This DF describes a radial shape. The circular sector or cone is constructed by sweeping      

This DF describes a radial shape. The circular or spherical sector is constructed by sweeping      

 the provided range about the reference position specified outside of the context of this DF or 

 about the optional shapeReferencePoint. The range is swept between a horizontal start and a 

 horizontal end angle in the X-Y plane of a cartesian coordinate system specified outside of the
