Hi Evgeniya,

Try renaming your class to vtkMyClass to see if that works.

Wrapping was done with a similar to http://public.kitware.com/pipermail/vtkusers/2016-August/096019.html <http://public.kitware.com/pipermail/vtkusers/2016-August/096019.html>  CMakeLists.txt .All methods are accessed and work fine within python. But when I try to pass this class variable to vtkSampleFunction as ImplicitFunction, I receive an error:>m=myClassPython.myClass()>s=vtk.vtkSampleFunction()>s.SetImplicitFunction(m)*
