《机械制图》是各层次工科类大学机械类专业和近机械类专业必修的、高度实践性的一门技术基础课。目前流行的几种三维CAD软件,可以满足包括三维造型与三维设计、计算机辅助工程分析、机构运动分析与仿真、装配干涉检验、三维转二维、图样档案管理等各种应用需要。随着先进的三维设计、制造手段和技术应用的不断发展,相应的《机械制图》课程的各个知识结构部分的教学方法、教学手段等方面的改革势在必行。 “Mechanical drawing” is a compulsory and highly practical basic course for mechanics and mechanical engineering at all levels of engineering universities. At present, several popular 3D CAD softwares can meet various application needs including three-dimensional modeling and three-dimensional design, computer aided engineering analysis, mechanism movement analysis and simulation, assembly interference inspection, three-dimensional transformation two-dimensional and drawing file management. With the continuous development of advanced 3D design and manufacturing methods and application of technology, the reform of teaching methods and teaching methods of various knowledge structure parts of corresponding “mechanical drawing” courses is imperative.
