Transform Modal Map#

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).

Constraints#

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.

Snapping#

Transform operations use the snapping settings set in the scene. However, some options can be changed during the transformation.

Snap Invert#

Even if the magnetic icon is disabled, you can still enable snapping during a transformation. The default hotkey in this case is Ctrl.

Set Snap Base#

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.

Add Snap Point#

While you’re transforming a selection with snapping enabled, you can press A whenever there’s a highlighted snap target to mark it. With multiple such targets marked, the selection will then be snapped to their average location.

Marking a target more than once will give it more weight.
