[vtkusers] Read data from a vtkCutter

[Hsiang-Chi Kuo]

Hi Bill,

I have tested the example. It turned out:
-----------Lines without using vtkStripper
There are 0 lines in the polydata
-----------Lines using vtkStripper
There are 0 lines in the polydata

No line and no polydata output from the program. Can you advise what's
wrong?

Thanks,

Howard

This example accesses the lines after cutting and stripping:
