These commands enable you to change the Pen style, Line style, Font, Text position and display, and color of symbols you've selected. Using the Symbol Style command, you can set default values for all symbols of a given type, so every time you draw one, it will follow your standards for outline, color, and text font.
Format menu: Diagram format commands
These commands control what non-drawing things are displayed with the diagram: scroll bars, and page markers, for example. You can make all symbols on the diagram have a shadow, to make them look 3-dimensional. You can also set the percentage of reduction for the Reduced View command.
View menu: Display mode command
Controls what properties of a symbol are displayed. For example, entities can display key values, key and non-key values, text description, or physical characteristics.
