Set Geographic Coordinate System In References Dialog

Used to set the geospatial coordinate systems (GCS) of attached references based on the GCS of the active model. If the GCS is selected from the standard library, it can be used to set the GCS for coincident, unscaled, and unrotated reference attachments. If the GCS is calculated from placemark monuments, it can be used to set the GCS for unscaled references.
