【摘要】 非均匀有理B样条曲线(NURBS)已经成为计算机辅助设计及计算机辅助制造的几何造型基础,得到了广泛应用。AutoCAD使用的就是这种NURBS数学模型来创建样条曲线。对AutoCAD中样条曲线的形成原理、产生方法、样条曲线的编辑及转化等进行了探讨,这对于充分利用AutoCAD的功能及对其进行二次开发提供了依据和基础。更多还原

【Abstract】 NURBS has been the geometrical modeling base of CAD&CAM. In this paper, forming principle, produce method, editor and transformation of spline cure in AutoCAD was discussed, which was helpful to making the best use of the function and secondary development of AutoCAD.更多还原
