove Covered Lifeline(s).
  2. In the Remove Covered Lifelines window, click the covered lifelines to remove and click OK.
The selected lifelines are no longer covered by the combined fragment. All messages and interaction fragments that the combined fragment contained and that the lifelines covered are also deleted.
