摘　　要：针对目前船用柴油机零件设计制造中存在着二维图纸信息表达困难,信息传递不通畅等问题,提出使用集成的全三维数模进行信息传递的方法。采用全三维标注表达法表达设计意图,在工艺设计阶段依据这些设计意图规划工艺路线。以NX系统为软件平台,研究了基于全三维模型的信息提取方法,满足了后续应用模块的需要,实现了基于船用柴油机零件三维数字化模型设计与制造的集成化和自动化。Integrated method of presenting and conveying information based on 3D digital definition is proposed for design and manufacturing of marine diesel components in order that a practical means is provided for addressing the inconvenience of information presentation and obstruction of message delivery in current combination way of 3D modeling and 2D drawings. Annotations are attached to express the design intent, such as geometrical dimension and tolerance. During process of design, such information is employed to plan the routine. With the NX software platform, model based information extraction is investigated and secondary development is implemented to offer ways of information application usage. At last, the integrated 3D digital definition and application of marine diesel engine part are realized.
