Adding a Logical Connection

Last modified on October 27th, 2014.


A 'Logical Connection' can be added in the 'Class Diagram' via drag-and-drop. The example used on this page connects two (2) 'Class' constructs with a 'Logical Connection'. Below is an outline of the necessary steps:

  1. Within an 'Class Diagram', select the 'Class' you would like connected to another 'Class'.

    Select Class

  2. Click the green circle and continue to hold down the left mouse button.

    Click New Logical Connection

  3. Drag the green circle over to another 'Class' of your choice.

    Drag New Logical Connection

  4. When the parent 'Class' box highlights green, release the left mouse button over the 'Simple Association (connected by)' section to drop the new 'Logical Connection' and add it to the diagram.

    Drop New Logical Connection

    Notice the 'Logical Connection' stays selected once it has been dropped. Since it is selected, the toolbar changes to include buttons for functions which can be used on the construct. The sidebar also changes to include additional 'Attributes' and 'Metadata' tabs.

  5. Once added to the diagram, enter a meaningful 'Name' for your new 'Logical Connection' via the 'Attributes' tab of the left sidebar (focused automatically for convenience).

    Name New Logical Connection

  6. 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 Class Diagram Constructs.
