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 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).

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 the select by component type button , go to front view and select these 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).

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 .
