Ok, it appears the code I posted works if I don't call pe->Delete(). I was hoping the DeepCopy would allow me to then free up this memory. Maybe someone could clear this up for me?

I pass in a vtkPolyData object and receive a vtkMultiBlockDataSet object as output. My output data object is also of type vtkMultiBlockDataSet, so I'm trying to perform a DeepCopy of the temp object, but I'm receiving a segmentation fault. Can someone point out what I'm missing here? { vtkMultiBlockDataSet *output = vtkMultiBlockDataSet::SafeDownCast( outInfo->Get(vtkDataObject::DATA_OBJECT()) ); //polydata is a pointer to a populated vtkPolyData object. std::cout << "Executing vtkPlotEdges..." << std::endl; vtkPlotEdges* pe = vtkPlotEdges::New(); pe->SetInput(outputPoly); pe->Update(); output->DeepCopy(pe->GetOutput()); pe->Delete(); } Cheers, Adriano =================================== Adriano Gagliardi MEng PhD Project Scientist Computational Aerodynamics Aircraft Research Association Ltd.
