在中等职业技术学校中,机械识图是机械类专业学生必须掌握的一门实践性较强的专业基础课,但是该课程普遍存在着教师难教、学生难学的问题。将CAXA实体设计与机械识图这两门课结合起来,以机械识图教学的难点为突破口,利用CAXA软件的三维造型功能,建立三维实体模型,展示零部件立体结构,将信息化手段融入课堂,提高课堂效率和学生学习的有效性。 In secondary vocational and technical schools, mechanical drawing is a practical and basic course for students majoring in mechanical engineering. However, there is a common problem in this course that teachers are hard to teach and students are hard to learn. Combining CAXA entity design and mechanical image recognition, this dissertation takes the difficulty of mechanical figure teaching as a breakthrough point, uses the three-dimensional modeling function of CAXA software to build a three-dimensional solid model, displays the three-dimensional structure of parts and components and integrates the information technology into the classroom Improve classroom effectiveness and student learning effectiveness.
