In sequence diagrams, you can move a lifeline to reposition it
in an interaction frame. Although the horizontal order of a lifeline does
not have semantic value in the project, you can move the lifeline horizontally
to position it in a location that makes the diagram easier to read.
You must have a sequence diagram open that contains lifelines.
To reposition a lifeline, in the diagram editor, click a lifeline
and complete one of the following steps:
- To move the lifeline left or right, drag the selected lifeline horizontally
to a new location in the interaction frame.
- To reorder the lifeline, drag the selected lifeline horizontally across
other lifelines to a new location in the interaction frame.
Tip: To resize a lifeline, click a lifeline and drag
a handle horizontally to extend its width across the interaction frame.
