Working with Constraints

You can edit constraints in the Constraints property group of the containing element Specification window, in the constraint’s Specification window, or double click the selected constraint and edit it on the diagram pane directly.

In this section, see the following procedures:

Defining a new constraint

To define a new constraint, do one of the following

• In the Containment Tree, from the element shortcut menu, select Create Element > Constraint.
• In the Specification window, select the Inner Elements property group and click the Create button (select Constraint from the list, if needed). Specify the constraint in the constraint Specification window. 

• In the Specification window, select the Constraints property group and click the Create button. In the menu, select a duration, interaction, time, or simple constraint. The constraint Specification window is displayed.

• In the diagram palette, under the Common category, expand the Constraint command and select the Duration Constraint, Time Constraint, or Constraint button and create it directly on the action shape.

Editing a duration interval of the constraint

To edit the duration interval of the constraint

1. Right-click the element shape and select Specification.
2. In the Specification window, select the Constraints property group.
3. Edit the duration interval on the left side of the Specification window in the Specification column.

Applying an existing constraint

To apply a constraint to an element

1. In the chosen element's Specification window, select the Constraints property group and click the Apply button. The Select Constraint dialog opens. 
2. Select a constraint or create a new one.
3. Click OK when you are done.
