Transform Orientations

Reference

Mode: Object and Edit Modes
Panel: Header ‣ Transform Orientations
Shortcut: Comma

Transform Orientations affect the behavior of Transformations. You will see an effect on the Object Gizmo (the widget in the center of the selection), as well as on transformation constraints, Axis Locking.

For example, when you press X, during the execution of the operation, it will constrain the transformation to the Global X axis. But if you press X a second time it will constrain to your Transform Orientation's X axis.

The Orientations options can be set through the Transform Orientation selector in a 3D Viewport header.

In addition to the five preset options, you can define your own custom orientation (see Custom Orientations below).

Orientations

Global

Align the transformation axes to world space.

The Navigation Gizmo in the top right corner of the viewport, and the Grid Floor, shows the axes of world coordinate system.

Local

Align the transformation axes to the selected objects' space.

When an object is rotated, the direction of the Local gizmo matches to the object's rotation relative to the global axes. While the Global gizmo always correspond to world coordinates.

Normal

Align the transformation axes so that the Z axis of the gizmo will match the average Normal of the selected element. If multiple elements are selected, it will orient towards the average of those normals.

In Object Mode, this is equivalent to Local orientation.

Gimbal

Align each axis to the Euler rotation axis as used for input. Uses a Gimbal behavior that can be changed depending on the current Rotation Mode.

View

Align the transformation axes to the window of the 3D Viewport:

Y: Up/Down
X: Left/Right
Z: Towards/Away from the screen

Cursor

Align the transformation axes to the 3D cursor.

Custom Orientations

Reference

Mode: Object and Edit Modes
Panel: Header ‣ Transform Orientations

You can define custom transform orientations, using object or mesh elements. Custom transform orientations defined from objects use the Local orientation of the object whereas those defined from selected mesh elements (vertices, edges, faces) use the Normal orientation of the selection.

../../../_images/editors_3dview_controls_orientation_custom.png — Transform Orientations panel.

The Transform Orientations panel, found in the header of the 3D Viewport, can be used to manage transform orientations: selecting the active orientation, adding ("+" icon), deleting ("X" icon) and rename custom orientations.

The default name for these orientations is derived from what you have selected. If it's an edge, it will be titled, "Edge", if it's an object, it will take that object's name, etc.

Create Orientation

To create a custom orientation, select the object or mesh element(s) and click the "+" button on the Transform Orientations panel.

../../../_images/editors_3dview_controls_orientation_custom-name.png — Create Orientation Adjust Last Operation panel.

Just after creating the orientation, the Create Orientation Adjust Last Operation panel gives a few options:

Name: Text field for naming the new orientation.
Use View: The new orientation will be aligned to the view space.
Use After Creation: If checked it leaves the newly created orientation active.
Overwrite Previous: If the new orientation is given an existing name, a suffix will be added to it to avoid overwriting the old one, unless Overwrite Previous is checked, in which case it will be overwritten.
