Opens the color picker, which you can use to select a different color for the space surrounding the 3D object.
Toggle Cross Section
Shows and hides cross sections of the object. Click the pop-up menu to open the Cross Section Properties dialog box.
For more information, see
Create cross sections .
Add Multimedia/3D Comment
Enables you to add a sticky note to any part of the 3D model. The note stays with the view. See Commenting on 3D
designs in PDFs .
3D preferences
In the 3D & Multimedia panel of the Preferences dialog box, you can determine whether the 3D toolbar and Model
Tree are displayed by default. You can also specify a default renderer and determine whether animations are allowed.
Preferred Renderer Specifies the rendering engine used to affect both performance and quality, so it’s important to
select the appropriate renderer. Depending on your system, you can change your render engine. If you select a DirectX®
or OpenGL option, all rendering takes place using the graphics chip on the video adapter. If Software is selected,
rendering takes more time, but the performance is often more consistent with the model rendering of the originating
application.
Enable Hardware Rendering For Legacy Video Cards Forces the use of a hardware accelerator for even video adapters
that do not support a pixel shader.
Enable Double-Sided Rendering Some model parts have two sides. To save time and space, you can deselect this option
to render only the side facing the user. If the user looks inside a part rendered with only one side, the back side would
be invisible.
Preferred 3D PMI Rendering Mode Specifies the PMI mode to use for rendering. You can select one of the following
options:
Use Content Setting—The rendering of the PMI uses the setting of each PMI to decide whether it uses the Z-buffer.
Always Render 3D PMI In Front Of Model—The rendering of the PMI ignores the Z-buffer regardless of the setting in
the file.
Always Render 3D PMI Using Z-buffer—The rendering of the PMI always turns on Z-buffer regardless of the setting
in the file.
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 > Interactive Objects > Select Object) 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.
