Creating partitions in activity diagrams

In activity diagrams, you can use partitions to group activity nodes and edges. An activity node can be referenced by one or several partitions.

Before you begin

When you create a partition in an activity diagram, you can also specify the model element that the partition represents.

An activity diagram must be open in the Modeling perspective.

About this task

To create a partition, in the Palette, under Activity Diagram, click Partition; then click in the diagram.
Tip: You can also add a partition by right-clicking the activity name in the Project Explorer view; then clicking Add UML > Partition.
