Hi Szymon,
You might do this without my package with

Show[{ListPlot3D[Data,
   PlotRange -> {{-0.3, 0.3}, {-0.3, 0.3}, {-0.1, 0.6}},
   MeshFunctions -> {#3 &}, Mesh -> {Range[-0.1, 0.6, 0.1]}],
  ListPointPlot3D[Data,
   PlotRange -> {{-0.3, 0.3}, {-0.3, 0.3}, {-0.1, 0.6}}]}]

or with my package and with definitions below (shows more detail, takes some
time)

test == Interpolation[Data1, Method -> "ObtuseAngle",
  InterpolationOrder -> 2];
Show[{Plot3D[test[{x, y}], {x, -0.3, 0.3}, {y, -0.3, 0.3},
   PlotRange -> {-0.1, 0.6}, MeshFunctions -> {#3 &},
   Mesh -> {Range[-0.1, 0.6, 0.1]}, PlotPoints -> 30],
  ListPointPlot3D[Data,
   PlotRange -> {{-0.3, 0.3}, {-0.3, 0.3}, {-0.1, 0.6}}]}]

hi there,
the interpolation works fine now,
but I wonder whether it is possible to make a contour lines on Plot3D curve=
