BIM模型信息分类编码分析

Analysis on BIM Model Information Classification and Coding

BIM信息编码的重点不在于代码本身,而在于分类,因为不同角色对BIM模型信息的分类方式决定了信息编码所采用的格式。基于此,文章首先介绍树状分类法、面分类法和混合分类法三种信息分类的方式,然后提出层次码、组合码和复合码三种编码方式,最后通过案例说明如何实现多个软件之间的数据传递,并将自定义分类编码附加在Revit的对象属性,从而向项目参建单位提供同一套分类编码,指导其开展协同工作,保障信息的有效传递。

The key point of BIM information coding is not the code itself,but the classification,because the classification of BIM model information by different roles determines the format of information coding.Based on this,this paper first introduces three kinds of information classification methods:tree classification,face classification and hybrid classification,and then proposes three coding methods:hierarchical code,combined code and composite code.Finally,it explains how to realize data transmission between multiple software through cases,and attaches self-defined classification code to Revit's object attributes,so as to provide the same set of classification code to the project participating units,guide them to carry out collaborative work,and ensure the effective transmission of information.
