Co-Region Notation

Co-Region notation can be used as a short hand for parallel combined fragments. To access the Co-Region submenu, right-click on a connector in a Sequence diagram and select the Co-Region context menu option. There are four sub-options available:

  • Start at head
  • End at head
  • Start at tail
  • End at tail.
