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.

Axis modes

Axis modes specify on which set of axes a 3D layer is transformed. Choose a mode in the Tools panel.

Local Axis mode Aligns the axes to the surface of a 3D layer.

World Axis mode 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.

View Axis mode Alignstheaxestotheviewyouhaveselected.Forexample,supposethatalayerhasbeenrotated

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.

Note: The camera tools always adjust along the view’s local axes, so the action of the camera tools is not affected by the

axis modes.
