Constraints diagram
For information about Constraints Modeling in Modeler, see Constraints modeling overview.
A Constraints Diagram provides a view of the Constraints Model. A Constraints Diagram allows you to quickly create Constraint and Constraint Types, and the relationships between them.
You can create a Constraints Diagram through the context menu of a Package: right-click the Package, and select New > Proprietary > Constraints > Constraints Diagram. Alternatively, if you have configured to display New Diagram in the Quick Access Toolbar, select New Diagram > Constraints Diagram.
The following sections provide information about how a Constraints Diagram is used in the model. For more information about an item, property or model part, click it.
Shows these dictionary items
Like most diagrams, a Constraints Diagram can show variability items and relationships. See Overview of variability items and relationships on diagrams.
For most diagram symbols, you can change the presentation of the symbol through the Style view options (See Style view options - all diagrams), and change the showing of Stereotypes and Tag Definitions through the Stereotypes view options (See Stereotypes view options for a symbol - all diagrams). When a symbol has additional view options for changing its presentation, this icon s shown - to see how the view options can change the presentation, click the icon.

These items (which are not documented in the reference topics) can also appear on a Constraints Diagram:
• Frame Box - provides a way of adding a box or background image to the diagram.
• Link - links items on the diagram. After adding a link, you can add an Event (Event Message) or Operation (Operation Message) to the link.
• Note - provides a way of adding text to the diagram.
• Note Link - links a Constraint, Comment or Note to an item on the diagram.
