World, Object, Root, Parent
The world axes, the object’s axes, the axes of the object that is at the root of the hierarchy, and the
axes of the object’s immediate parent respectively.
Normal
The average direction of the normals of the selected polygons (the modeling axis points with its Z-
axis).
Camera
The camera.
Retain Changes
If this option is enabled, the modeling axis will temporarily retain its position after being moved or
rotated. For example, suppose Axis is set to Object (in this mode, the modeling axis will be positioned
at the object’s origin). You select some polygons and move them to a new position by dragging an axis
arrowhead. The modeling axis will move along with the polygons while you are dragging the polygons
to their new position. If Retain Changes is enabled, the modeling axis will stay where it is when you
release the mouse button. If the option is disabled, the modeling axis will immediately jump back to
the object’s origin as soon as you release the mouse button.
Along Normals
If this option is enabled, selected points, edges and polygons will be scaled or rotated along the
average direction of their normals.
Object
If Axis is set to Object, you can drag and drop any object from the Object manager into this box. The
modeling axis will then be positioned at this object’s origin (and will also point in the same direction
as this object’s axis system if Orientation is set to Object).
X, Y, Z
These sliders enable you to offset the modeling axis in the Selected and Bounds modes.
