The Outline view display a structural view of the contents of the diagram, and permits “drilling down” into detailed information on various drawing objects. Alternatively, it can display the complete diagram as a miniature image independently of zoom and panning in the main editor window. This aids navigation and zooming and panning operations in large diagrams, or in diagrams that are zoomed-in.
The Properties view permits configuration of properties for various drawing objects that can be selected in the drawing editor.
