所谓四维设计,是在建筑三维空间模型的基础上引进时间轴度量的第四维度来协助完成建筑的设计与建造,通常借助计算机技术用四维数字模型即4D模型来表达。四维设计的研究目标完全是针对提高建筑行业设计和建造效率而言,同时四维设计有着鲜明的建筑行业特征,与制造行业的三维设计模式差别较大。
The so-called four-dimensional design is based on the three-dimensional model of the building to introduce the fourth dimension of the timeline measurement to assist in the completion of the design and construction of the building, usually by means of computer technology with four-dimensional digital model or 4D model to express. The research goal of four-dimensional design is totally aimed at improving the design and construction efficiency of the construction industry. At the same time, the four-dimensional design has distinct characteristics of the construction industry, which is different from the three-dimensional design pattern of the manufacturing industry.
