Hi, we settled the matter privately. Here is a possible solution: Hi Nodar, StackGraphics will stack any 2 dimensional , not only curves. Here is an example: << Graphics`FilledPlot` <<Graphics`Graphics3D` g1 = FilledPlot[{Sin[x], Cos[x]}, {x, Pi/4, (5/4)*Pi}] Show[StackGraphics[{g1, g1, g1, g1}]] note that sometimes ther are small errors visible.
