Adding elements to timing diagrams

You can add new or existing elements to a timing diagram by using the Palette.


  1. In the Palette, click an element to create.
  2. Drag the element into the diagram editor and click to insert the element.
  3. On the dialog menu, select one of the following options:
    • To create a new element, click Create New element.
    • To select an existing element, click Select Existing element and, in the Select Element window, click an element to reference.


Any elements that you add to the timing diagram are reflected in the sequence diagram. However, changes that you make to the sequence diagram are not reflected in the timing diagram. Timing diagrams are not canonical and represent only a partial view of the interaction. You can add existing elements created on the sequence diagram manually.
