With the Presentations package you would simply draw the surface, then draw the point, and add any other objects you might want. Needs["Presentations`Master`"] Draw3DItems[ {Draw3D[Sin[x y], {x, -2, 2}, {y, -2, 2}], Red, AbsolutePointSize[7], Point[{0, 0, 0}]}, Axes -> True] -- David Park djmpark at comcast.net http://home.comcast.net/~djmpark/ "Kevin J.
