Router Icons

Router icons enable you to create routers, which conceal multiple flow lines to make an activity chart more readable. For more information on using routers, see The Router Element.

 
Create Router - creates a router block used within the scope of the top-most activity in a particular activity chart.
Create External Router - creates router blocks used outside the scope of the top-most activity in a particular activity chart. Because activity charts are hierarchical, an external router is always resolved to an internal router in a chart higher in the chart hierarchy.
