Auxiliary view method
Learning outcomes of this video Use the principles of an auxiliary view to find turning points and intersection points on line of intersection between two surfaces Applying the principle of producing straight line elements from a pyramid in order to locate a point on a surface. Show how inclined cutting planes method results in the same solution as auxiliary view method
