[vtkusers] Removing cells inside solids !

[Amy Henderson]

You could try using vtkAppendFilter or vtkAppendPolyData depending on which 
type your data set is.  (vtkAppendFilter works on any type of data set and 
produces a vtkUnstructuredGrid. vtkAppendPolyData works on vtkPolyData and 
produces vtkPolyData output.)
