摘　　要：随着计算机技术的不断发展,异形形体的建筑成为建筑设计师美学灵感在现实世界的直观体现。三维曲面作为异形建筑形体不可或缺的一部分,然而按照曲面曲率生产的非标构件在安装定位时往往存在定位困难和安装尺寸偏差较大等问题。针对这一问题,对一种三维曲面二维平面化方法进行了研究,使用该种方法生成的二维单元板块模型进行精确定位和尺寸计算可以指导施工建造,避免了工程材料的浪费。验证结果表明:项目案例中采用在Grasshopper中控制划分数量后通过连接3个或4个单元角点的方式生成了有缝隙和无缝隙的2类二维平面单元板块,验证了该种方法具备较好的应用可行性。同时,分析了该种方法在应用过程中存在的问题并给出了解决方法,为三维曲面二维平面化提供了一种技术思路。With the continuous development of computer technology,the building of shaped forms has become a real-world visualization of the aesthetic inspiration for architects.Three-dimensional surfaces are an integral part of shaped architectural forms,however,non-standard components produced according to curvature of the surface are often difficult to locate and have large deviations in installation dimensions.As to this problem,A two-dimensional planar technique for three-dimensional surfaces is under study,and the two-dimensional unit plate model generated by this method for accurate positioning and size calculation can guide the construction,avoiding the waste of engineering materials.The validation results show that two types of two-dimensional planar unit plates with and without seams are generated by connecting 3 or 4 cell corner points after controlling the number of divisions by using Grasshopper in project case,which verifies that this method has good application feasibility.Meanwhile,the problems in the application of this method are analyzed and solutions are given,which provides a technical idea for two-dimensional planar technique for three-dimensional surfaces.
