Shearing deforms the selected geometry by moving the vertices above the Pivot Point to the left and the vertices below that point to the right (or vice versa). The higher or lower a vertex is compared to the pivot point, the further it will be moved. The result is that vertical edges become diagonal while horizontal edges stay the same.
Cách Dùng [Usage]¶
Công Cụ (Tool)¶
Set up a pivot point and optionally a transform orientation. Pick an axis on the gizmo that matches the desired "above"/"below" direction (which determines how much each vertex should be sheared). Finally, drag the handle that matches the desired "horizontal" direction (in which the vertices should be moved).
Using the Shear tool.¶
Operator (Thao Tác)¶
Set up a pivot point, then either click the menu item or press the keyboard shortcut. Move the mouse left or right to shear, then click LMB to confirm.
By default, the meanings of "above," "below," and "horizontal" are all in the current viewing plane in the 3D Viewport, but this can be changed in the options.
Using the Shear operator with different pivot points.¶
Các Tùy Chọn (Options)¶
- Góc Độ (Angle)
How much to "rotate" the vertical edges.
- Axis (Trục)
The axis that's perpendicular to the shearing plane. For example, if the vertices should move along the X axis and their distance from the pivot point should be measured along the Y axis, the Axis should be set to Z.
- Axis Ortho
The axis along which the vertices should move. This must be different from Axis.
- Định Hướng (Orientation)
The Transform Orientation from which to pick the Axis and Axis Ortho.
- Biên Soạn Phản Chiếu Đối Xứng (Mirror Editing)
Whether to also affect matching geometry on the other side of the mesh. Mesh Symmetry needs to be enabled for this to work.
