摘　　要：目前产品的造型设计普遍采用G1或者G2连续的方式进行曲线或曲面之间的过渡,汽车造型设计中的某些地方会要求使用G3连续来过渡,比如侧面的主腰线、引擎盖上的特征线等。连续性的等级越高,意味着曲线或曲面之间过渡得越平顺和光滑,体现在实物上的视觉效果越好。文章主要研究G3连续在除了汽车之外的一些产品造型设计中的运用。通过对G3连续原理的解释、Alias软件中G3连续的做法、以及G3连续在产品设计中的一些实际运用,来论证G3连续在产品造型设计中的可行性及给造型效果带来的改善与提升。At present,the product modeling design generally adopts G1 orG2 continuous method for the transition between curves or surfaces.G3 continuous is required in some places of automobile modeling design,such as the main waist line on the side,the characteristic line on the bonnet,etc.The higher the level of continuity,the smoother the transition between curves or surfaces,and the better the visual effect reflected in the real object.This paper mainly studies the application of G3 continuous in some product modeling design except automobile.Through the explanation of G3 continuous principle,the practice of G3 continuous in alias software and some practical applications of G3 continuous in product design,to demonstrate the feasibility of G3 continuous in product modeling design and the improvement as well as the promotion of modeling effect.
