In sequence diagrams, you can add and remove lifelines
that are covered by an interaction fragment, which includes combined
fragments and interaction occurrences. When you remove a covered
lifeline in a combined fragment, all messages and interaction fragments
that were contained in the combined fragment and were covered by
the lifeline are also deleted.
To add or remove a covered lifeline in an interaction
fragment:
- Open a sequence diagram that contains at least
one interaction fragment with multiple lifelines.
- In the interaction frame, right-click an interaction
fragment; then click Covered Lifelines and
complete one of the following steps:
- To add a covered lifeline, click Add
Covered Lifelines.
- To remove a covered lifeline, click Remove Covered
Lifelines.
- In the window that opens, click a lifeline and click OK.
