VTKRuledSurface Bug?

Hi, I have made a code example that shows exactly the same problem reported by the original poster using vtkRuledSurfaceFilter with PointWalk mode All the code is vtk, except I had to replace vtk.vtkFrenetSerretFrame() with slicer.vtkParallelTransportFrame() # Create profile vtk.vtkMath.RandomSeed(7859821) diskSource = vtk.vtkDiskSource() diskSource.SetCircumferentialResolution(5) clean = vtk.vtkCleanPolyData() clean.SetInputConnection(diskSource.GetOutputPort()) edges = vt…

That filter has a bug, but if you’d solve it I think it would cover your use case

Hope it helps
