Command button, and then click the Function Edge (Control Flow) or Function Edge (Object Flow) that realizes the Command.From the dialogs that appear, select the conveyed classifier, the source element of the Command, and the destination element of the Command.
The direction of the Command is set to the direction of the Function Edge (Control Flow) or Function Edge (Object Flow).
To define that a Command is realized by a Function Edge (Control Flow) or Function Edge (Object Flow):
• Drag the Command from a Modeler pane to the Function Edge (Control Flow) or Function Edge (Object Flow) on the diagram.

Function Action button, and then click in free space or within a containing element on the diagram. From the Select Type dialog, create or select the Function that is invoked by the Function Action.• From an appropriate Modeler pane, locate the Function element that is invoked by the Function Action, and then drag that Function to free space or within a containing element on the diagram.
Modeler creates a Resource Input Pin or Resource Output Pin to represent each Resource Parameter of the Function that is used as the type of the Function Action.
If you create the Function Action within a Function Partition, Modeler creates an Is Capable Of Performing relationship between the system resource that is represented by the Function Partition and the Function that is selected as the type of the Function Action.
On the Items tab of a Function Action element's property pages, you can view and navigate to the Function that is invoked by the Function Action through the Linked Item association.
