Hello Tiago, Using Fetch you should end up with a vtkPolyData object which have accessors to triangle point ids (using GetPolys() then a traversal on the vtkCellArray or directly using GetCellPoints(). Point coordinates can be retrieved using GetPoint() function. So could you be more specific on how you call servermanager.Fetch() and what you are doing next to retrieve your normals?
