Manage Structural Elements
In UML Modeling, you can define certain constructs and events with structural elements (also called Parts, Properties, interaction points or - in the case of Entry and Exit Points on a State element, connection points) that are added on to a parent element. For example, you can add Ports to a Class (as shown), Action Pins to an Action, or Activity Parameters to an Activity. Structural elements become a component of the parent element; certain structural elements (such as Parts and Properties) can exist independent of a parent, but do not have an independent role.
You manage structural elements through the Features window, managing Parts and Properties on the 'Parts / Properties' tab and Ports on the 'Interaction Points' tab. If the parent element is a State, its connection points are shown on the 'Connection Points' tab. All three tabs have the same options, described here.

list of elements |
Review the definition of each structural element currently associated with the selected parent element. If you select the 'Show Owned/Inherited' checkbox, the list will also include any structural elements from any classifiers that the parent element has. If you want any structural element to be visible on the parent element on the diagram, select the checkbox next to that element's name. Notice that the 'Visible' column in this panel then shows the value True against each selected element. To hide the structural element on the diagram, clear the checkbox. The structural element still exists on the parent element, but is just not visible in the diagram. |

Show Owned/Inherited |
The tab lists the structural elements on the selected parent element. If you want to include inherited or owner properties from any classifier that the parent element might have, select this checkbox. |
Notes
- The name of a structural element displays on the diagram as a label, which you can edit using the 'Labels' context menu
