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。

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,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。

next to smooth the connection between the center object and the main torus we need to fillet them together.selectthe left lofted object, shift-select main torus, then go to edit nurbs surface fillet circular fillet option box and apply these settings (fig 40), then you will have this (fig 41).

我们需要在大圆环和握手柄之间得到更圆滑的过渡，选择握手柄再按住 shift 键选择大圆环， edit nurbs surface fillet circular fillet option box ， 选项如 (fig 40), 得到 circular fillet 结果如(fig 41).

fig 41

do the same step with the right lofted object, remember : to circular fillet the right side object, you must turn on reverse primary surface normals.

以同样的方式 circular fillet 右过的握手柄，记住：在 circular fillet 右边时，要打开 reverse primary surface normals 选项。(完)
