摘　　要：对与两异面直线等距离点构成的工程曲面 ,本文介绍以画法几何原理为基础的建模方法及其数学模型 ,使建模过程可视化。本文所建模型对所有异面直线经投影变换均只需代入不同的 P和Φ值 ,故具有简单通用的优点。本方法还可供精确尺规作图 。The equilateral hyperbolic paraboloid is a complex nondevelopable straight engineering surface. This paper presents a modeling method based on descriptive geometry theorem and its mathematical model, which makes the process of modeling visible. This method not only makes drawing with ruler and compass more precise in theory, but also makes Computer Graphics (CG) easier to realize.
