The planetary nebula known as the Cat's Eye Nebula (NGC 6543) has a complex,point-symmetric morphology that cannot be fully explained by the current theoryof planetary nebula formation, the Interacting Stellar Winds Model. In order toreveal the three dimensional (3D) structure of the Cat's Eye Nebula, we createda detailed 3D morpho-kinematic model of this nebula using a [NII] image fromthe Hubble Space Telescope and five different position-velocity diagrams usingthe SHAPE code. This modeling approach has revealed point-symmetric partialrings, which were likely formed by a precessing jet.
