摘　　要：曲线造型是刺绣CAD系统的基础,本文归纳分析了该场景下的应用需求,提出采纳Bézier三次有理曲线作为造型曲线,并对曲线段之间在边界条件下产生的"突变问题"提出了一个基于线性函数的方法以约束曲线段之间的突变。该方法已应用到实际系统中,效果很好。Curve sculpt is the major role of embroidery CAD. to adopt so as to meet such needs. A new approach based on problem＂, which happens in the boundary between the two and the experiment result indicates that it is effective. The requirement is analyzed and bezier curve is proposed linear function is presented trying to deal with the ＂break segments. This method is experimented in a real system
