Text styles can be stored in a DGN library. A DGN library that contains text styles is also known as a "text style library," and a text style from a library is referred to as a "library text style."

The Text Styles dialog displays text styles in all text style libraries found by the MS_DGNLIBLIST_TEXTSTYLES configuration variable. You can save and then modify local copies of these text styles. Once a library style is copied locally, it is not automatically synchronized with the library style. It can, however, be manually synchronized. Text styles are matched with library text styles by name.

You should avoid storing multiple text styles with the same name across DGN libraries. If the MS_DGNLIBLIST_TEXTSTYLES configuration variable results in having multiple library text styles by the same name, the text style in the DGN library that is processed first appears in the Text Styles dialog.
