A short exposition on the development of multidisciplinary 3D models! The concept of developing 3D virtual models for the purpose of executing a building project was not there for long instead it is a new trend that have been optimized by AEC professionals for streamlining building activities or methods. Until BIM’s presence in the industry CAD software served the purpose of developing models. But modeling process was soon dominated by BIM software such as Revit in context of construction industry. Huge amount of information and data is needed by BIM modelers for developing multidiscipline 3D models. In other words design data or information is required by the modelers of service providing company for the execution of modeling services.
Be it architectural, structural or MEP model, they are all developed on the basis of the design developed by relevant engineers. On the other hand multidiscipline 3D models are created on the basis of design created by architect, structural engineer or MEP engineers. So the information related to the design is always present in the CAD drawings which are developed by the technicians at the time of drafting process. In other words execution of
