Since some students' spatial imagination is weak and the ability of engineering drawing is poor, this paper proposes the teaching content of "Fundamentals of Engineering Drawing" should start from three-dimensional solid modeling, and then explains the two-dimensional drawings. Students should have the ability to do three-dimensional solid modeling and generate two-dimensional engineering drawings which meet the national standard with the three-dimensional design software, which is a necessary requirement of modern design for the engineering drawing teaching, and which meanwhile conforms to the laws of human understanding. It is proposed that we should combine the three-dimensional modeling with two-dimensional engineering drawings, and make use of the flipped class teaching method and diversified test means to cultivate the students' interest in learning, enhance students' the ability of reading and drawing engineering drawings, and lay a solid foundation for subsequent courses.
