Adding an Object Node

An 'Object Node' construct can be added to an 'Activity Diagram' via drag-and-drop. Below is an outline of the steps necessary for adding a 'Object Node' construct to an 'Activity Diagram':

  1. Within an 'Activity Diagram', click the 'Object Node' icon in the 'New' tab of the left sidebar and continue to hold down the left mouse button.

    Click New Object Node

  2. Drag the 'Object Node' icon over to the adjacent diagram canvas.

    Drag New Object Node

  3. Release the left mouse button while over the diagram canvas to drop the new 'Object Node' and add it to the diagram.

  4. Select the generating 'Entity' construct, then click one of the green circles and continue to hold down the left mouse button.

    Click Green Dot on Generating Action

  5. Drag the green circle to your newly created 'Object Node' construct.

  6. When the 'Object Node' highlights bright green, release the left mouse button to add a generated by/generates relationship.

    Release over Object Node

  7. Select your newly created 'Object Node' construct, then click one of the green circles and continue to hold down the left mouse button.

    Click Green Dot on Object Node

  8. Drag the green circle to the receiving 'Entity' construct of your choice.

  9. When the receiving 'Entity' highlights green, release the left mouse button to add the appropriate relationship. Releasing over the "Trigger" section will automatically add the received by/receives relationship with the Trigger relationship attribute, while releasing over the "Optional" section will automatically add the received by/receives relationship with the Optional relationship attribute.

    Release Over Receiving Action

  10. Once added to the diagram with the proper relationship, enter a meaningful 'Name' for your new 'Object Node' via the 'Attributes' tab of the left sidebar (focused automatically for convenience).

    Name Object Node

  11. Click the 'Save' button located on the toolbar to persist your changes to your project's database.

Please Note:
  • The above process describes using the ‘New’ tab of the left sidebar, which automatically generates a new entity to represent each new diagram construct. If you would like to reuse existing entities from your database to represent a new construct, use the ‘Existing’ tab instead.
  • For more information on this construct and how it is represented in the database model, see Activity Diagram Constructs.
