基于Revit平台的墙体模型自动生成算法

Revit platform based automatic generation algorithm of wall model

分析了施工图图元组成,通过过滤图层以及图元类型提取墙线图元信息;重点对重叠弧线进行分类并提出处理重叠线的方法;对表示弧形墙体的同心弧线进行分类,提出获取弧形墙中心线以及墙体厚度的方法。基于Revit平台,利用C#语言进行程序开发,实现墙体的自动生成,验证了算法的可行性,提高了墙体模型的建模效率及准确性,实现了墙体模型的三维重建。

This article analyzed the composition of construction drawing elements,and extracted the wall line element information by filtering layers and element types,focused on the classification of overlapping arcs and put forward the methods to deal with them,classified the concentric arcs representing the arc wall,and proposed a method to obtain the center line of the arc wall and the wall thickness.Based on the Revit platform,the article used the C#language for program development,and implemented the automatic generation of the wall,which verified the feasibility of the algorithm,at the same time,improved the efficiency and accuracy of the wall model modeling,and realized the 3D reconstruction of the wall model.
