[vtkusers] vtk cutter

[Milan Augustin]

Hello,
Please advice when cut 3d model. Does not hollow part of the model. Cut -
Hollow cone - full circle. I need to see the ring, see figure 1 and 2.
part code:
   # cut mesh

   self.cutEdges = vtk.vtkCutter()

   self.cutEdges.SetInput(meshNormals.GetOutput())

   self.cutEdges.SetCutFunction(self.plane)

   self.cutEdges.GenerateCutScalarsOn()

   self.cutEdges.SetValue(0, 0.0)

   self.cutStrips = vtk.vtkStripper()

   self.cutStrips.SetInput(self.cutEdges.GetOutput())

   self.cutStrips.Update()

I attach the whole code
Thank you for any advice.
                                             Augustin
