Layout of Sequence Diagrams

To offset the vertical height of sequence messages to get an attractive and effective layout, follow the steps below




Select the appropriate message in a Sequence diagram


Use the mouse to drag the message up or down as required

As you drag a message up or down a lifeline, any messages or fragments below that message are shifted up or down the same amount; however, be aware that if you drag up or down past the next or previous message, Enterprise Architect interprets that as the requirement to swap positions, rather than simply offset a message position
