创建自由形体建筑的建筑信息模型

Create Building Information Modeling for Free Form Building

在建筑设计的早期阶段,建筑师常常选择可视化的三维设计软件来表达创意,这些软件具有简便的创建各种自由形体的功能。这时的模型通常在尺寸上是粗略的。得到创意之后,通过对模型在真实环境中的性能分析来确定更准确的局部定位,这些概念设计时的信息能够完整的传递从而进一步完成施工图设计,这些就体现了建筑信息模型(BIM)的核心价值。本文将通过三个部分来讨论如何利用AutodeskRevitArchitecture2010的Conceptual Design实现可视化模型,参数化调整到施工图转换的过程。第一部分参数化模型的设计和调整将探索形体的建立,如何在软件中实现实时可视以及定性定量的调整。第二部分有理化表面处理将探索对自由曲面分割生成网格,通过对网格的个性化定制获取三维构件组成的表面嵌板。第三部分将调整完成后的形体模型转化为建筑构件模型,从而完成施工图的设计。

At the early stage of architectural design,architects used to select visualized 3D design software to represent their ideas. This kind of software is easy to use for creating any free form. At this time,the building model has rough size. After getting an initial idea,architects do performance analysis for the model in real environment and then get a more exact detailed model. Information passed from conceptual design to construction documentation,this is exactly core value of Building Information Modeling. This paper discussed a 3 parts process on how to use Autodesk Revit Architecture to realize visualized model,parameter adjust and construction documentation. The first part＇design and adjust parameterized model＇is focus on form creation; how to visualize model and adjust model by qualitative and quantitative sides. The second part texturized surface explores dividing free form surface with grids and customization grids with 3D components. The third part describes converting the form model to building components and then finishing the construction design.
