Abstract: An automatic modeling method for solid model of structure is proposed based on the frame model of the lashing bridge structure created by parameterized templates, in order to improve the efficiency of 3D design of lashing bridges in CATIA V6. The geometric features and parameter properties of the components of the structure frame model are analyzed and reviewed. An automatic modeling program is then developed for the lashing bridge by using the professional interfaces that are provided by the secondary development tool component application architecture（CAA） together with the out of the box functions of building solid model of the structure on the CATIA V6 platform. The feasibility and efficiency of the automatic generation technology for the structure detail model（SDM） of CATIA V6 are verified based on the 3D design of the lashing bridge for a 16 000 TEU container ship. This automatic modeling technology improves the 3D design methodology of the lashing bridge based on CATIA V6, resulting in higher modeling efficiency and accuracy than the manual modeling technology with reduced implementation cost of the 3D design, indicating that the technology has strong engineering practical value.

摘要： 为了提高CATIA V6平台中绑扎桥三维设计效率,该文基于运用参数化模板创建的绑扎桥结构骨架模型,提出了结构实体模型的自动建模方法;通过对结构骨架模型中的构件几何特征和参数属性进行分析和梳理,结合CATIA V6平台创建结构实体模型原生功能,运用二次开发语言组件应用架构（component application architecture,CAA）提供的专业接口开发了自动建模程序,以16 000标准箱大型集装箱船绑扎桥三维设计为例,验证了基于CATIA V6平台的结构实体模型（structure detail model,SDM）自动生成技术的可行性和高效性。该技术完善了基于CATIA V6平台的绑扎桥三维设计方法论,与手动创建相比,极大地提高了建模效率和模型准确性,也有效降低了三维设计方法的实施成本,具有较强的工程实用价值。
