Sets the method for defining the coordinate system.
Key-in (Relative To Another CS)
Specifies that you want to define the orientation of the new coordinate system relative to an existing coordinate system.
Geometry
Specifies that you want to define the orientation of the new coordinate system relative to geometry on the model. When you define a coordinate system relative to the model, the coordinate system is associative to the model geometry. If the model geometry changes orientation, the coordinate system also updates.
Displays the Coordinate System Options dialog box when you select the Coordinate System command.
