SO24_EXTRA_GEOM (Auxiliary Geometry)
Y/N/E/W
GeomIntegrityCHECK reports the solid elements that are hidden from view (for example, cut-off component part areas and dead branches).
In addition, it reports added material in component part areas that are already filled with material, without altering the component part in any way (for example, addition of a ball or sphere to a rectangular solid).
GeomIntegrityCHECK also reports geometrical elements that have no logical relationship to the given solid.
