Adding 3D tracks

If you have QuickDraw 3D files, you can import them in the 3D track. Drag the 3D track icon from the QuickTime tab on the Objects palette into the track list area of the TimeLine Window. Navigate and choose the QuickDraw 3D file. You'll see the 3D track in the track content area and the 3D Track Inspector. Set the properties as necessary.
