Move this shape to the back via the Arrange tab in the format panel. This region surrounds actions that are allowed or able to be interrupted. Interruptible activity region: large rectangle with rounded corners and a dashed outline. ![]() Note: comment shape - a rectangle with a folded corner. Object: rectangle with square corners, to hand an object to another action. Finally, drag connectors between the shapes - you can connect to shapes in other lanes.Īction: rectangle with rounded corners, may link to detailed sub-activity diagrams on another page within the same diagram.Hold down Alt or Option as you drop to overlap the shape without adding it to the lane.If you move that swimlane to another position or resize it, the shapes it contains will move with it. Drop a shape into a swimlane when the outline is purple to add it to the lane.These are called partitions in the UML standard. Swimlanes: container shapes with multiple collapsible lanes, vertical or horizontal, from the Advanced shape library. Shapes used in UML activity diagrams - open this reference in our diagram viewer The shapes used to draw activity diagrams are similar to those use to draw simple flowcharts. Click Insert to add the template to the drawing canvas.Select the UML category, then select an activity diagram template.Select Arrange > Insert > Template from the menu.Click Apply to return to the diagram editor.Enable the UML 2.5 and UML shape libraries in the Software section.Click on More Shapes at the bottom of the left panel.The older UML shape library also contains some useful shapes. Shapes for activity diagrams are in the General shape library and its Advanced sub-library (enabled by default), and the UML 2.5 shape library. Go to our online version of draw.io or open the draw.io desktop app or any of our integrations to create a new activity diagram. They are similar to basic flowcharts and are easy to draw and read. They show a timeline of the sequence of messages passed and received.Īctivity diagrams show the flow of control in a process - the order of execution of actions to complete that activity. Sequence diagrams show the message flow between objects. What’s the difference between activity and sequence diagrams? You can model the behaviour of physical and digital systems, as well as business process flows with activity diagrams. ![]() ![]() UML activity diagrams show the sequence of actions and the flow of control in a system or a process.
