In sequence diagrams, you can link lifeline objects and create messages in a sequence in
which the interactions happen.
Procedure
- Select the source lifeline. A menu for the lifeline is displayed. Also, the connector magnet
points for the lifeline are visible down the length of the lifeline, which can be used to connect to
another lifeline within the sequence diagram.
To connect to another object that is outside the sequence diagram shape, you can use the link
option in the menu.
- Click the magnet in the source lifeline that you want to link from. A menu appears with the list of existing lifelines as destinations that you can link to.
- Click the destination lifeline to create the link.
The link between the source and the destination lifelines is created.
