USING ACROBAT 9 PRO 387 Multimedia and 3D models Open Model Tree On 3D Activation Determines whether the Model Tree is displayed when the 3D model is activated. Choose Use Annotation's Setting to use whichever setting the author used when adding the 3D model to the PDF. Default Toolbar State Determines whether the 3D toolbar is shown or hidden when a 3D model is activated. Choose Use Annotation's Setting to use whichever setting the author used when adding the 3D model to the PDF. Enable Selection For The Hand Tool Lets the user select and highlight parts of the 3D model using the Hand tool. If this option is not selected, use the Object Data tool (Tools > Analysis > Object Data Tool) to select the object. Consolidate Tools On The 3D Toolbar Selecting this option places the manipulation and navigation tools under the Rotate tool, thereby shortening the 3D toolbar. Enable View Transitions Some 3D models include animated transitions between views. Deselect this option if you want to prevent this 3D animation. Show 3D Orientation Axis Turns on or off an in-scene display of an axis that indicates the current orientation of the 3D scene. Optimization Scheme For Low Framerate Specifies what happens to animations of complex models when the framerate becomes low. None does not compromise the visuals and leaves the framerate low. Bounding Box shows the three-dimensional planes enclosing the parts instead of the parts themselves, which keeps the framerate high. Drop Objects does not show some parts of the model, which keeps the framerate high. Framerate Threshold Sets the minimum framerate, either by dragging the slider or entering a number in the value box. If the framerate drops below that number of frames per second, the Optimization Scheme For Low Framerate option goes into effect. Comment on 3D designs Comments added to a 3D object are associated with specific views that are defined when the comments are added. If the view is changed-for example, if the 3D object is rotated or moved-the comments are no longer visible. You have three ways to add comments to a 3D object: • Using the 3D Comment Tool on the 3D toolbar to add comments to specific parts of a 3D model. • Using the Comments and Markup toolbar to add a variety of comment types to a 3D view. • Converting a 3D measurement into a comment. Note: Adding comments to 3D model views requires version 7.0.7 or later of Acrobat or Reader. When the view of a 3D object is changed, any comment associated with that object disappears (right).
