I have a PolyLine and I’d like to get the data from that line that intersects a plane. How would I do that in Python.

I’ve tried using vtkClipPolyData and vtkCutter to no avail; the output is empty.

I’m also working in Python for this and the PolyData is wrapped in pyvista’s PolyData object type.
