在计算机支撑的产品信息可视化背景下,使得按照机械产品的设计和创新规律,以三维实体造型功能为平台,实现三维真实感建模表达设计、制造一体化过程成为可能,并给工程图学教育提出了新的课题。本文介绍了立足于产品三维实体几何、拓扑和工程信息的计算机描述的机械制图教学改革与探索。 Under the background of computer-supported product information visualization, it is possible to design, manufacture and integrate the three-dimensional realistic modeling and design according to the rules of mechanical product design and innovation and the three-dimensional solid modeling function Proposed a new topic. This article introduces the computer graphics teaching reform and exploration based on computer 3D geometry, topology and engineering information.
