摘　　要：阐述了焊接结构件ＣＡＤ系统的基于特征的建模技术。根据焊接结构件的特征分类，运用特征建模原理，建立焊接结构件的组元特征库，并生成由形状特征模型、管理特征模型、精度特征模型、焊接特征模型和材料特征模型组成的产品模型。产品模型面向对象，存贮信息完整、清晰、简单，不仅为焊接结构件ＣＡＤ系统的研制，也为ＣＡＤ／ＣＡＰＰ／ＣＡＭ的集成奠定了基础。This paper presents a feature technique for CADSWS(Computer Aided Design System for Welded Structures).On the basis of analyzing the feature of welded structures, the feature libraries and product model of welded structures have been deve loped.The product model of welded structures consists of shape feature model,management feature model,precision feature model,welding feature model and material feature model.The simple and reliable model is object oriented. It is the base of constructing the CAD system and the integration of CAD/CAPP/CAM.
