摘要：

In this paper, we provided a new method which used Genetic Algorithm to produce offsetting two-dimensional NURBS curves parameter optimization method is used for approximating offset curves. The objective function being minimized is the explicit summation of square of errors at sample points piecewise processing yields valid profiles, the results that Genetic Algorithm is more efficient than traditional methods.
