Redefine Symbols

If you have created and used a symbol in your document, you can easily change all instances by redefining the symbol. Place an instance of your symbol from the Symbols palette and use the Object>Expand command to edit the original artwork. Make the changes to the artwork and keep it selected. In the Symbols palette, click once on the original symbol, and from the palette's flyout menu, choose Redefine Symbol. All instances will automatically change to the edited symbol.
