Its really strange but you seem to have missed the most obvious and very noticeable thing: the completelynew graphic engine. Jus tto illustrate it: 1. Make simple plot: Plot[Sin[x], {x, -2 Pi, 2 Pi}] Click on the graphic to select it. Now doble click on the graph of of the function. You can then drag the grtaph around with the mouse. triple click on the graph. You will see individual points that you can now edit to change the shape of the curve. Look under the Graphics menu. You will find a set of drawing tools that you can use to edit the graphic further. 2. Try this: ContourPlot3D[((Sqrt[x^2 + y^2] - 1)^2 + z^2 - 0.2) ((Sqrt[(x - 2.5)^2 + (y - 2.5)^2] - 1)^2 + z^2 - 0.2) ((Sqrt[(x - 5)^2 + (y - 5)^2] - 1)^2 + z^2 - 0.2) ((Sqrt[(x + 2.5)^2 + (y + 2.5)^2] - 1)^2 + z^2 - 0.2) ((Sqrt[(x + 5)^2 + (y + 5)^2] - 1)^2 + z^2 - 0.2), {x, -7, 7}, {y, -7, 7}, {z, -2, 2}, Contours -> {0}, Mesh -> None, Axes -> False, ContourStyle -> Green, Boxed -> False] This may take a bit of time, depending onthe speed of yoru computer but... try doing this with any previous version of Matheamtica (without the help of Jens Kuska's MathGl3D) Not to mention the fact that you can now rotate this thing in real time. And that's just a few of the most obvous (to me) new things. It seems to me you have missed the "raison d'etre" of Mathematica 6.0 Andrzej Kozlowski On 20 May 2007, at 15:40, science2003 at libero.it wrote: > Premise: I use Mathematica. here and then -not everyday.
