Synchronize Structural Elements - Activity Diagram

If you have already defined the Action Pins and/or Activity Parameters of a SysML Activity element, you can automatically display them on the element's child Activity diagram using a simple context-menu option on the child diagram. 

On an existing SysML Activity diagram, such as this one:

1. Drag from the SysML Activities page of the Diagram Toolbox the Action Pin and/or Parameter icons, and assign the required types to the generated elements during that process.
   
2. Right-click and select 'New Child Diagram | 'Activity Diagram'. Add the appropriate Action element(s) to the diagram.
   
3. On the new diagram, external to the diagram frame, right-click and select the 'Synchronize Structural Elements' option.

These elements are added to the Activity diagram, as linked elements within the diagram frame:

• Each structural element (such as Activity Parameters) owned by the Activity element
• Properties defined by existing Association connectors on the Activity element
• Edge mounted Activity Pins for the Activity
