镜像工具沿选定轴向镜像选中元素。

The Mirror tool in Edit Mode is similar to Mirroring in Object Mode. It is exactly equivalent to scaling vertices by -1 around one chosen pivot point and in the direction of one chosen axis, only it is faster/handier.

After this tool becomes active, select an axis to mirror the selection by pressing X, Y, or Z.

还可以在激活工具后，按住 MMB 并拖动来交互式选择镜像方向。

对称轴

可以指定镜像轴为坐标系的三个轴向之一。

As you can see, the possibilities are infinite and the freedom complete: You can position the pivot point at any location around which we want the mirroring to occur, choose one transformation orientation and then one axis on it.

轴心点

Pivot points must be set first. Pivot points will become the center of symmetry. If the widget is turned on it will always show where the pivot point is.

In Fig. Mirror around the individual origins. the pivot point default to median point of the selection of vertices in Edit Mode. This is a special case of the Edit Mode as explained on the pivot point page.

In Fig. 沿3D游标镜像。 the pivot point is the 3D Cursor, the transformation orientation is Local, a.k.a. the object space, and the axis of transformation is X.

变换坐标系

Transformation Orientations are found on the 3D Viewport header, next to the Widget buttons. They decide which coordinate system will rule the mirroring.
