面向对象的建筑构件信息建模

OBJECTORIENTED INFORMATION MODELING OF ARCHITECTURAL ELEMENTS

本文针对国情，运用面向对象的技术、基于特征的建模方法，研制建筑工程集成信息模型原型系统中的建筑构件库。它利用特征层次结构组织特征信息，提出了适用于建筑建模的几何表示法：线框－连环－蒙面的混合建模方法。采用以虚面为核心的数据结构，通过虚面的依附关系建立和检索构件特征之间的安装关系，实现了参数化的建筑构件的特征建模。

Based on the study of existing architectural design systems and the general requirements of AEC industry in China, a feature-based and object-oriented prototype system for building design is developed. It makes use of a hybrid model of wireframe and solids with the emphasis on wireframe and skinning techniques. The building model under development is supposed to be an integral part of the integrated product in formation model which is capable of supporting all aspect of design and construction activities in whole life cycle of a building.
