摘要:在利用BIM技术进行设计时，木结构与其他类型建筑相比，具有大量的孔槽与衔接部位需要作精细化处理。为实现木结构建筑设计时的参数化建模工作，解决大量孔洞与凹槽建模、材质信息设置、操作流程繁杂等系列难题，本文基于Revit提供的API程序命令与外部C# 编程技术进行交互，并设计程序代码来接收或运用数据，避开了手动绘制模型、依赖第三方插件进行模型处理等低效率方法，为木结构设计工作提供了凹槽与孔洞等复杂构造的自动建模、参数变量的接收与运用、材质自动匹配、模拟分布建模可视化过程等自动化思路，逐步实现了木屋顶构造部分的参数化建模工作。同时，本文依据规范设计了相关算法，设计了部分程序参数的取值，通过工程实例证明了程序的可执行性。

Abstract: Wood structure has a number of holes and slots and connecting parts needed to be refined compared with other types of buildings when using BIM Technology for design. The paper aims to achieve the parametric modeling of wood structure building design, and encounter a series of challenges such as modeling a large number of hole and groove, setting material information, and processing complicated operation, etc. Based on the API program commands provided by Revit interacting with external C# programming technology, this paper designs program code to receive or use data to avoid the manual drawing of model and data. What's more, relying on the third-party plug-ins for model processing and other inefficient methods, the paper realizes automation for the wood structure design, which include the automatic modeling of complex structures such as grooves and holes, the receiving and application of parameter variables, the automatic matching of materials, and the simulation of distributed modeling visualization process, etc. From all the work above, the paper gradually manages the parametric modeling of the wood roof structure. Meanwhile, this paper designs the relevant algorithm according to the specification and the values of some program parameters, which further provides a practical case to prove the program's executable.
