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 Blender Preferences ‣ Keymap ‣ Transform Modal Map (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

The Snap Base is automatically determined based on the Snap Base options. However, this automatic snap detection point of origin may not always align with the user’s intentions. Therefore, transform operations include a utility to set a new snap origin point during the transformation. The new Snap Base will correspond to the snap point whose target is defined by the Snap Target.

默认快捷键是 B。

Note

If only Snap to Increment is enabled as Snap Target, the targets Vertex, Edge, Face and Edge Center will be used instead.

添加吸附点

当您在启用吸附后变换选中项时，只要有突出显示的吸附目标标记，就可以按 A。标记了多个目标后，选中项将被吸附到其平均位置。

多次标记目标会赋予其更大的权重。

导航

While performing a modal transformation, you can perform navigation actions such as zooming, panning, or rotating by holding Alt then perform the desired action.
