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. 中国教育网

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 . www.edu-cn.com

From side view, duplicate this curve and move the new curve to 0.951 of Z axis (fig 3), then tweak this new curve's 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, select the 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).

Now from side view, rescale the Z value to 0.216 (fig7). Next...click the select by component type button , go to front view and select these center CVs (see fig 8). 漂亮MM女性网

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). www.edu-cn.com

Next, select your 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 better fillet tolerance, hit fillet, then you'll 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, select the cylinder, go to edit nurbs > trim tools , select one of the white trim areas (fig 12), rotate your camera view to back side, and select back center area (fig 13) then hit Enter. edu4u.com.cn

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 from front view, create a NURBS torus with radius 3.8, sections 22, height ratio 0.08, rotate it to 90° of X axis (fig 16), then select these 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° 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。

Next, select all 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° of Z axis, and then rescale one row of the outer CVs. Rescale them very small until it looks like they are touching each other (fig21). www.edu-cn.com

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 ， 4 spans, 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。
