Show Structural Elements In Composite Diagram

A Composite element shows the external relationships of the element with other components of the model and, via a child diagram, its own internal structure. You cannot normally add structural elements to the representation of this internal structure; however, this procedure describes a modified process through which you can add structural elements to the child diagram.

Structural elements include:

  • ActivityParameter
  • RequiredInterface
  • ActionPin
  • Port
  • EntryPoint
  • ExpansionNode
  • ObjectNode
  • ProvidedInterface
  • ExitPoint
  • Part

Include embedded elements in a child composite diagram


Step / Action

Create the element to set as a Composite element. For example, a Class, Activity, or SysML Block.

Right-click on the element in the diagram and select the 'New Child Diagram | Composite Structure Diagram' option.

The element redisplays with a small icon in the bottom right hand corner, indicating that this is now a Composite element.

Composite Elements

Double-click on the Composite element to access the child diagram that it points to.

From the Browser window, drag the Composite element itself onto the child Composite diagram, and paste it in as a Link.

Right-click on the element in the diagram, and select the 'New Child Diagram | Show Composite Diagram in Frame' option.

The element redisplays with a labeled frame around it.

Press Ctrl+S to save the diagram.

Right-click on the diagram tab and select the 'Reload <diagram name>' option.

The diagram redisplays with just the frame showing. This frame represents the original composite element.

Populate the frame with the appropriate internal elements, including the structured elements that attach to the frame itself.
