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 (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.
