Diagram Panel

The 'Diagram' panel contains a set of facilities for creating and managing diagrams and the elements they contain. Diagrams are a way of presenting and visualizing a model's elements and their connections. They can be enhanced by a range of overlays that transform the diagram into an expressive view such as a Kanban board, a Roadmap diagram, or swimlanes, which allow elements to be allocated to different aspects such as responsibility or ownership. A diagram can also be viewed in a number of other formats, such as a list of elements or a Gantt chart describing the allocation of resources to the elements.

  • Configure Z Order - display the 'Modify Z Order' dialog, on which you set the Z order of each element on the diagram
  • Make all Elements Selectable - click on this option to make all the elements on the current diagram selectable, so that they each can be worked on

If an element is:

  • Selectable, you can move it around the diagram and perform right-click context-menu operations
  • Unselectable, you cannot move it around the diagram and the only right-click operation available is to make the element selectable

The 'Make all Elements Selectable' option has no effect on double-click operations on the element, such as displaying child diagrams.
