Activity Diagram Toolbar

Use the activity diagram to model system dynamics.

You can model activity diagrams using either UML 1.4 or UML 2.0 features.

UML 1.4 Elements

By default, Together uses the UML 1.4 specification for modeling diagrams. To enable UML 2.0 support, see Enabling UML 2.0 Features.

The toolbar below reflects the default UML 1.4 features for an activity diagram in Together:

Buttons

Button	Description
	Activity: Draws an activity element.
	Decision: Draws a decision element.
	Signal Receipt: Draws the signal receipt element.
	Signal Sending: Draws the signal sending element.
	State: Draws a state element.
	History: Draws a history element. Place history elements inside of state elements.
	Object: Draws an object element.
	Start State: Draws a starting state element.
	End State: Draws an ending state element.
	Horizontal Fork/Join: Use to draw multiple horizontal transitions.
	Vertical Fork/Join: Use to draw multiple vertical transitions.
	Swimlane: Draws a swimlane element.
	Transition Link: A transition link can be drawn only between state elements on the state diagram.
	Object Flow: An object flow link can be drawn between activities, decisions and signals.

UML 2.0 Elements

By default, Together uses the UML 1.4 specification for modeling diagrams. To enable UML 2.0 support, see Enabling UML 2.0 Features.

The toolbar below reflects UML 2.0 enabling for an activity diagram in Together:

Buttons

In addition to Decision, State, History, Object, Fork/Join, and Object Flow elements described above under the UML 1.4 Elements section, enabling UML 2.0 gives you the following additional elements:

Button	Description
	Activity Invocation: Formerly known as the activity element. Draws an activity invocation element on the diagram.
	Initial Node: Formerly known as the start state element. Use initial node to indicate the initial state on an activity diagram.
	Activity Final: Formerly known as the end state element. Use activity final to indicate the final state on an activity diagram.
	Control Flow Link: Formerly known as the transition link. Use the control flow link between state elements on an activity diagram.
	Activity Partition: Formerly known as the swimlane element. Draws an activity partition element on the diagram.
	Flow Final: Use the flow final element from a decision element. Designates either the termination or merge of a flow.
	Interruptible Activity Region: Use this type of grouping to encapsulate activity and decision elements that constitute loops in a process.
	Iteration Activity Group: Use an iteration group to set apart a loop in the flow of an activity.
	Interrupting Edge: Use an interrupting edge to show a non-local termination of flow.
