I have come across some cases where the stripper doesn't produce continuous polylines from input line segments which are continuous - it happens when the line is not closed, and a start segment is chosen from the middle of the polyline, produces a continuous polyline to the end (i.e. no more neigbors), then produces other parts of the polyline as it encounters them in the loop - so what should be a single continuous polyline typically ends up being multiple polylines. I have a fix for this but haven't had time to check it in yet. SplineFilter will subdivide the polylines independently.<br>

Look at this example:<br><a rel="nofollow" target="_blank" href="http://vtk.org/Wiki/VTK/Examples/ExtractPolyLinesFromPolyData">http://vtk.org/Wiki/VTK/Examples/ExtractPolyLinesFromPolyData</a><br><br>it shows how to connect the segments produced by the cutter into polylines.<br>
