<div dir="ltr">Hi,<div><br></div><div>I'm trying to use the extract cells filter on an unstructured grid with polyhedra cells but it is crashing. I'm not totally sure if the problem is in vtkUnstructuredGrid or vtkExtractCells. When the vtkUnstructuredGrid::SetCells is called the cellArray seems to be IDs that are (cell1_numpts, cell1_pt1, cell1_pt2, cell1_ptX, cell2_numpts, cell2_pt1, ...) when I thought it should be using faces for polyhedra. I've attached a simple dataset and python script to reproduce the issue.</div>
<div><br></div><div>Does anyone have the time to take a look? Or, can anyone suggest another filter than might work for me?</div><div><br></div><div>Thanks in advance,</div><div>Paul</div></div>
