Rotate or orient a 3D layer
You can turn a 3D layer by changing its Orientation or Rotation values. In both cases, the layer turns around its anchor point. The Orientation and
Rotation properties differ in how the layer moves when you animate them.
When you animate the Orientation property of a 3D layer, the layer turns as directly as possible to reach the specified orientation. When you
animate any of the X, Y, or Z Rotation properties, the layer rotates along each individual axis according to the individual property values. In other
words, Orientation values specify an angular destination, whereas Rotation values specify an angular route. Animate Rotation properties to make a
layer turn multiple times.
Animating the Orientation property is often better for natural, smooth motion, whereas animating the Rotation properties provides more precise
control.
Rotate or orient a 3D layer in the Composition panel
1. Select the 3D layer that you want to turn.
2. Select the Rotation tool , and choose Orientation or Rotation from the Set menu to determine whether the tool affects Orientation or
Rotation properties.
3. In the Composition panel, do one of the following:
Drag the arrowhead of the 3D axis layer control corresponding to the axis around which you want to turn the layer.
Drag a layer handle. Dragging a corner handle turns the layer around the z axis; dragging a left or right center handle turns the layer
around the y axis; dragging a top or bottom handle turns the layer around the x axis.
Drag the layer.
Shift-drag to constrain your manipulations to 45-degree increments.
Rotate or orient a 3D layer in the Timeline panel
1. Select the 3D layer that you want to turn.
2. In the Timeline panel, modify the Rotation or Orientation property values.
Press R to show Rotation and Orientation properties.
Online resources about rotating and orienting 3D layers
Donat Van Bellinghen provides some expressions on the AE Enhancers forum for placing and orienting a 3D layer in the plane defined by three
points.

Axis modes
Axis modes specify on which set of axes a 3D layer is transformed. Choose a mode in the Tools panel.
Aligns the axes to the surface of a 3D layer.
Aligns the axes to the absolute coordinates of the composition. Regardless of the rotations you perform on a layer, the axes
always represent 3D space relative to the 3D world.
Aligns the axes to the view you have selected. For example, suppose that a layer has been rotated and the view changed to
a custom view; any subsequent transformation made to that layer while in View Axis mode happens along the axes corresponding to the direction
from which you are looking at the layer.
Differences between the axis modes are only relevant when you have a 3D camera in a composition.
The Camera tools always adjust along the local axes of the view, so the action of the Camera tools is not affected by the axis modes.
