变换模态映射
During a transformation, some hotkeys can change the behavior of the operation.
You can check editing the keys of these modal modifiers in (at the bottom of the keymap).
约束
When moving, rotating or scaling, if you only want certain axes to be affected, you can restrict the transformation to those axes.
By default the constraint keys are X, Y and Z. This constraint can be restricted to plane if :kbd`Shift` is pressed or automatically detected if MMB is pressed.
It is worth noting that if you press the same contraint hotkey a second time, you change the orientation from Local to Global or vice versa. Pressing a third time disables the constraint.
吸附
Transform operations use the snapping settings set in the scene. However, some options can be changed during the transformation.
吸附反转
Even if the magnetic icon is disabled, you can still enable snapping during a transformation. The default hotkey in this case is Ctrl.
设置吸附基准
Snap Base is taken automatically depending on the Snap With options. However, this automatic snap detection point of origin is not always what the user desires. Therefore, transform operations have a utility to set a new snap origin point during the transformation. By default the hotkey is B.
添加吸附点
当您在启用捕捉时转换选择时，只要有突出显示的捕捉目标标记，就可以按 A 。标记了多个此类目标后，选择将被捕获到其平均位置。
多次标记目标会赋予其更大的权重。
多个吸附目标。
