That is not directly possible but this approach should work:

> It is possible to slice and clip a volume with a surface by using a Phyton Programmable Filter. This relies on the [vtkImplicitPolyDataDistance](https://vtk.org/doc/nightly/html/classvtkImplicitPolyDataDistance.html#details), so the result is an approximation, not an actual boolean operation. Steps for clip: Open a volume, apply Open a surface, apply In the pipeline browser, click on the volume, then press Ctrl, then click on the surface Add a Programmable Filter Set the output type to vtkUnstructuredGrid Set the script to import paraview.modules.vtkPVVTKExtensionsFilte…
