When you create a diagram you can nominate that diagram to be the 'Home Diagram' for the model, this by default will be the first diagram displayed when you open your model and the landing page for the published model.
This may be a General Diagram; for example: an overview of the Divisions within a business, an Organization Chart, or any other type of diagram such as a Process Area Diagram.
To set the Home Diagram:
- Open the appropriate diagram so it is displayed in the Main Area
- Right-click the diagram then select Other > Home Diagram from the popup menu
Note: if another diagram is already designated as the home diagram you will prompted to confirm the change - click Yes
