In Unified Modeling Language (UML) sequence diagrams,
you can create an interaction occurrence by specifying a new unspecified
occurrence or by creating a new interaction for visual representation
only.
You must have a sequence diagram with multiple
lifelines open in the diagram editor.
To create an interaction occurrence:
- In the Palette, click Interaction
Occurrence.
- Click inside the interaction frame and, in the window
that opens, complete one of the following steps:
- To create an interaction occurrence with an unspecified
interaction, click Unspecified.
- To create an interaction occurrence with a new interaction,
click Create New Interaction.
- In the Add Covered Lifelines window,
click the lifelines to cover and click OK.
- Type a name for the interaction occurrence and press
Enter.
Tip: To add an interaction occurrence to
a single lifeline, in the Palette, click Interaction
Occurrence and, in the interaction frame, click a lifeline;
then in the window that opens, click Unspecified or Create
New Interaction.
