A 'Parallel' construct can be added to an 'Action Diagram' via drag-and-drop.

1. Within an 'Action Diagram,' click the 'Parallel' icon in the 'New' tab of the left sidebar and continue to hold down the left mouse button.
2. Drag the 'Parallel' icon over to the arrow line between the Start and End nodes.
3. When the line between the Start and End nodes highlights green, release the left mouse button to drop the new 'Parallel' and add it to the diagram.
4. The 'Parallel' does not remain selected once it has been dropped. You can now begin to add other diagram constructs to the new parallel branches.
5. To add another branch, select the 'Parallel' construct, then select 'Add Branch' and you will see another branch appear. Add as many as desired by repeatedly clicking the button.
6. Click the 'Save' button located on the toolbar to persist your changes to your project’s database.

* Note: For more information on this construct and how it is represented in the database model, see Action Diagram Constructs.
