Abstract: Engineering drawing is a necessary part of the graduation design of mechanical majors. It is the most intuitive graphic language for students to express their designs. Aiming at the problems of poor standardization and engineering in students' drawing, this paper puts forward three aspects of improvement: teaching system design, graduation design strengthening and teacher construction. Continuous training of drawing and standardization of drawing ability are adopted to in the teaching system. In the process of graduation design through special lectures and guidance of enterprise experts are used to improve and strengthen students' drawing ability. Training young teachers to improve their own engineering ability so as to improve their guidance level of students. Drawing ability of the students in the graduation design has been effectively improved through the implementation of the above measures.
