[Jack001]

My problem is as follows. The script below basically orders unstructured points of an airfoil profile so that I get points ordered from the Leading edge to trailing edge on both suction and pressure surfaces. This is accomplished inside the Programmable filter. The point of interest is

point_coord

. I now want to use the result of this variable in a plot over line filter. How can I "communicate" this variable from inside the programmable filter to the input of the plot over line filter like below:

#### import the simple module from the paraview
from paraview.simple import *






# create a new 'EnSight Reader'
cFX_00 = EnSightReader(CaseFileName='/Users/CFD/Rotor/user_files/CFX_001_ensight.case')


# create a new 'Extract Block'
extractBlock1 = ExtractBlock(Input=cFX_00)

# Properties modified on extractBlock1
extractBlock1.BlockIndices = [4]

# create a new 'Extract Surface'
extractSurface1 = ExtractSurface(Input=extractBlock1)

# create a new 'Generate Surface Normals'
generateSurfaceNormals1 = GenerateSurfaceNormals(Input=extractSurface1)
generateSurfaceNormals1.FlipNormals = 0

# create a new 'Programmable Filter'
programmableFilter1 = ProgrammableFilter(Input=generateSurfaceNormals1)
