Get intersection of PolyData line and a plane

Support

Sorry for the long delay, here’s approximately the code I was using:

vplane = vtk.vtkPlane()
vplane.SetOrigin((-0.4, 0, 0))
vplane.SetNormal((1,0,0))

cutter = vtk.vtkCutter()
cutter.SetCutFunction(vplane)
cutter.SetInputData(walledgePolySample)
cutter.Update()
cutterout = cutter.GetOutputDataObject(0) 

type(cutterout) # vtkCommonDataModelPython.vtkPolyData
cutterout.GetNumberOfVerts() # 0

Note that the walledgePolySample is a line planar in XY and goes from x={-0.54, -0.31}, y={0,0}.
