摘要:本文主要介绍了成都东部新区规划展示中心幕墙工程项目在深化设计优化、加工制造、施工安装各阶段的BIM参数化应用。项目以成都市花——芙蓉花为设计理念，花瓣位置采用了双曲幻彩蜂窝铝板的双层幕墙系统和外倾双曲玻璃幕墙系统，整体造型无明显规律，系统交接面异常之多。因此，项目完全采用Rhino+Grasshopper的BIM参数化方式进行建模、分析、优化和下料，为项目的圆满实施提供了可靠保证。

Abstract: This article mainly introduces the BIM parametric application of the curtain wall project of the new area planning exhibition center in Chengdu east new district in the deepening design and optimization stage, the processing and manufacturing stage, and the construction and installation stage. The design concept of this project is hibiscus, which is the city flower of Chengdu. The petal position adopts the double-skin curtain wall system of double-curved phantom honeycomb aluminum plates and the outwardly inclined double-curved glass system. The overall shape has no obvious regularity, and there are a lot of type of system interface. Therefore, this project completely adopts the BIM parametric method by using Rhino and Grasshopper for modeling, analysis, optimization, and material order, which provides a reliable guarantee for the successful implementation of the project.
