The Symbol Editor
The symbol editor opens when you create or modify a symbol. Like the schematic editor, the symbol editor keeps the placement of symbol elements uniform by snapping them to points on a grid. The window controls for zooming and panning the view are the same as those in the schematic editor.
With the symbol editor, you can add, modify, and manipulate graphical primitives, text labels, pins, and property displays. You can also adjust the resolution, color, and visibility of the editor grid. You can create several symbol levels, which you can use to control symbol visibility. When you’re done, you can update the current project with any changes you’ve made to the current symbol. Options related to these operations are available on the Symbol menu and the Symbol Draw menu.
