| iTool User's Guide: Working with Volumes |

## Adding Axes

By default, volumes are displayed with X, Y, and Z axes. The display of these axes is controlled by property sheets for the axes container and for individual axes (see Axes). Additional X, Y, or Z axes can be added to a volume visualization to make it easier to identify volume characteristics.

To add an axis to your volume visualization:

1. Select the volume.

2. Select Insert Axis.

3. Choose from the following options:

- X axis

- Y axis

- Z axis

Use the mouse to position the new axis and double-click the axis to display the axis property sheet.

For more information on adding axes, see Additional Axes.
