“Automotive Manufacturing Technology” course teaching, “size chain ” chapter is the teaching of the difficulties and priorities. In this paper, we analyze systematically the core teaching process of dimensional chain from the aspects of drawing dimension chain diagram, determining closed loop, increasing and decreasing ring, solving dimension chain, checking result, and so on, so that students can quickly understand and master the dimension chain Points and applications to improve their teaching effectiveness.
