镜面
Determines which plane is used as the mirror. ZY is the default since it is used in the front view for objects with vertical symmetry, such as a face.
确定哪个平面用作镜子。ZY 是默认的，因为它用于垂直对称的物体的正面视图，比如人脸。
焊接点
If the Weld Points option is enabled, points at the mirror’s edge are welded automatically — two points become one. This joins the object smoothly, avoiding a seam along the middle.
如果激活焊点选项，镜子边缘的点将自动焊接ー两点合二为一。这样可以顺利地连接物体，避免了中间的缝隙。
公差[0. . + ∞ m ]
Enter the maximum weld radius in the Tolerance box. Points that are within this distance to each other will be snapped together and welded.
在公差框中输入最大焊接半径。在这个距离之内的点彼此将折断在一起并焊接起来。
对称
Enable this option if you want to ensure that the welded points (Weld Points enabled) are placed exactly on the mirror axis. Otherwise, each welded point is placed midway between the points from which it was formed — this may or may not be on the mirror axis depending on whether the points are the same distance from the mirror axis.
如果您想确保焊接点(启用焊接点)正好位于镜面轴线上，请启用此选项。否则，每个焊接点都会位于其形成点之间的中间位置ーー这可能位于镜轴上，也可能不位于镜轴上，这取决于这些点与镜轴的距离是否相同。
To mirror more multiple objects, group the objects together and make the group a child of the Symmetry object. 要镜像更多的多个对象，组对象在一起，使该组的子对称对象

轴上的钳位点
This option is a type of security setting that helps prevent inadvertently moving points lying on the axis very slightly during fine-tuning and this going unnoticed.
此选项是一种安全设置，有助于防止在微调过程中不经意地轻微移动位于轴上的点，这种情况不会被注意到。
The point will snap to the symmetry plane within the tolerance defined and cannot be moved unless this option is disabled.
点将在公差范围内与对称平面对齐，除非禁用此选项，否则不能移动。
删除轴上的多边形
This is also a security setting that prevents degenerated/co-planar polygons from being created on the symmetry axis, as is possible when using the Extrude tool, for example.
这也是一个安全设置，可以防止在对称轴上创建退化/共平面多边形，例如在使用挤出工具时。
自动 flipboard
When modeling, it may be necessary - depending on what is being modeled - to place the mirrored original geometry on the opposite side of the mirror plane. This can be done by clicking on the Flip button or automatically via Automatically Flip. The latter will happen if the view’s camera crosses the symmetry plane when the view is rotated.
建模时，可能有必要——这取决于建模的内容——将镜像的原始几何体放置在镜面的对面。这可以通过点击翻转按钮或通过自动翻转自动完成。如果视图的摄像机在旋转视图时穿过对称平面，就会出现后者。
