Shearing is a form of movement where parallel surfaces move past one another. During this transform, movement of the selected elements will occur along the horizontal axis of the current view. The axis location will be defined by the Pivot Point. Everything that is “above” this axis will move (shear) in the same direction as your mouse pointer (but always parallel to the horizontal axis). Everything that is “below” the horizontal axis will move in the opposite direction.

Warning

The Axis and Axis Orthographic cannot be the same axis, else the imaginary plane is dimensionless and the objects will disappear into a point.

不同轴心点下的切变效果。

The three frames of the image above show the effects of shearing on the selected vertices when the pivot point is altered. In middle frame, the Pivot Point is set to Median Point and the mouse was moved to the left during the transform. In right frame, the Pivot Point is set to the 3D cursor which is located above the mesh. When the mouse is moved to the left during a Shear transform, the selected vertices are moved to the right as they are below the horizontal axis.

Tip

切变变换程度

The magnitude of the Shear transform applied to the selected elements is directly proportional to the distance from the horizontal axis. i.e. the further it is away from the axis, the greater the movement.
