Diagram View

If you have created diagrams in the Project Browser, you can select to open them and then add elements and connectors to them within the Diagram View. This is the main workspace for developing the structure of your model components, dragging new objects onto the diagram from the Diagram Toolbox and existing objects from the Project Browser. You can also add elements and connectors using the Quick Linker and other context menus within the Diagram View, and move, format and edit them.

Most work on elements and connectors is carried out in the Diagram View, so understanding how it works and how to manipulate elements is essential. You can use the EAExample project supplied with the system, or your own 'sandpit' models, to explore the capabilities and behavior of the Diagram View.

  • Icon and text label for the diagram type
  • Diagram name
  • A vertical 'chevron' icon to display or hide the 'Format' Toolbar

You can hide or reveal this toolbar by clicking on the 'chevron' icon in the Caption Bar (third icon from the right).

Diagram View

The larger area underneath the Caption bar is the work area within which you can create and view the diagram structures. The borders of the printable diagram page are represented by pale broken lines; structures created beyond these borders will print on separate pages.

The Diagram View area is also where the diagram and object context menus operate, and where the representation of the model structure can be changed to a Gantt chart or Diagram List format.

The Gantt View Diagram List


  • Diagrams can contain hyperlinks to other diagrams, which are opened when you click on the links
  • It is possible to open several diagrams at once, but within the Diagram View you can only view one at a time
  • You can view and work on several diagrams at once, by making the tab containing a diagram into a floating window, using the 'Window' menu
  • You can also work on elements using the Diagram List
  • Additional information on the diagram, or a selected element within the diagram, is displayed in the system Status bar
