Quick update based on another post ([https://discourse.vtk.org/t/python-seg-fault/3353](https://discourse.vtk.org/t/python-seg-fault/3353)).

If I do

```auto
my_poly.EditableOn()
my_poly.BuildLinks()
point_n = my_poly.GetNumberOfPoints()
my_poly.DeleteCell(point_n - 2) 
my_poly.DeletePoint(point_n - 1) 
my_poly.Modified()

```

I get no error, but the polydata is not modified. I tried also with Update() but it rises an error.

Thanks again!
