Mirror Selection

镜像选择

This command can be used to mirror polygonal objects’ point, edge or polygon selections (and their respective UV equivalents) in 3D space using a definable mirror plane. This also works with point selections for splines.

这个命令可以用于使用可定义的镜像平面在3D 空间中镜像多边形物体的点、边或多边形选择(以及它们各自的 UV 等价物)。这也适用于样条的点选择。

For UV elements whose selections are synchronized to elements in the Perspective Viewport (and vice-versa), mirror planes and selections will be calculated entirely in 3D.

对于 UV 元素，它们的选择是与透视图窗口中的元素同步的(反之亦然) ，镜像平面和选择将完全计算在3D 中。

The mirroring of selections works best with symmetrical objects. However, a definable tolerance can also be circumvented with asymmetrical objects.

选择的镜像对于对称的物体效果最好，但是对于不对称的物体也可以规避可定义的容差。

Tip: 提示:
 A geometry point can have multiple UV points. This is the case for points that lie on a UV Seam and in turn can share this UV point with multiple UV Islands. Differences in the mirroring process can therefore occur, depending if you made the selection in the Perspective Viewport or in the Texture UV Editor. 一个几何点可以有多个 UV 点。这是一个紫外线接口上的点的情况，反过来可以与多个紫外线岛共享这个紫外线点。因此，镜像过程中可能会出现差异，这取决于您是在透视视口中还是在纹理 UV 编辑器中进行选择

Parameter

参数

Space

太空

Here you can define the space in which the mirror plane - its origin - should be positioned:

在这里，您可以定义镜面(其原点)应该放置的空间:

Mirror Plane

镜面

Here you can define the mirror plane within the coordinate system of the Space setting. The plane will lie at the respective coordinate origin.

在这里你可以定义的空间设置的坐标系平面的镜子。平面将位于各自的坐标原点上。

Tolerance

宽容

You will normally use this tool with symmetrical objects, which means that you will not have to deal with the Tolerance value. This setting, however, is useful if a selection should be mirrored that is not quite symmetrical. For each point of the selection, a check will be done to see if the opposite element lies within the defined tolerance so the selection can indeed be mirrored. If a point cannot be found within the defined tolerance, nothing will be selected. The Tolerance value should then be increased.

您通常会使用这个工具与对称的对象，这意味着您将不必处理的公差值。但是，如果选定内容应该镜像为不完全对称的内容，则此设置非常有用。对于选择的每个点，将进行检查，以确定相反的元素是否位于已定义的公差范围内，从而确实可以镜像选择。如果在规定的公差范围内找不到一个点，则不会选择任何值。然后应该增加公差值。
