  • Open a new file and navigate to the “Insert” tab. From the “Shapes” menu, add all shapes that represent the objects, lifelines, messages, and activation bar.
  • Once every element is inserted, label the messages and returning messages to clearly visualize the processes of the system.
  • After you create a sequence diagram structure, you can add your personal touch to it by customizing its properties.
