Code | Notes | Examples |
---|---|---|
GD | Multiple mirror planes pass through a fixed axis with one mirror plane perpendicular to the axis (dihedral symmetry) | Hourglasses, prisms, cylinders, spheres |
GC | Multiple mirror planes pass through a fixed axis (cyclic symmetry) | Cones, tables |
GR | Five platonic solids (rotational symmetry) | tetrahedron, cube, octahedron, dodecahedron, and icosahedron |
GU | Only one plane reflection exists (unique symmetry). Usually found in human-man objects | Airplanes, animals, A- or T-posed manikin full body with 1:10 scale or more |
GZ | No plane reflection symmetry exists (zero symmetry) | Plants, trees, asymmetrically posed manikins with 1:10 scale or more |
