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.
Tool Settings¶
- Offset
- How far items are shifted from their original location.
- Shear Axis
- The shear tool shears items along a 2D plane. The Shear Axis controls whether the items are sheared along the X or Y axes of this imaginary plane. The orientation of this plane is controlled by the following two axis controls.
- Axis
- Defines one axis of the imaginary shearing plane.
- Axis Ortho
- Defines the other axis of the imaginary shearing plane.
- Orientation
- See Transform Orientations.
- Proportional Editing
- See Proportional Editing.
Warning
The Axis and Axis Ortho cannot be the same axis, else the imaginary plane is dimensionless and the objects will disappear into a point.
用法¶
See below for the result of using Shear on a number of different elements.
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
选中元素 切变 变换的程度正比于到水平轴线的距离,也就是说,离轴线越远,移动量越大。
