Engineering Graphic Transition in Third-Angle and First-Angle Projection
This paper focuses on the transition methods and skills of engineering graphic in third-angle projection and first-angle projection. According to the Chinese National Standard of Technical Drawings, the first-angle projection is used to make engineering drawings while in some other countries, such as in the USA and Canada, the third-angle projection is used. The transition methods are widely applied to the engineering graphics field in the world.
