《机械制图》准确地表达了机件(机器或零、部件)的形状和尺寸以及制造和检验该机件时所需要的技术要求。未来从事工程技术工作的学生,必须具有制图的技能和看图的本领。因此教师在教学中要充分发挥主导作用,使学生掌握这门学科。 Mechanical drawing accurately expresses the shape and size of the machine (machine or zero, part) as well as the technical requirements required to manufacture and test the machine. Students who are engaged in engineering and technical work in the future must have the skills of drawing and the ability to read pictures. Therefore, teachers should give full play to their leading role in teaching to enable students to master this discipline.
