/Column describes a solid cylinder.
Its height extends along the z axis.
The top circle is on plane z = +dz,
and the bottom circle on plane z = -dz.
Centers of the top and bottom circles are
(0, 0, +dz) and (0, 0, -dz), respectively.
/Column is equivalent to /Tubs
with full azimuthal angle () and zero minimum radius.
