Click Add to specify a player and the settings that are required, preferred, or disallowed to play the
movie clip. Select the name of the player, the minimum version number of the player, and the status. If you set the
status of more than one player to Required, only one of the required players may be used to play the rendition. If you
set the status of players to Preferred, these players are selected over nonpreferred players (but not over required
players). If you set the status of players to Disallowed, they are not used to play the rendition.
Playback Location
Use this tab todetermine whether a movie clip is played in the PDF, remains hidden while played
(recommended for sound clips), is played in a floating window, or is played full screen. When Floating Window is
selected, you can add a title, set the window position, and let the user resize or close the window. Note that the user’s
preference settings may require (or ignore) title bar text for playback.
The window position is determined relative to the document window, application window, or, for dual-monitor
configurations, the virtual desktop or primary desktop. You may also specify the width and height of the floating
window. Click Get From Media to obtain the movie clip’s dimensions, if available, and then edit as necessary.
System Requirements
Use this tab to choose the minimum settings for systems on which the movie clip is played.
For example, you can require that a user have at least a 1024-by-768 screen resolution to play the movie clip. For
options such as Play Dubbed Audio, you can select Either, Disabled, or Enabled. If you select Either, you defer to the
settings in the user’s Multimedia panel of the Preferences dialog box. If you select Disabled or Enabled, the corre
sponding setting in Multimedia preferences must allow the rendition to be used. For example, if the Play Dubbed
Audio option is enabled, the rendition may be used only if the Play Dubbed Audio preference option is selected.
Playback Requirements
Use this tab to select which attributes are required for the rendition to be played. The
attributes on this tab include settings from the other tabs, letting you indicate which ones are required. For example,
if you set the volume to 50% in the Playback Requirements tab, and you don’t want the rendition to be played unless
this volume level can be used, select the Required box next to Volume.

The Model Tree has three panes, each of which displays a specific type of information or controls.
Structure pane
The topmost pane shows the tree structure of the 3D object. For example, a 3D object depicting a
car may have separate groups of objects (called nodes) for the chassis, engine, and wheels. In this pane, you can move
through the hierarchy and select, isolate, or hide various parts.
Product Manufacturing Information (PMI) appears as a group of items on the same hierarchical level as its related
object or assembly.
View pane
The middle pane lists the defined views, which you can add to and edit. For example, after you isolate
and rotate a part, you can save that particular view. After making other transformations, you can simply click the
view you created to return the 3D model to the view that you saved earlier. See “Set 3D views” on page 397.
Object Data pane
The lower pane displays other information, including properties and metadata, if any, about the
object or part. You cannot edit this information for 3D objects in Acrobat.

Changes the center focus from the entire 3D model to the selected parts. This setting is especially
useful for rotating a part, allowing the rotation to occur around the part’s center focus rather than that of the entire
model.
Transparent
Displays a see-through version of the selected part.
Export As XML
Creates a separate XML file of either Whole Tree or Current Node of the 3D model.
Note:
If the 3D model was created to include Product Manufacturing Information (PMI), options for showing and hiding
the PMI may be available on this menu.
