机械制图是中等专业学校机械类或近机械类专业学生必须学习的一门专业基础课,是后续各门专业课学习的基础。课程的重点是培养学生识图、绘图能力,培养学生物图转换能力,即能够将空间立体转化为平面图形(绘图过程),同时又能够将平面图形转化为空间立体(识图过程)。 Mechanical drawing is a professional basic course that must be studied by mechanical major or mechanical major students in secondary vocational schools and is the basis of follow-up specialized courses. The focus of the course is to cultivate students ’ability of drawing and drawing, and to cultivate the ability of students’ drawing transformation, that is, to transform the spatial three-dimensional into the plane graphic (drawing process) while transforming the plane graphic into the spatial three-dimensional (knowledge drawing process).
