数字建筑工程系统的特征建模算法与实现技术

为了支持建筑设计全过程集成 CAD系统 ,创建能够描述和组织建筑设计全过程中各种设计信息和各项设计活动的系统模型 ,提出了一种基于特征的 CSG/B- rep混合建模方法。该方法利用 CSG/B- rep混合建模手段 ,将划分为不同层次的形态模型和活动模型按照一定的关系组织起来 ,并将对象特征按照层次划分置于模型的不同层次上 ,且在模型数据结构的各个层次设置了可扩展数据结构 ,形成了支持建筑设计全过程的可扩展特征数据模型。以该系统模型开发的软件已经说明 ,这种特征建模方法工作效率高、模型适用性强 ,能够实现支持建筑设计全过程的各项工作。

Feature modeling algorithm for digital architectural engineering

This paper proposes a new integrated CAD system and a system model which uses a feature based CSG/B rep mixed modeling algorithm, the model can describe and organize various design information and design processes for the whole architectural design procedure. The algorithm uses the CSG/B rep mixed modeling approach to organize morph and activity models in different levels. The algorithm puts the design object features into corresponding levels in the system model. An expandable feature based data structure supports the whole architectural design procedure. The algorithm has high modeling efficiency and wide application and can support all of the processes in the whole architectural design procedure.
