    The Subdivision Surface modifier.
 
 Catmull-Clark
-   The default option, subdivides and smooths the surfaces.
+   Subdivides and smooths the surfaces to create a more pleasant looking mesh.
    According to its `Wikipedia page <https://en.wikipedia.org/wiki/Catmull%E2%80%93Clark_subdivision_surface>`__,
    the "arbitrary-looking formula was chosen by Catmull and Clark based on the aesthetic appearance of
    the resulting surfaces rather than on a mathematical derivation."
 Simple
-   Only subdivides the surfaces, without any smoothing
+   Only subdivides the surfaces, this often does not provide any smoothing
+   unless the surface is :term:`non-coplanar <Coplanar>`
    (the same as the :ref:`Subdivide <bpy.ops.mesh.subdivide>` operator, in Edit Mode).
-   Can be used, for example, to increase base mesh resolution when using displacement maps.
+   To work around this behavior for non-coplanar geometry,
+   :doc:`triangulate </modeling/modifiers/generate/triangulate>` to ensure all geometry is coplanar.
+   
+   Simple mode can be used, for example, to increase the base mesh resolution when using displacement maps.
