Lăn Xương (Bone Roll)¶
The bone roll is a part of a bone's rest pose defining its default rotation around the bone's length. You can control the bone roll in Edit Mode.

Shift-N
Automatically align the roll of all selected bones to various points of reference.
- Định Hướng của Trục [Axis Orientation]
- Local (X, Z, -X, -Z) Tangent
Align the roll of the selected bones relative to the axis defined by the bones and their parent. If a bone has no parent, use the first child as a point of reference instead, even if that child is not connected and another one is. For bones with no parent and no children, this option does nothing.
- Global (X, Y, Z, -X, -Y, -Z) Axis
Align the roll of the selected bones such that their Z axis points towards the chosen global axis.
- Xương đang Hoạt Động (Active Bone)
Align the roll of the selected bones such that their Z axis points where the active bone's Z axis is currently pointing.
- Trục của Góc Nhìn (View Axis)
Align the roll of the selected bones such that their Z axis points at the viewport's forward/backward axis, basically the user's eyes.
- Con Trỏ (Cursor)
Align the roll of the selected bones such that their Z axis points at the 3D cursor.
- Lật Trục (Flip Axis)
Change the result by 180°.
- Xoay Chiều Ngắn Nhất (Shortest Rotation)
Change the result by 180° when needed in order to force the absolute roll value below 90°. For example, for an initial result of 160°, this option will instead flip that to -20°.
