If you initiate a symbol library update in the Synchronization of master data dialog (menu items Utilities > Master data > Synchronize current project), the individual symbols will be checked before the symbol library is replaced.
Symbol libraries contained in the Assignment 'Property / value to graphic', Assignment 'Function definition to graphic' and Assignment 'Index to graphic' form properties.
All symbol libraries opened via Utilities > Master data > Symbol library > Open or generated via Utilities > Master data > Symbol library > New.
All symbol libraries specified under Options > Settings > Projects > "Project name" > Management > Symbol libraries.
Symbol libraries are referenced as follows: The new symbol libraries are stored in the project.
Proceed this way for all of the further symbol libraries that you would like to store in the project.
If necessary, change the preceding sign (the default is the first letter of the symbol library) so that you can differentiate between the symbol libraries in the list view in the Symbol selection if you select Popup menu > Name with preceding sign.
Select the Synchronize check box if the symbol library should be managed on a project basis.
If you have clicked in an empty column, the storage process is automatically started.
If the two symbol libraries are compatible, you have to confirm the exchange in the Exchange symbol libraries dialog. If this is not the case, the process will be interrupted with a prompt.
If you have clicked in the column of an already assigned symbol library, EPLAN checks whether the original symbol library and the newly selected one are both compatible.
In the Select symbol library dialog select the new symbol library.
In the Settings: Symbol libraries dialog, click in a column below Symbol libraries.
Symbol libraries are added to the project as soon as they are entered into the project settings, or they are opened or generated in the project. Store symbol libraries (copy to the project) Symbol selection ( Insert > Symbol) only displays those symbols from the stored symbol libraries and symbol libraries are identified by name (without the path) in projects. When you try to open such a symbol library, a message will appear and the action is canceled. Some symbol libraries such as SPECIAL.slk are blocked and can't be edited by you.
