The 3D configuration idea has been introduced into the teaching practice of engineering drawing as a feasible way to cultivate the ability of spatial imagination on account of the shortcomings of the students' scarce capacity of spatial imagination.Two-dimensional sketch is generated for three-dimensional constructional named 3D configuration and it becomes communication media of the mechanical parts design in engineering drawing.3D configuration has important significance to help students strengthen the thinking of space form and culture the good qualities of students plot.The results of practice demonstrated that the 3D configuration base on the SolidWorks software have reduced the difficulty of learning, enrich the learning content.It realizes the cultivation of spatial imagination ability and practice ability about engineering drawing, and effectively promotes the scientific development of the construction and reform of engineering drawing teaching via the summary of the teaching content and innovation of teaching method and means combined with drawing practice with AutoCAD software.%针对工程制图教学中学生空间想象能力不足的缺点,将三维构形思想作为培养空间想象能力的可行路径引入到工程制图的教学实践中.三维构形思想是基于二维草图生成三维空间形体,其逐渐成为工程制图机件设计中交流的媒介,对于辅助学生强化空间形体思维,培养学生良好的图学思维品质,具有重要意义.实践结果表明:基于SolidWorks软件的三维构形思想,降低了学习难度,丰富了学习内容,通过教学内容的总结、教学方法与手段的创新与结合AutoCAD软件的绘图实践,实现了工程制图空间想象能力与实践能力的培养,有效地促进了工程制图教学改革和建设的科学发展.
