## Showing an Image Plane

An image plane is a visualization of a slice of the volume. An image plane can be dragged and rotated within the volume. To show an image plane for a portion of volume data, first be sure your volume is selected and then choose Operations Volume Image Plane. An image plane appears showing a cross-section of your volume data. You can change the orientation of an image plane by double-clicking on the image plane to bring up the property browser. You can also click on the edge of the plane and move it to various other points in the volume data.
