Hi,<br>vtkSplineFilter will resample only the PolyLine cell present in the input. To be more precise, you should have one cell with several points in input (necessary but not sufficient). IMHO, cutter will produces one cell per edge, ie you will have N cells for N points. Then spline filter interpolate each edge, that are inherently aligned so the output points of spline filter will be on the input edges.<br>
<br>However, I didn't understand this:<br> "But only i get the initial section with tubes."<br><br>what is your problem exactly?<br><br>Jerome<br><br>
