中文摘要：

本文基于Revit管线批量自动标注的实际工程要求,将平行管线标注分为无变径标注和有变径标注两类,并且阐述了会导致管线发生变径的三种情况。针对不同的管线排布情况分别采用了相对应的管线自动标注方法。本文还提出了一种利用引垂线的方法解决了多变径平行管线批量标注问题。实验结果表明,该类方法可以快速高效地对管线进行标注,与传统的标注方法相比,简化了操作,提高了标注效率,为以后二次开发提供了一定的经验。

英文摘要：

Based on the actual engineering requirements of Revit pipeline auto-labeling,this paper divides parallel pipeline labels into two categories of no-adjustable and adjustable parallel pipeline labels and describes three situations which will lead to pipeline diameter changes. In addition,the paper puts forward a method of using lead vertical to solve the problem of the changeable diameter parallel pipes labeling. The experimental results show that：this kind of labeling methods greatly increase labeling efficiency,and compared to the use of Revit interactive interface,they simplifies the operation,improve the labeling efficiency and provide some experiences for secondary development in the future.
