Once you enable the 3D Option, the 3D Rotate tool becomes available. A rotation sphere appear will around the pivot points to indicate the different axes.
You can click on the direction ellipses to rotate your layer on one axis only. If you click anywhere else, the layer rotates freely on two axes at once. Once the ellipse is selected, it will turn pink.
If you move the layers in the
Perspective view, it may be difficult to control the motion since you may not have the optimum point of view on your
stage to understand the setup. In this case it is best to use the direction ellipses.
