计算时代工程图学之定位与建设思考

Reflections on the orientation and development of engineering graphics in the era of computing

在2次《图学学科发展报告》基础上,专门讨论工程图学科学与学科的继承问题,探讨其在计算时代的定位与发展。梳理工程图学及画法几何的理论、方法和技术,揭示工程图学无歧义表达、完成工程计算中所隐含的严密理论及科学价值。剖析在计算时代工程图学呈现和渗透到计算机图形学的某些新形态。分析这2大图学分支的共性,特别是两者在图形思维和计算思维上对CAD的支撑作用。以此共性基础为核心,以工程应用为导向,以科学研究与人才培养为目标,探索建立多元思维融合的工程图学学科建设框架。

On the basis of the two development reports on graphics, the inheritance of the science and discipline of engineering graphics was particularly discussed, and its orientation and development in the computing era were also explored. The theories, methods, and technologies of engineering graphics, as well as descriptive geometry, were reviewed, revealing the rigorous theories and scientific values implied in its unambiguous expression and engineering computing. In the computing era, discussions were conducted on some new forms that have found their way from engineering graphics to computer graphics. The commonalities of these two major branches of graphics were analyzed,especially their supporting role for CAD regarding graphic thinking and computational thinking. With these common foundations as the core, the engineering application as the guide, and scientific research and talent training as the goal,explorations were pursued on the establishment of a disciplinary development framework for engineering graphics integrating with multiple thinking modes.
