《机械制图》课在当前职业院校老师和学生心目中普遍认为是比较难的一门课,该课程的困难点是学生识图、绘图技能的培养,具体体现在复杂的三维图形与为二维图形相互转化时带来的认识、空间思维活动中,难以适应的情况在很多学生中都存在。鉴于在上述的问题上,使用Pro/E三维软件的特点,构建三维模型库,以立体的、漂亮生动的表达模型和零部件,平且复杂的零件可以实现三维到二维的转换。笔者通过Pro/E软件在机械制图课中的运用,起到了良好的教学效果。 The mechanical drawing course is generally regarded as a difficult lesson in the minds of current vocational college teachers and students. The difficult point of this course is the training of student’s drawing and drawing skills, which is embodied in the complex three-dimensional graphics and the two The understanding brought about by the mutual transformation of the graphics and the difficulty of adaptation in the space thinking activities exists in many students. In view of the above issues, the use of Pro / E three-dimensional software features, the construction of three-dimensional model library to three-dimensional, beautiful and vivid expression models and components, flat and complex parts can achieve three-dimensional to two-dimensional conversion. The author through the Pro / E software in mechanical drawing lessons, played a good teaching effect.
