摘要
利用程序化ＣＡＤ技术描述三维空间曲屋面造型并进行模拟显示，其实体模型能随意平移、旋转、缩放和修改，无需复杂的计算即可得到多个定位控制点．可为选择和确定方案提供方便。
The pattern of curve roof in 3D-space is described with CAD-routed techniqueand imitation is shovvn. Solid modeling can be translated,arbitrarily rotated,scale reducedand revised.The control of several locations can be got without.complicated computation.Therefore,it is convenient for the business owner to select and decide the plan. Better condi-tions will be applied for engineering design and construction.
