摘要
传统的框架箱涵建筑信息建模(BIM)方法效率低下,数据稳定性无法保证,为了克服传统建模方法的缺陷,介绍一套优化后的建模方法。这套优化的建模方法包含三个部分:采用C#语言编制一个数据转换软件,该软件通过读取RCCAD文本文件,自动生成建模过程中所需数据表格;使用组件应用架构(CAA)开发出一个嵌入达索系统的框架涵涵节及基础批量建模软件,该软件能够自动批量生成以用户定义特征方式存在的涵节和基础模型,内存占用少,效率高;将框架涵端部附属结构封装成一个工程模板,采用META INPUT的方式读入几何元素,采用设计表格的方式选择几何尺寸。采用优化后的设计方法能够大幅度提高建模效率并保证数据稳定性。
Traditional BIM .modeling method for box culvert is inefficient,and the data stability is not guaranteed.To prevent the defects of traditional modeling method,the paper introduced one set of optimized modeling method.This set of method consists of the following three parts:Firstly,programing a data transformation software,which can automatically generate datas table needed in modeling process through the read of RCCAD text files,using C# language;then a box culvert section and base batch modeling software embedded into Dassault system were developed Models were generated by the software perform as user defined features,which takes less memory and the generating process is more efficiently;finally,the end auxiliary structures was packaged into an engineering template by reading geometry components,which was based on META INPUT,and the geometry dimentions were choosen using design table.It indicated that this modeling method could highly improve the modeling efficiency and guarantee the data stability.
