  1. Orthographic Projection of Object Features

  2. OBJECT FEATURES are lines that represent the boundarybetween two faces. Edges Represent the intersection of two ormore edges. Corners Edge Edge No edge Corner No corner No corner

  3. Surface Surface Surface OBJECT FEATURES are areas that are bounded by edges or limiting element. Surfaces is a line that represents the last visible part of the curve surface. Limitingelement Limit Limit
