摘要
为了更好将建筑信息模型(BIM,Building Information Modeling)技术运用在线路空间结构物的全生命周期中,运用Autodesk Revit软件平台,建立框架桥包括框架身、翼墙、基础、泄床及顶部附属工程等主要组成部分的参数化"族"模型。利用Auto CAD Civil3D二次开发功能创建轨道模型并导入Revit中。根据各部分的控制参数、几何约束条件及关联关系装配整体框架桥BIM参数化模型,并将所创建的模型导入Lumion软件中实现模型的三维动态漫游展示,为该类桥梁结构的三维可视化展示提供了新的方法与理念。
To use BIM technology better in the whole life cycle of railway space structures, this paper built parametricfamily models of main parts of frame bridge including body,wing wall, foundation, leak bed and appurtenant workson the top of bridge by Autodesk Revit. The track model was created and imported into Revit by using the seconddevelopment function of AutoCAD Civil3D. BIM parametric models of the intact frame bridge based on each part’scontrol parameters, geometric constraints and relationshipswere assembled. Three-dimensional dynamic roaming show ofthe models were implemented by importing the created model into Lumion software. This paper provides new method andtheory for 3D visualization show of this bridge structure.
