The Import IGES utility imports IGES dimension entities as Bentley Raceway and Cable Management dimension elements. To override this default, you must exclude the Bentley Raceway and Cable Management dimension element. Then the Import IGES process converts IGES dimension entities into discrete Bentley Raceway and Cable Management primitive elements, such as lines and text, and creates a graphic group. This output is the same as generated with MicroStation v5.0.
