由二维视图复原三维立体的新方法

摘要

根据工程图学和三维CAD课程的教学实践,研究、总结出一种将三维CAD中立体的构型原理、方法和成型过程用于二维视图阅读的新方法.该方法将传统的二维读图方法与现代三维CAD有关内容融合到一起.按此方法读图,不仅可以使学生根据二维视图快速复原立体空间形状,而且可以了解立体的成型方法和最佳构型过程,为三维CAD构型设计奠定基础.%Based on teaching practice in the courses of Engineering Graphics and 3D CAD, a new method integrating traditional 2D drawing with modern 3D modeling is proposed, which uses 3D CAD modeling principle, method and modeling processing in the understanding of 2D view. The method is superior for students to rapidly recover the solid special object shape from 2D view, and to understand the optimal solid modeling and processing. It lays foundation for 3D CAD modeling design.
