In this paper two nomographs are presented to help the evaluation of facet cutting angles^<2)>, about whlch mathematical expressions were reported In a series of the author's paper in this Jonrnal^<1)>. Using these nomographs and a piece of tracing on which a straight line is drawn , it is possible to evaluate the facet cutting angles, graphically, and complicated mathematic calculation is no more necessary.
