基于BIM的管线优化方法

BIM技术在综合管线设计中的一个重要功能是解决管道碰撞问题。然而手工绘制调整管道的效率低下,因此本文结合Revit二次开发技术,实现基于BIM的管线快速调整优化。首先对综合管线模型中的图元信息进行提取,构建基于AABB和空间几何的混合碰撞检测算法,识别产生碰撞的管道。然后对综合管线工程设计规范进行参数化处理,提出管线调整优化算法,确定待调整管线和调整范围。实现了碰撞管线的自动调整优化,提高了工程设计效率。

Optimization Method of Pipeline Based on BIM

An important function of Building Information Modeling（BIM） technology in integrated pipeline design is to solve pipeline collision problem. However, the efficiency of manually drawing and adjusting the pipeline is low, so this paper combines Revit secondary development technology to realize the rapid adjustment and optimization of BIM-based pipelines. Firstly, the primitive information in the integrated pipeline model is extracted, and a hybrid collision detection algorithm based on AABB and spatial geometry is constructed to identify the pipeline that generates the collision. Then, the integrated pipeline engineering design specification is parameterized, and the pipeline adjustment optimization algorithm is proposed to determine the pipeline to be adjusted and the adjustment range. Thereby, the automatic adjustment and optimization of the collision pipeline is realized, and the engineering design efficiency is improved.
