模型视图定义在结构分析模型中的研究

Research on Model View Definition in Structural Analysis Model

在建筑设计工作中,不同专业BIM软件间的模型交互障碍是影响当前BIM发展的掣肘。利用国际通用的BIM数据标准,即IFC(Industry Foundation Classes)标准,可为解决上述问题提供基础支持。在IFC标准应用过程中,IFC实体对象需要和具体信息进行绑定,因而标准化的模型视图定义(Model View Definition,MVD)被提了出来。本文介绍了MVD标准格式,包括三大构成模块Concept(概念)、Diagram(图表)和相应的Document(文档)描述,并尝试将这个标准与结构分析模型的标准化表达相结合,与IFC实体对象进行关联,对实现结构分析模型的数据共享与转换工作具有指导意义。

In the building design,the barrier of model interaction between different professional BIM software is a constraint affecting the development of BIM.The international BIM data standard,which is IFC(Industry Foundation Classes)Standard,can provide basic support for solving the above problems.During the application of IFC Standard,IFC entity objects need to be bound to specific information,so a standardized Model View Definition(MVD)is proposed.This paper expounds the standard expression format of MVD in detail,and introduces three components of MVD,which are the Concept,Diagram and corresponding Document descriptions.The author tries to combine this standard with the standardized expression of the structural analysis model,and associate it with IFC entity objects,which is instructive for the data sharing and transformation of the structural analysis model.
