今天小编为大家分享Maya Nurbs汽车方向盘建模教程，教程真的很不错，值得大家学习，一起来看看吧！
翻译说明： 为了让大家更能理解这个教程，我并不翻译其中一些命令，这样可以让一些初学者 ( 不是很熟悉 maya nurbs 建模命令 ) 更快找到这些命令。
希望可以和大家一同进步！！！！！
from front view, create this profile curve (fig 1), and move it to -0.95 of z axis. in this case, i use a measurement of around 5.7 cm (fig 2). use the create measure tools distance tool to check the distance.
在前视窗里创建轮廓曲线 (fig 1), 并在 z 轴方向上移动约 -0.95. 在这个教程里，我的尺寸约为 5.7 cm(fig 2). 你可以使用 create measure tools distance tool 来检查你的尺寸 .

from side view, duplicate this curve and move the new curve to 0.951 of z axis (fig 3), then tweak this new curves cvs into this shape (fig 4), so it looks smaller than the original.
在侧视图复制曲线，并在 z 轴方向上移动约为 0.951(fig 3), 然后将新复制的曲线移动各 cv 点使其形状像 (fig 4) 所示，可以看出它比原来的曲线轮廓要小。

Next,selectthe 2 curves and go to surface loft (fig 5). OK. Next create a NURBS cylinder with radius 2, height ratio 3, sections 20, spans 12 (fig 6).
接下来，选择这两条曲线并 surface loft (fig 5). Ok. 创建一个 Nurbs 圆柱体，半径为 2 ，高为 3 ， sections 为 20,span 为 12(fig 6).

Now from side view, rescale the Z value to 0.216 (fig7). Next...click theselectby component type button 
, go to front view andselectthese center CVs (see fig 8).
回到侧视窗，将圆柱体的 z 轴方向缩小到 0.216(fig 7). 接下来选择中间的一些 CV 点 (fig 8).

now move the selected cvs to 1.433 of z axis (fig 9), you can see the cvs axis value in the cvs panel (right side).
将它们在 z 轴方向上移动约 1.433 的距离，你可以在右边通道栏里看到数值 .

next,selectyour lofted object, shift-select the cylinder, go to edit nurbs surface fillet circular fillet option box and apply these settings (fig 10). note : use 0.0010 for positional tolerance for betterfillet tolerance, hit fillet, then youll have this figure (fig 11).
接下来，选择你 loft 成的曲面，按 shift 键选择圆柱体，到 edit nurbs surface fillet circular fillet option box 选项框里运用这个设置 (fig 10).
记住 : 使用 0.0010 的数值给 positional tolerance ，这样你就可以得到 (fig 11).

next,selectthe cylinder, go to edit nurbs trim tools ,selectoneof the white trim areas (fig 12), rotate your camera view to back side,andselectback center area (fig 13) then hit enter.
接下来，选择圆柱体，到 edit nurbs trim tools, 选择要保留的曲面区域，如 (fig 12)(fig 13) 所示，然后 trim 它。

next,selectthe lofted object, go to edit nurbs trim tools ,selectone of center top areas (fig 14) then hit enter (fig 15).
选择 loft 出来的曲面，到 edit nurbs trim tools, 选择要保留的曲面区域，如 (fig 14)(fig 15) 所示，然后 trim 它。

next from front view, create a nurbs torus with radius 3.8, sections 22, height ratio 0.08, rotate it to 90%26deg; of x axis (fig 16), thenselectthese 4 cvs and rescale them a little bit towards the center (use left manipulator to rescale them) (fig 17).
回到前视窗，创建一个 nurbs 圆环，半径为 3.8,section 为 22 ， hight ratio 为 0.08, 并在 x 轴方向上旋转 90 度 (fig 16), 选择这 4 个 cv 点并将它们向中心方向拉伸一点 .(fig 17)

next, create a nurbs circle with 18 spans, rotate it to around -41.676%26deg; of z axis and rescale to 0.238 of z scale, translate it to -2.484 of x axis and -2.736 of y axis (fig 18). next, you need to duplicate and rotate this curve several times towards the top left side and tweak some cvs (see fig 19).
接下平，创建一个 nurbs 圆曲线， span 为 18, 并在 z 轴方向上旋转 -41.676 度，并将 z 轴方向缩小到 0.238, 在 x 轴方向上移动到 -2.484 ， y 轴移动到 -2.736(fig 18). 接下来你需要复制一些曲线并旋转移动到 (fig 19) ，适当移动它们的一些 cv 点。

fig 19
next,selectall of these curves sequentially and go to surface loft (fig 20). next create a nurbs cylinder with 16 sections, 4 spans, height ratio 2, rotate it to 90 of x axis, scale it 0.462 of x axis, rotate it to around 30.818%26deg; of z axis, and then rescale one row ofthe outer cvs. rescale them very small until it looks like they are touching each other (fig21). 按顺序选择这些曲线并 surface loft (fig 20). 接下来创建一个 nurbs 圆柱体， sections 16 ， 4spans, height ratio 2, 并在 x 轴方向上旋转 90 度 ,x 轴方向上缩小到 0.462, 在 y 轴方向上旋转 30.818 度，并拉伸一些 cv 点到看上去都接触到一起。
