Tobias, I would be helpful if you gave an explicit example of the kind of graphic you wanted. I assume that you want to combine the contour plot with other objects or surfaces. You can get a kind of contour plot by using ParametricPlot3D and using the ColorFunction and MeshFunctions options. The Presentations package gives a much more natural method for combining various objects in 2D and 3D Graphics. It has a RaiseTo3D command that will raise 2D graphics items to a 3D surface. So you can use ContourDraw (which is similar to ContourPlot) and then raise it to some surface, including of course the xy-plane. In the case of a Monge patch, where the surface is given by {x, y, f[x, y]}, the routine will automatically calculate the vertex normals so you obtain nice shading in the 3D object. You even get the tooltips on the contours. This can be easily combined with other object just by drawing one thing after another.

I tried with inset, but it doesn't work because there's an error message: "Inset is not a Graphics3D primitive or directive." Thanks for help. Cheers Tobias
