MicroStation dimension styles allow you to save dimension settings by name. This allows for greater unity between groups of dimensions in the file, as several different styles can be used for various models or portions of a model. Dimension styles are managed through the Dimension Styles dialog.

AutoCAD DWG files also include dimension styles. When you open a DWG file in MicroStation, the default dimension styles are available. You can also import dimension styles from DWG files into DGN files.

MicroStation supports associative dimensions in DWG files from AutoCAD 2002 and later releases. Within MicroStation, you can also create, edit, and save associative dimensions to DWG files.
