Overview

Sceneri by default features a world coordinate system where the Z-Axis points upwards.

When manipulating objects directly with the Axis Gizmo, you can change the coordinate system to help you with the manipulation.

You can change the coordinate system directly from the Coordinates toolbar:

World Coordinates

Uses the world’s axis orientation for translation/rotation/scaling. The Axis Gizmo always stays aligned with the world coordinate system.

Local Coordinates

Uses the selected object’s original pivot orientation for translation/rotation/scaling.
In the picture below, only the cube has been rotated. Note how the axes are aligned to the cube.
