  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 theory
of planetary nebula formation, the Interacting Stellar Winds Model. In order to
reveal the three dimensional (3D) structure of the Cat's Eye Nebula, we created
a detailed 3D morpho-kinematic model of this nebula using a [NII] image from
the Hubble Space Telescope and five different position-velocity diagrams using
the SHAPE code. This modeling approach has revealed point-symmetric partial
rings, which were likely formed by a precessing jet.
