[Paraview] Project polygon onto surface

[postgurke at web.de]

Adam,

Have you actually tried the filter? Because I think the output is exactly what
you're asking for: the "section" of the surface is the part of the surface where
the polyline is proceted onto it, hence a polyline with the regarding topography
values for the respective z coordinates.

Cheers
Venke
