In order to solve the technology defects in current dike’s BIM 3D wireframe-modelling method,the dike’s BIM modelling and information framework is proposed based on the characteristics of dike and its modelling needs.It consists of code standard module,naming system,section extraction module and 3D solid modelling module.With the help of such framework,the geometry and corresponding information can be ironed into the same solid BIM model.Autodesk and its subsidiary Civil 3D/Revit are utilized to implement the above framework,while it can also survive in different BIM software platforms.The application results show it can construct the BIM model automatically,which enhances work efficiency profoundly.Moreover,it has a reference significance for the dike’s life-cycle BIM application.
