随着现代工程技术的发展,设计变得越来越复杂,也需要越来越多的专业参与到其中,那么就更需要对同一个模型和相同的数据进行分享。信息化是这个社会的趋势,当然也是设计行业的趋势,BIM就是建筑信息化,BIM是整个建筑生命周期的建筑信息模型化,从规划到设计、到施工、再到设备维护运营,甚至到建筑的拆除,在这整个周期中,设计是上游阶段,因此,BIM在设计阶段应用的是否成功决定了BIM在其他阶段的应用的连续性和有效性。也就是说,BIM在设计行业的发展影响着BIM在建筑行业的发展。-With the development of modern engineering technology, design becomes more complex, more and more professionals need to participate in them, then the more the need for the same model and the same data sharing. Information is the tendency of this society, of course, the design industry trends, BIM is a building information, BIM is a building information modeling throughout the building s life cycle,　planning to design, to construction, to equipment maintenance operations, even to the building removal, in this whole cycle, the design is the upstream stage, therefore, BIM applications in the design phase determines the success and effectiveness of continuity BIM applications in other stages. That is, BIM design industry in the development affects the development of BIM in the construction industry.
