If you have added or edited line styles in either the catalog line styles library or project-specific line styles library, you can save the custom line styles to the external line styles library file (linestyles.klb). You can then import the customized line styles from the library file into any line styles library, whether that be the catalog line styles library or project-specific line styles library. The library file basically acts like a shuttle between libraries.
You can save line styles to the default line styles library, or create a new library to save them in.
To save customized line styles to the line styles library file:
Access the line styles library. How to
In the Line Styles dialog, select File > Transfer.
In the Open dialog, select the linestyles.klb file (or whatever file you want to save to), then click Open.
Tip: You can create a new library file if you want by entering a name in the File name edit box.
In the left pane of the Transfer dialog, select the line style you want to save, then click Export Item. To export the entire list, just click Export All. The library file is updated.
Click OK.
