基于工业基础类标准的参数化实体模型 数据交互技术

IFC Standard-based Parametric Data-exchange Method for Solid Model

摘要:

针对已有技术参数化程度低、信息易丢失的缺陷，提出了基于工业基础类 （IFC）标准的参数化实体模型数据交互技术。确立了实体模型IFC格式文件的基本框架，研究了实体模型各类信息的参数化IFC格式数据表达方法，并通过软件编程实现。结果表明，该参数化实体模型数据交互技术可准确描述复杂实体模型，生成的IFC格式文件可在各主流BIM软件中准确表达并能二次编辑。

Abstract:

A parametric data-exchange method for solid model is described based on industry foundation class （IFC） standard aiming at the defects of previous technique such as lack of parameterization level and severe information losses. A basic framework of IFC formate file is put forward， and specific data-exchange methods for all kinds of information of solid model are respectively studied and successfully applied by programming. The software test results show that the parametric data-exchange method could correctly describe the complex solid model and the output IFC formate files can be correctly opened and edited in main building information modeling （BIM） platforms.
