Axis Locking

Axis locking.

This pick limits the transformation to the specified axis.

Transformations (translation/scale/rotation) in Object Mode and Edit Mode (as well as extrusions in Edit Manner) can be locked to a particular axis relative to the current transform orientation. By locking a transformation to a particular centrality yous are restricting transformations to a unmarried dimension.

Usage

A locked centrality will brandish in a brighter color than an unlocked axis. For example in the paradigm to the correct, the Z axis is shown in light blueish equally movement is constrained to this axis. This example, tin can be achieved in two ways:

Hotkey

The axis of motility tin can exist changed at any time during transformation past typing 10, Y, Z.

Pointing

Axis constraint in activity.

Holding MMB after starting a transformation lets y'all select an axis to constrain to. A visual option to constrain the translation will be available, showing the three axes in the 3D Viewport space. A dotted white line is used as a pointer. The axis of choice to ostend the operation will depend on the highlighted axis about which the MMB is released.

When y'all already moved the mouse in the desired direction, pressing MMB will lock to the centrality which was pointed at.

Axis locking limits the transformation to a single axis (or forbids transformations along 2 axes). An object, face, vertex or other selectable particular will only be able to move, calibration or rotate in a unmarried dimension.

Aeroplane locking.

Plane locking locks the transformation to two axes (or forbids transformations along ane centrality), thus creating a plane in which the element tin can be moved or scaled freely. Plane locking simply affects translation and scaling.

Note that for rotation, both axis and plane locking take the same effect because a rotation is always constrained around one centrality. Trackball type rotations R R cannot exist locked at all.

Axis Locking Modes

A single primal press constrains movement to the current transform orientation pick. A second central press of the same central constrains motion to the respective Global axis (except if the transform orientation is set to Global, in which case the Local orientation is used). A third key press of the same key removes constraints.

The orientation can be set in the Transform Orientation selector of the 3D Viewport header.

For example, if the current transform orientation is set to Normal, pressing 1000 to beginning translation, followed by Z will lock translation in the Z direction relative to the Normal orientation, pressing Z again volition lock translation to the Z axis relative to the Global orientation. Pressing Z again will remove all constraints. The electric current mode volition exist displayed in the left-hand side of the 3D Viewport header.

As can be seen in the Axis locking modes image, the direction of the transform as well takes into business relationship the selection.

Notation that using a locked axis does not foreclose you lot from using the keyboard to enter numeric transformation values.
