Paul,
I don't know of any existing filter to do that, but a pretty simple
programmable filter can do it. Here is the script that will achieve it. Just
create a custom filter and copy this into the script.
input = self.GetUnstructuredGridInput() output =
self.GetUnstructuredGridOutput()
output.GetPointData().PassData(input.GetPointData())
output.GetCellData().PassData(input.GetCellData()) cellTypes =
vtk.vtkUnsignedCharArray() cellTypes.DeepCopy(input.GetCellTypesArray())
cellTypes.SetName("Cell Types") output.GetCellData().AddArray(cellTypes)
If you plan to use this multiple times, you probably want to wrap this in a
custom filter.

Hello,
Does anyone know an easy way to extract all cells of a particular type from an
unstructured grid (without writing code either a plugin or python script)? I
was thinking it be possible with the calculator and the number of points in a
cell but I can't get access to that.
Thanks,
Paul
