Drawing fork nodes
You can draw fork nodes in activity diagrams for objects, use cases, and operations.
About this task
Activity diagrams can include join nodes or fork nodes. A join node or fork node depicts either a join operation or a fork operation.
Procedure
- Click the Fork Node button
on Diagram
Tools. - Click, or click-and-drag, in the activity diagram to place the fork node bar at the intended location. Fork node bars can be vertical or horizontal only. By default, the join line is drawn horizontally.
- Draw a source state and an incoming control flow coming into the fork node bar.
- Draw the target states and the outgoing control flows from the fork node bar.
Results
A fork node is shown as a heavy bar with one incoming control flow and two or more outgoing control flow arrows.
