Editing an Existing Symbol

When a symbol is used in a project, it is copied to the project from a global library. Any changes made to the symbol are made to the project's copy of the symbol and only affect the symbol in the project and not in any other project. To edit an existing symbol, either:

• From the Project Manager window, open the project that contains the symbol you want and open Definitions > Symbols. Either double-click the symbol you want to edit or right-click the symbol and select Edit Symbol.
• Open Tools > Edit Libraries > Symbols. From the Symbols tab of the Edit Libraries window, either double-click the symbol that you want to edit or right-click the symbol and choose Edit Symbol.

The symbol editor opens with the selected symbol ready for editing.

Use the symbol editor to:

• Draw graphical primitives, such as rectangles, circles, and arcs, using options on the Draw menu.
• Add pins for electrical connections using the Pin option on the Draw menu.
• Modify pin properties in the Pin List dialog box.
• Add labels. To include component properties or other variables in a label, use the Property Display Setup option on the Symbol menu. For unchanging text, use the text option on the Draw menu. Unusual labels are most likely represent a component property.
• Update the current project with the new or revised symbol definition using the Update Project option on the Symbol menu

You can also export a symbol to a symbol library (.aslb) file for use in other projects. For information on how to do this, see the Edit Libraries.
