Resizing interaction fragments

In sequence diagrams, you can horizontally resize any interaction fragment, and you can vertically resize a combined fragment.

To resize an interaction fragment:
  1. Open a sequence diagram that contains at least one combined fragment with multiple lifelines.
  2. In the interaction frame, click an interaction fragment.
  3. Complete one of the following steps:
    • To resize an interaction fragment horizontally across lifelines, click an interaction fragment and drag the handles left or right across additional lifelines. In the Add Covered Lifelines window, click a lifeline and click OK. The interaction fragment resizes to the new position and covers the selected lifelines.
    • To resize a combined fragment vertically, drag the handles up or down across any messages and other interaction fragments on the same lifeline. The combined fragment resizes to the new position and the covered messages and interaction fragments are reparented to this resized combined fragment.
