The purpose of this paper was to study the function of dart transier in the ET2007 CAD system by conducting considerable transfer experiments on the female top basic block. The dart transfer methods using dart transfer tool, intelligent pen, and rotating tool were found. The characteristics and appropriate occasions of the dart transfer methods were pointed out. The results also show that there are still some problems on the function of dart transfer in the ET2007 CAD system. Countermeasures were proposed which could make all kinds of dart transfers complete smoothly.%为研究ET2007服装CAD打版系统的转省功能，在文化式女装上衣原型上进行了大量的转省实验，找到了用转省工具、智能笔和旋转工具实现转省的方法，总结了各自的特点及其适用场合，并针对在实验中发现的问题提出了对策，使各种类型的转省设计都能顺利完成．
