摘　　要：本文研究了在车身内外覆盖件及其模具设计制造过程中遇到的由二维产品图纸建立三维CAD模型的问题，提出了应用矢量化和三维造型技术，实现由二维产品图建立三维CAD模型的原型系统，利用该系统，完成了若干实际工作。实践表明，本文提出的方法和原型系统对于解决由二维模型建造三维模型问题是非常有效的。A prototype system is presented to complete the construction of 3D CAD model from 2D product drawing byvectorizing technique in this paper. The engineers always get confused with the problem of constructing 3D CAD model from2D product drawing in the designing and manufacturing process of the outer & inner autobody panel and its die. Somepractical works have been done by the provided system. According to the practice results, the presented method andprototype system is effective to process the' 2D to 3D' problem.
