基于市政项目综合管线坡向模型创建的二次开发研究应用

Research&Application of Secondary Development Based on Comprehensive Pipeline Slope Model of Municipal Projects

市政行业采用BIM技术辅助项目建设已十分常见,相关BIM应用对模型精度的要求也越来越高。轨道交通地下站点和地下综合管廊等主体较长、自身结构存在坡度的工程项目,对建筑内部机电管线模型的坡向建模提出更高的要求。研究借助Revit二次开发,将平整的管线模型整体放坡,保证模型放坡后系统连接的完整性,避免直接按照给定的坡度手动建立带坡度的机电模型,提高管线坡向建模的工作效率。

It is very common for the municipal industry to use BIM Technology to assist project construction,and the requirements of relevant BIM applications for model accuracy are also getting higher and higher.The engineering projects with long main bodies and gradient of their own structures,such as underground rail transit stations and underground pipe galleries,put forward higher requirements for slope modeling of electromechanical pipeline models inside buildings.With the help of the secondary development of Revit,the flat pipeline model is graded as a whole to ensure the integrity of the system connection after the model is graded,to avoid directly establishing the electromechanical model with slope according to the given slope manually,and to improve the efficiency of pipeline slope direction modeling.
