Displaying Symbols in Schematics

There are two display styles available for symbols in the Schematic Editor, IEEE and Traditional. The choice between IEEE and Traditional is configured in General tab of the Tools > Options > Schematic Editor Options window.

• Each object in a symbol is associated with a level.
• Graphics on levels 0 and 1 are always present and shown. Graphics on other levels are visible by default, but can be configured as visible/invisible programmatically.
• For IEEE and Traditional styles, all levels are independent — except for level 0 where pins are displayed.
• Both IEEE and Traditional symbols contain at least two active levels, and you may add any number of levels for each style.
