To export 3D geometry to a U3D file, use the File > Export > Visualization File Types > U3D menu item. You can then use the U3D file with Adobe Acrobat to create your own 3D annotations.

When the product generates a U3D file, it also generates a JavaScript file with the same name but with a ".js" extension. This file contains additional information and JavaScript code to enhance the behavior of the 3D Annotation within Acrobat. It includes code to control animations and additional tools to control geometry display.
