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。
In this paper, according to the national conditions, using object-oriented technology and feature-based modeling methods, the building component library in the prototype system of integrated information model for building engineering is developed. It makes use of feature hierarchy structure feature information and proposes a geometric representation method suitable for building modeling: a wire-frame-linked-masking hybrid modeling method. Using the virtual surface as the core data structure, the installation relationship between the component features is established and retrieved through the virtual surface dependency relationship, and the parameterized building component feature modeling is realized.
