| 摘 要： | Although there are modifying modules in the most CAD software, the parameters of entire curve must be computed again as the tiny local curve changed. The modification are not local and spending long time and difficult as the eurve is complex or large. A method can be applied to engineering designer easily has been proposed. There are only four segments have been ehanged along with the moving of a given point, and the speed is fast. It ean be used to CAD software and generalize the method to surface easily.
