Research on Fast Stretching Algorithm for Linear BIM Model of High-speed Railways

针对目前BIM软件在建模过程中存在的难以快速对实体进行拉伸的问题,提出了BIM软件中的快速拉伸算法,包括二维平面曲线离散转三维空间曲线算法和平面空间变换几何算法;开发出针对高速铁路项目的专用BIM模型拉伸工具,实现了高速铁路线性BIM模型的快速拉伸;基于所提算法在实际高速铁路项目中开展了区间三维设计,实现了高速铁路线性BIM模型的快速创建,且设计效率提高了100%。

Aiming at the problems that were difficult for BIM software to stretch the solid quickly in the modeling processes at present,a fast stretching algorithm was proposed in BIM software,which including the 2D plane curve discretizated to three-dimensional space curve algorithm and the plane space transformation geometry algorithm.A specific BIM model stretching tool for high-speed railway projects was developed to realize the fast stretching of linear BIM model for high-speed railways,and the interval 3D design was carried out in the actual high-speed railway projects based on the proposed algorithm.The linear BIM model of high-speed railway was established quickly,and the design efficiency is improved by 100%.
