圆弧插值样条的约束生成方法及其应用

Arc Spline Interpolate Based on Constrained Method

利用具有参数化设计、特征造型能力的ＣＡＤ系统中构形的约束功能与方法，给出了一种圆弧插值样条曲线的约束生成方法。这种方法并不需要或依赖系统的曲线造型功能，并可局部调整，尤其对缺乏曲线造型功能的ＣＡＤ系统构建插值样条将有独到的作用。

In this paper, based on the constrain function provided by the 3D CAD system, an arc spline interpolation method is presented. This method doesn't need curve modeling and is local adjusted and especially fit for the CAD system with which without curve modeling block.
