how can i plot the following 2 3D-graphs into one graph so that i can see where they intersect. Plot3D[3*x^2*y , {x, 1, 2}, {y, 1, 2}]; Plot3D[3*x^2*y , {x, 1, 2}, {y, 1, 2}]; Plot3D[{3*x^2*y,3*x^2*y},{x,1,2},{y,1,2}] would be nice but doesn't work, since the second argument if for coloring the first. Is there an easy solution? thanks best juergen
