Asks the user whether the player can be used. If you select this option and allow the player to play the
media in a particular document, that document becomes trusted.

prevent media from playing in documents that were previously trusted documents or created by trusted authors.
This option is available only when a PDF that contains multimedia is open.
Interacting with 3D models
Displaying 3D models
In Acrobat, you can view and interact with high-quality 3D content created in professional 3D CAD or 3D modeling
programs and embedded in PDFs. For example, you can selectively hide and show parts of a 3D model, remove a
cover to look inside, and turn parts around as if holding them in your hands.
3D content may initially appear as a two-dimensional preview image. Clicking the 3D model with the Hand or Select
tool enables (or activates) the model, opens the 3D toolbar, and plays any animation.
