几何学
Here you can pass the polygon geometry into the Node whose points, edges or surfaces you want to extrude. To extrude splines, you can use the Extrude Line Node.
在这里，您可以将多边形几何体传递到要挤出的点、边或表面的 Node 中。要挤压样条，可以使用“挤压线节点”。
模式
Here you can select if points, edges or polygons should be extruded.
在这里你可以选择如果点，边缘或多边形应该挤压。
选择
If you don’t want to extrude all of a geometry’s elements, you can create a selection whose points, edges or polygons should be used. An Index Array From String Node can be used in conjunction with this where you can enter the indices of the points, edges or polygons to be extruded. Alternatively, the Extrude function also automatically uses a selection from an Active Selection Node in the event no Selection has been linked to the Node.
如果你不想挤出一个几何体的所有元素，你可以创建一个选择，其中的点，边或多边形应该使用。一个来自字符串节点的索引数组可以与此结合使用，您可以输入要挤压的点，边或多边形的索引。或者，在没有选择被链接到节点的情况下，挤出功能也会自动使用活动选择节点中的选择。
偏移量[-∞ . . + ∞ m ]
This value defines the distance with which the extruded elements should move from the original surface.
这个值定义了受挤压元件应该从原始表面移动的距离。
偏置变差[-∞00. . + ∞00% ]
This setting can be used if not all extruded elements should have the same Offset. Offset Variation defines the maximum divergence from the Offset value as percentage. The maximum extrusion will in any case be defined by the Offset value. The Offset Variation value only defines the smallest possible offset.
如果不是所有的挤压元件都应该有相同的偏移量，这种设置可以使用。偏移量变化将偏移量值的最大偏移量定义为百分比。在任何情况下，最大挤压将由偏移量值定义。偏移量变化值仅定义可能的最小偏移量。
插入[-∞ . . + ∞ m ]
This value applies to extruding points and defines the distance around the original point that serves as the basis for the extrusion. If you imagine the extrusion result as a pyramid, the base of the pyramid would be defined by the Inset value.
此值应用于挤压点，并定义作为挤压基础的原始点周围的距离。如果将挤压的结果想象成一个金字塔，金字塔的底部将由插入值定义。
插入变化[-∞00. . + ∞00% ]
This value only affects the extrusion of points and generates a variation of the Inset value for each extruded point.
这个值只影响挤压点，并产生了每个挤压点的插入值的变化。
细分[0. . 2147483647]
This setting can be used to define the subdivision of edges or polygons along the Offset extrusion.
这个设置可以用来定义沿偏置挤压边缘或多边形的细分。
If Per Step is enabled, the number of subdivisions will be used as a multiplier for the Offset value. The extruded elements will be moved correspondingly further. When extruding points, the Subdivision value defines the number of additional subdivisions for each surface bordering that point.
如果启用了 Per Step，将使用细分数作为抵消值的乘数。挤压元件将相应地进一步移动。挤压点时，“细分”值定义每个与该点接壤的表面的附加细分数。
每个步骤
Enable this option if you want the extrusion to automatically be calculated as often as defined by the Subdivision value. The actual distance that the elements will be moved will be a result of the multiplication of the Offset and Subdivision values. This function is not available for the extrusion of points.
如果希望按照“细分”值定义的频率自动计算挤压，请启用此选项。要移动的元素的实际距离将是偏移量和细分值相乘的结果。这个函数不适用于点的挤压。
创建 Ngons
If this option is enabled, additional polygons created via the Subdivision setting will be grouped into an N-Gon for each extruded edge. If Mode is set to Point, only the edges bordering on the original point used will be grouped.
如果这个选项是启用，其他多边形创建通过细分设置将组合成一个 N-Gon 为每个挤压边缘。如果模式设置为点，那么只有原始点的边界将被分组。
Polygons
多边形
使用离岛
When polygons are extruded, all polygons will be handled individually. On curved surfaces, the extruded polygons will separate and will act as protrusions. If the extruded polygons should remain connected to the neighboring polygons, the Use Islands option should be enabled. The Max Angle setting can be used to define the angle at which neighboring surfaces are allowed to extrude separately.
当多边形被挤压时，所有多边形将被单独处理。在弯曲的表面上，挤压出来的多边形将会分开，并充当凸起。如果挤压的多边形应该保持连接到邻近的多边形，那么应该启用 Use Islands 选项。最大角度设置可以用来定义相邻表面允许单独挤压的角度。
最大角度[0. . 180 ° ]
If Use Islands is enabled when extruding polygons, this angle can be used to define the degree to which polygons will be extruded coherently.
如果在挤压多边形时启用了 Use Islands，那么这个角度可以用来定义多边形被一致挤压的程度。
创建帽子
When polygons are extruded, the original surfaces are normally deleted. This results in a type of open box being created where the opening is where the extruded polygon lies. If you want to keep the original polygon, you can enable the Create Caps option. This can, for example, be useful when working with very thin shapes such as a plane in order to give it a certain thickness.
当多边形被挤压时，原始表面通常被删除。这导致了一种类型的开放盒子被创建的开口是在挤压多边形的位置。如果你想保持原来的多边形，你可以启用创建盖帽选项。例如，这可以是有用的，当工作与非常薄的形状，如平面，为了给它一定的厚度。

轮流[-5729577951308232523776.5729577951308232523776 ° ]
When extruding edges, the orientation of the extruded edge can be defined using the Rotation value.
当挤压边缘时，可以使用旋转值来确定挤压边缘的方向。
