Add and Edit Value Lifeline

From the Toolbox drag a Value Lifeline element onto your diagram. The element displays on the diagram.

Edit the Value Lifeline name




Right-click on the element and select the Other Properties context menu option.

The Timeline <name> dialog displays, showing the General tab.



Overtype the Name field.



Click on the Apply button and the OK button.


Sizing and Scale

In the top left corner of a selected Lifeline element are the left and right quick sizing buttons (Quicksize). These buttons increase or decrease the width of the Lifeline element, which in turn controls the scale width of each time unit. By increasing the width of the element you increase the resolution when adding transitions, which makes them easier to edit.
