Use RegionFunction Manipulate[ParametricPlot3D[ {Cos[u], Sin[u] + Cos[v], Sin[v]}, {u, 0, umax}, {v, -Pi, vmax}, RegionFunction -> Function[{x, y, z}, x < xmax && y > ymin && z < zmax], PlotRange -> {{-1, 1}, {-2, 2}, {-1, 1}}], {{umax, 2 Pi}, 0.01, 2 Pi, 0.01, Appearance -> "Labeled"}, {{vmax, 2 Pi}, -Pi + 0.01, Pi, 0.01, Appearance -> "Labeled"}, {{xmax, 1}, -1, 1, 0.02, Appearance -> "Labeled"}, {{ymin, -2}, -2, 2, 0.04, Appearance -> "Labeled"}, {{zmax, 1}, -1, 1, 0.02, Appearance -> "Labeled"}, ControlType -> {Slider, VerticalSlider, Slider, Slider, VerticalSlider}, ControlPlacement -> {Top, Right, Top, Bottom, Right}] Bob Hanlon ---- VICTOR <victor.herasme at gmail.com> wrote: ============= Hi, i have to analyze a huge amount of data. In this page: http://www.wolfram.com/products/mathematica/newin6/content/DynamicInteractivity/UseAllStandardFormsOfControls.html i found an example that would be very useful to my work. Does anyone have any idea on how to create this ? Specifically what i need is the plane that cuts the graphic and shows the values at a specific position, i.e. a plane parallel to the XY that i can place at any position of the Z axis. Any suggestions appreciated. Thanks, Victor
