| 摘 要： | 针对机场ＣＡＤ系统开发的需要，研制了采用孔斯曲面构造的机场场道区三维曲面模型与传统骨架模型和格网高程模型相比，具有更加规范的表达形式，而且能够更加准确地描述在此范围内的复杂设计表面及结构物基底面。该模型的基本功能采用面向对象程序设计方法实现，已在机场ＣＡＤ系统中得到应用。

| Abstract: | In this paper the 3D model for the roads in airport CAD system with Coons surface model is mainly discussed. Compared with traditional strip and grid model, the expression is more normal and can accurately describe the design surface and the Construction Ground base. The basic calculation method and OOP method used to realise the class hierarchy structure were also introduced and applied in roads in airport CAD system. |
