You can add axes to a 3D scene and parent them to cameras, lights, layers, and other axes in the Group Schematic. This lets you control the movement of one or more child objects by transforming the parent axis.

You can transform axes interactively using the transformation buttons in the Axes tab, where you can also set values for the axis position, rotation, scale, and pivot. You can animate and set expressions for all transformation values, as well as assign them to a tracker. The axis is represented by a white cross in the Player, which you can select and interactively move with the manipulator.

To add an axis from the Axes tab:

1. In the Schematic view, select the Reaction node and then select the Axes tab.
2. From the Axes list, click Add.

   An axis is added to the Axes list.

3. In the Schematic view, double-click the Reaction node to display the Group Schematic.
4. Parent the axis to a layer, camera, or light.

To add an axis from the Tools tab:

1. In the Schematic view, double-click the Reaction node to display the Group Schematic.
2. From the Tools tab, drag the Axis tool from the Reaction folder to the Group Schematic.
3. In the Schematic view, parent the axis to a layer, camera, or light.

To set the visibility of an axis:

1. In the Schematic view, select the Reaction node.
