摘　　要：传统的商用软件二次开发模式难以满足钣金设计的灵活性和交互性要求,基于造型内核开发三维设计环境是可行的方案。在分析OpenCASCADE三维造型内核的开发模式和数据结构的基础上,将钣金展开方法与OpenCASCADE相结合,使用VC++开发出三维钣金设计系统。针对常用钣金件展开方法建立了数学模型,以模型数据和算法为基础,调用OpenCASCADE造型函数,实现了底层数据与显示模块的融合。无论在设计灵活性还是系统扩展性方面都优于传统的商用软件二次开发模式。The traditional second development method in commercial software can not meet the flexibility and interactivity requirements of sheet metal design.It is a more feasible way to construct 3D design environment based on modeling kernel.After analyzing the developing model and data structure of OpenCASCADE kernel,the sheet metal unfolding method is combined with OpenCASCADE system to build the 3D sheet metal design system using VC＋＋ tools.The mathematical unfolding models of traditional sheet metal are constructed.Based on the model data and algorithm,the display modules are integrated with the underlying data by calling the OpenCASCADE modeling functions.This method improves the flexibility and scalability of sheet metal design,which are insufficient with the traditional second development mode.
