Combining the teaching practice and academic analysis, we explored and studied various teaching methods of "Technical Drawing" to stimulate students' interest in learning and to improve the quality of teaching. It mainly includes a good teacher-student relationship, a combination of various teaching methods, good first-lesson, intensive teaching and process evaluation. According to the characteristics of students and the teaching content, the teaching methods can be scientifically set up to achieve good teaching quality and training results. The initial application results are: use in combination with audio-visual equipment such as 3D images on a computer; perform physical models with a miniature scale from on-paper drawings and especially experience group activities during student practice hours. Through this study, at the Ho Chi Minh city University of Technology, VNU-HCM, faculty of Transportation Engineering, we have tried to find ways to alleviate the difficulties, stimulate students' interest in learning in two directions: 1) enrich the imagination of 3D space and 2) increase the introduction of the production knowledge in the most condensed way. The ultimate goal is to improve teaching efficiency in this subject. On the other hand, the products, models, created by students from the subject are also the good models for the next courses.
