# Coordinate System Representation Item

An axis system.

An `A3DRiCoordinateSystem`is an `A3DRiRepresentationItem`that specifies a coordinate system. The `A3DRiCoordinateSystemData`structure contains an `A3DMiscCartesianTransformation`axis system. This axis system owns the geometric data: there is no particular geometry attached, and the user is responsible for representation.

> An `A3DRiCoordinateSystem`is an `A3DRiRepresentationItem`and not an `A3DMiscCartesianTransformation`. Being a representation item, a coordinate system can own a local coordinate system (on the RI level), which can also own a local coordinate system, and so on…

Returns

> `A3D_SUCCESS`on success, or an error code on failure
