| 摘 要： | 利用三维CAD软件提供的API工具,对给定的任意曲线方程进行读取和分析,然后采用离散和拟合算法,在指定的草图平面中绘制出光滑的曲线,为进一步在三维CAD环境中精确地完成复杂曲面的三维造型,提供一种草图绘制工具。这有利于实现复杂机械零部件的造型和设计。

| Abstract: | The method to generate curves with arbitrary equations in the 3D CAD system is introduced.The given curve equation is read and analyzed,and the algorithms for curve discretizing and fitting are applied.Then the smooth curve is obtained in sketch plane.Thus a tool for draw arbitrary curves is offered for generating complex surfaces of the parts. |
