| 摘 要： | 针对创新设计中零部件的三维虚拟造型问题，提出了一种由二维投影图生成三维立体图的计算机化辨识方法。通过辨识简单三维立体的形状和空间位置，克服了二维图形中面的积聚性和零件之间不规则相贯和截交曲线的识别问题，进而实现了复杂组合形体的计算机化设计与造型。最后，以箱体类零件为例，在AutoCAD环境下利用VC 和ObiectARX开发工具编程验证了该方法的有效性。

| Abstract: | Aimed at the three dimensional virtual modeling of part in the creative design, an identified method for constructing solid geometry from 3 view orthographic figures is put forward. By the recognition of shape and space position of the simple solid entity, the accumulation of the plane and the irregular curve of intersection are overcome. Moreover the computerized design and modeling of complex compound entity are realized. Finally, with the programming tools of VC++ and ObjectARX in the AutoCAD environment, the box part is used as an example to test the validity of this method. |
