Abstract: In this paper, ArchiCAD is used as the BIM design platform to carry out modular design for all kinds of sewage plant monomer models. A set of parametric modeling plug-ins for sewage treatment structures is developed. The plug-ins has built-in related professional calculation formulas. Users can one-click quickly generate BIM model that meets the requirements of bidding and preliminary design stage by entering the basic process parameters. When the design scheme needs to be modified, the model can be edited twice. The 2D drawings generated by cutting the model will be changed synchronously. This group of parametric modeling plug-ins can effectively help designers improve work efficiency and reduce repetitive modeling work.

近年来,BIM技术应用较为广泛,在可视化展示、协同设计、出图等方面有着明显优势,利用BIM技术进行施工指导有利于不同专业间的协同设计与复杂工程的顺利进行。然而搭建BIM模型的工作量较大,搭建过程占用了大量时间,而且在调整设计方案时往往会产生一些重复性工作,增加了设计人员的负担[1-3]。目前市面上鲜有针对污水厂构筑物的辅助设计工具,给相关设计工作带来了困难。因此,快速建模成为提高BIM设计效率的重中之重。
本研究选取构筑物较为复杂的污水处理厂项目,采用ArchiCAD为BIM三维设计平台,将各类工艺构筑物进行参数化编程,开发出的系列插件可在输入工艺参数后快速生成能够满足投标及初设深度的构筑物模型,实现快速建模以提高设计人員的工作效率;同时,生成的模型也易于二次编辑,方便水工艺设计图的修改。……
