MicroStation Text Styles are used to define annotation symbology for all Comms features when extracted in a spatial session or when in a DGN persistent project. Once text styles are defined in the project DGNLIB, they can be imported into the project DGN seed file and will be used when the features are extracted. When changes are made in the project’s TextStyles.dgnlib file, they will be reflected in the project DGN seed file.
