• Through a Structure Diagram toolbar button.

You can add existing items and links to a Composite Structure Diagram in the following ways:
• Through populate commands available on the diagram background and symbols.

To drag an item to a composite structure diagram:
1. Open the Composite Structure Diagram.
2. In an appropriate pane, locate the item you want to add to the Composite Structure Diagram.
3. Drag the item from the appropriate pane to the Composite Structure Diagram.
To add an item through a composite structure diagram toolbar button:
1. Open the Composite Structure Diagram.
2. On the Composite Structure Diagram's toolbar, click the appropriate button for the item you want to add, and then on the diagram, right-click the diagram background.
3. From the Select Object dialog, select the item you want to add to the diagram.
To add items and links through the populate commands:

If you populate a link type and the linked item does not appear on the Composite Structure Diagram, Modeler adds the linked item to the diagram.
