Used to select a geographic coordinate system (GCS) from the predefined library supplied with MicroStation PowerDraft. This is useful when:

• Existing data was drawn in a geographic coordinate system (for example a state plane or country grid coordinate system) and you want to make MicroStation PowerDraft aware of that GCS.
• Data is correctly drawn in one specified GCS, but you want to reproject that data to a different GCS.
• You want to designate the GCS for a new design file.
