 See http://groups.google.com/group/sage-
 support/browse_thread/thread/e05229d90733c78d for an example of how to do
 CSG (intersections and unions of solid objects) with implicit_plot3d; I
 think the given example:
 {{{
 sage: var('x,y,z')
 (x, y, z)
 sage: implicit_plot3d(max_symbolic(min_symbolic(x*x+y*y-1, x*x+z*z-2),
 x-1.8, y-1.8, z-1.8, -x-1.8, -y-1.8, -z-1.8), (x, -2, 2), (y, -2, 2), (z,
 -2, 2), smooth=False)
 }}}
 (along with some explanation) should be added to the implicit_plot3d
 docstring.
