Hello,

I’m making a **Python Programmable filter** with several vtk operations concatenated. One of this operations requires applying **CleanToGrid** to a vtk object (It can be either vtkMultiBlockDataSet or vtkUnstructuredGrid). So, **what is the vtk-equivalent for this operation?**

Thanks

Miguel

Hello,

`vtkCleanUnstructuredGrid` is what you want. `Clean To Grid` is just a label added in ParaView around this filter.
