+    ----------

+        String of filepath to read. 
+
+    Returns

+    ----------
+    mesh : vtk.vtkPolyData
+        PolyData of surface mesh to be saved to disk. 
+    filepath : str
+        Location &amp; filename to save mesh to. 
+    scalar_name : str, optional
+        A name to assign to the active scalars of the surface mesh before saving it, by default None
+        meaning that no name will be applied.
+    points_dtype : type, optional
+        Specifies the datatype that the points should be. 
+        If they are the wrong datatype then they are changed to the requisite
+        type before savinge (writing) the file. 
+    write_binary : bool, optional
+        Specify if the save file should be binary (True) or ASCII (False). Default is False (so it will save in Binary).

+    
+    Notes
+    ----------
