摘　　要：基于模型的数字化定义技术以三维产品模型为基础,集成了三维空间尺寸公差标注和制造要求标注在内的特征信息,在脱离了二维工程图纸应用的情况下,实现对产品特征描述、共享,满足信息系统的直接传递要求,并实现对产品信息的分类管理。结合我国787飞机转包生产,分析了基于模型的定义技术的应用情况。The model based digital definition technolgy integrates feature information including 3D size tolerance annotation and manufacturing requirement annotation on the basis of 3D product model. Without 2D drawings, the model based definition can realize the description and sharing of product features, meet the re- quirement for direct transfer of information system, and manage information by classification. The application status of model based definition technology is analyzed according to the subcontract production of B787 aircraft in China.
