Maya Nurbs 车轮建模

　　select these 9 center cv#39;s (pic 5) and drag also to -0.235 -z axis (pic 6).

　　选择 9 个 cv 点 (pic 5) 将其在 -z 轴上拉 -0.235 的距离 (pic 6).

　　select these oval shapes (pic 7) and drag to about -0.46 of -z axis (pic 8).

　　选择那些卵形的曲线 (pic 7) ，并在 -z 轴上移动 -0.46(pic 8).

　　now you have front oval shapes (bigger) and oval back shapes (smaller) right? ok nowselectevery set of oval shapes like in pic 9 and loft them (every set of them), then it would look like this pic (pic10).

　　先选择大的卵形曲线，按住 shift 键选择小形卵形曲线 (pic 9) ，一组一组的 loft 它们，然后就可得到如下图的结果 (pic 10).

　　nowselectthe other shapes (triangle and small shapes in the center) (pic 11) and then extrude them to -0.5 of -z axis (pic 12). remember : to extrude a curve as nurbs, open your extrude option box andset the style to distance, and make sure output geometry has been set to nurbs

　　现在选择其它曲线 ( 三角形和中心那些小圆 )(pic 11), 然后在 -z 轴上 extrude -0.5 的距离 .

　　记住 : extrude 出来是应该椒 nurbs 曲面，打开你的 extrude 选项，设定距离并确定输出的几何体为 nurbs 曲面 .
