基于参数化造型设计及表达的工程制图国际化教学实践

论文介绍了北京理工大学机械工程专业国际化班工程制图课程的教学设计 和实践。在教学设计和实践中，面向课程目标，引入参数化造型设计所具有的参数化、变量 化、几何约束等概念及设计理念；压缩画法几何及视图基础知识，加强以三维造型软件为工 具的设计及表达能力培养；引入基于装配的零件设计理念，使学生快速掌握凑配设计技术； 全英文教学，使用一套标准打通课程，同时通过对比分析加深学生对国标的理解。学生经过 本门课程的学习，在造型设计和工程图表达等专业基础方面，达到或接近传统教学计划经过 课程设计训练才具备的水平，并具备一定的国际交流专业基础。

International Teaching Practice of Engineering Drawing Based onParametric Modeling Design and Representation

In the engineering drawing teaching practice of international program for mechanical engineering major, the concept of parametric, variational and constraint design, which are typical in modeling design, is introduced, and the fundamentals of geometric drawing and view projection are simplified while the ability of design and representation with 3d modeling software is emphasized. With modeling design in assembly environment, assembly design and parts modifying become easier than before. All lectures are given in English with ISO standard during the whole course. Chinese standard (GB) is introduced for contrast when it is different with ISO. With the training of this course, learners will possess the fundamental ability of international communication in mechanical engineering and obtain the skills of design and representation which are the object of later course training in traditional program.
