摘要: 服装纸样CAD设计涉及到许多修改,其中一个主要修改模块是自由曲线的修改,但目前CAD软件中的修改模块有许多不足。结合服装纸样CAD设计线型修改的实际情况,提出了一种新的型值点修改方法,该方法利用三次均匀有理B样条构造,修改时曲线能随着鼠标移动而快速改变形状。这种方式直观,符合设计人员的习惯。同时修改有很好的局部性,不需要将整个曲线进行重新计算,所以可控性好,有很强的灵活性,便于设计人员使用。

Abstract: The design of garment pattern CAD relates to many modification methods,one of which is free curve modification.However,many modification modules in the present CAD software have drawbacks.Taken into consideration the practical needs in the curve modification of the garment pattern CAD,a new model value point modification method was proposed. This method was based on thrice uniformity B sample strip constitution,the shape of curve can be changed swiftly with moving of the mouse.It is visual,accords with the habits of designers.It can be applied to modification of part of a curve with no need for recalculating the whole curve.Therefore,this method has the advantages of good controllability,high flexibility,and easy operation.
