[摘要] 在当今的BIM与参数化设计潮流中，结构工程师在复杂建筑的建模方面需要有效的辅助建模工具。犀牛软件与Grasshopper插件提供了快速有效的参数化设计功能。利用该软件与插件编制了一个双层网壳结构快速建模工具，可以自动划分网壳上表面的网格，根据用户输入的网壳高度计算出下弦节点位置，并自动创建所有杆件。本程序作为参数化设计的一个案例，能够为结构工程师开发类似功能提供借鉴。

Abstract: In the trends for BIM and parametric design, structural engineers need efficient aiding tools for modeling of complicated buildings. Rhinoceros software and Grasshopper plug-in provide quick parametric design function. A quick structural modeling tool of double-layer reticulated shells was programmed which could automatically mesh the upper surface of the shell, calculate location of lower chord joints and create all members of the shell.  The program provides a typical case of parametric design and give guide to structural engineers who need develop similar functions.
