◦ Click the Project Activity Action toolbar button, and then click in free space on the diagram. On the Select Type dialog, create or select the Project Activity that is invoked by the Project Activity Action.
◦ From an appropriate Modeler pane, locate the Project Activity element that will be invoked by the Project Activity Action, and then drag that element to free space on the diagram.
On the Items tab of a Project Activity Action element's property pages, you can view and navigate to the Project Activity that is invoked by the Project Activity Action through the Linked Item association.
On creation of a Project Activity Action, Modeler creates a Project Input Pin or Project Output Pin to represent each Project Parameter of the Project Activity that is used as the type of the Project Activity Action.
Note that after creating a Project Activity Action, Project Input Pin and Project Output Pin elements are not automatically created for new Project Parameter elements that are created on the associated Project Activity.
