API Reference > geometry-core > Solid > Cone Cone Class A cone with axis along the z axis of a (possibly skewed) local coordinate system. In local coordinates, the sections at z=0 and z=1 are circles of radius r0 and r1. Either one individually may be zero, but they may not both be zero. The stored matrix has unit vectors in the xy columns, and full-length z column.
