矩阵挤压

The Matrix Extrude tool is similar to Extrude, but with one difference: you can make as many extrusion steps as you want in one go. This is achieved by defining a relative value for move, rotation and size, which is then applied at each step.

矩阵挤压工具类似于挤压，但有一个不同之处: 你可以一次性完成任意多的挤压步骤。这是通过定义一个相对值的移动，旋转和大小，然后应用于每一步。

Matrix Extrude can be applied to polygons. The polygons are extruded individually — groups of surfaces are broken apart. If you have not selected any surfaces or if you are not in polygon mode, then all surfaces of the active object are automatically used.

矩阵挤压可以应用于多边形。这些多边形是单独挤压出来的，一组表面是分开的。如果您没有选择任何表面，或者您没有处于多边形模式，那么将自动使用活动对象的所有表面。

To use Matrix Extrude interactively, drag within the viewport. While you drag, you can also use the following keys for additional functionality:

若要交互使用矩阵挤出，请在视区内拖动。当你拖动的时候，你也可以使用下面的键来实现额外的功能:

Shift +drag to adjust the Size value.

移动 + 拖动来调整大小值。

Ctrl +drag to adjust the Rotate value.

拖动可调整旋转值。

Alt +drag to move in the Z direction.

拖动 Alt + 来向 z 方向移动。

A couple of examples will help to illustrate the versatility of Matrix Extrude. For the first example, select a side of a cube and then apply the Matrix Extrude function with one of the default values:

下面的几个例子将有助于说明矩阵挤压的多功能性。对于第一个例子，选择一个立方体的一面，然后应用矩阵挤压函数的默认值之一:

The side will be extruded a total of eight times. With each extrusion step, the surface will be moved 50 m in the Z direction. Furthermore, it will also be scaled by a factor of 0.8 on each axis per step. Additionally, at each step it will be rotated by 10° around the H axis (Heading).

这一方将共挤压八次。随着每一个挤压步骤，表面将移动50米的 z 方向。此外，它还将按每一步每个轴上0.8的系数进行缩放。此外，在每一步，它将围绕 h 轴(标题)旋转10 ° 。

For the second example, create a sphere and make it editable by choosing Mesh / Conversion / Make Editable. Choose Mesh / Create Tools / Matrix Extrude, enter the values shown below and click OK to apply the matrix extrusion and create the hairy sphere.

对于第二个示例，创建一个球体，并通过选择 Mesh/Conversion/Make Editable 使其可编辑。选择“网格/创建工具/矩阵挤压” ，输入下面的值，然后单击“确定”应用矩阵挤压并创建毛球。
