摘要
计算机辅助设计是从手工绘图渐进变革而来,其本质是一种方法替代另一种方法。当前,更重要的变革正在发生,那就是电子绘图到建筑信息模型(BIM)的发展。BIM的基础是参数化建筑建模,使用参数以确定一个图形实体的行为,并定义模型组件之间的关系。文章首先探讨参数化建筑建模,并通过案例研究,讨论如何实现参数化建筑建模。
Computer-aided design(CAD) is a progressive step up from manual drafting,but essentially a substitution of one representational methodology for another.A more significant transformation is now occurring as electronic drafting evolves into Building Information Modeling(BIM).BIM's foundation is parametric building modeling which uses parameters to determine the behavior of a graphical entity and define relationships between model components.After explain the connotation of parametric building modeling,this paper probes into how to implement parametric building modeling in six steps and explores parametric building modeling as a knowledge embedding method.Through the case study,how to use parametric building modeling to accomplish BIM is discussed by an example of typical real project(a culture and art center)in Autodesk Revit.Parametric building modeling is a powerful method to model intelligent objects and their intended design behaviors.Characteristics,limitations and difficulties of parametric building modeling are summarized,opportunities and challenges for China are put forward in this paper.
