You can use the 3D tool to place a 3D file (in U3D 3rd Edition or PRC format) on a PDF page. Acrobat Pro can create 3D PDFs but only from U3D ECMA 1 files.
After you place a 3D file, you can adjust the area or canvas in which the 3D model appears, edit the presentation properties for the 3D toolbar and content, and create additional views.
In the Insert 3D dialog box, check the Show Advanced Options to set initial 3D Properties for the file.
View 3D properties by using the Select Object Tool (Tools > Interactive Objects > Select Object) to double-click within an activated model.
The options on the 3D tab determine how the 3D model is presented. Unlike the settings on the other tabs, 3D settings do not affect the imported file itself.
The options on the 3D tab are the same as the options on the 3D toolbar except for the following:
For models created with animation, this setting determines how the animation runs in Acrobat.
Add Default Views
Allows you to use different model views. An orthographic projection (ortho) effectively removes a dimension, preserving the size ratio between objects but giving the 3D model a less realistic appearance. Orthographic projection is especially useful for viewing certain diagrams, such as 3D mathematical functions plotted on a graph. A perspective projection offers a more realistic scene in which objects in the distance appear smaller than objects of the same size in the foreground.
Displays the 3D toolbar along with the image. When this option is not selected, you can right-click the 3D image to view the 3D toolbar.
Open model tree
Displays the model tree on the Model Tree pane. The Model Tree has three panes. Each pane displays a specific type of information or controls.
Specifies when the 3D model is activated. When the 3D model is enabled, you can interact with it by using the 3D navigation tools, for example.
Determines how the 3D model can be deactivated. When a 3D model is disabled, the 2D preview image or poster appears in the canvas.
Enables you to display the 3D model in a floating window outside the page. If you select Play Content In Floating Window, you can select the size of the window (in pixels) from the Height and Width menus.
To replace the default view of the 3D model when it isn’t activated, select a poster image option. Click Browse to find the image you want.
Use the Resources tab to add files developed in Flash® to a 3D model for animation, effects, and textures. To bind a Flash resource, select it from the list of resources, and then select a binding type (Foreground, Background, or Material). To bind a material, also enter the material name for the part or parts where you want to display the material.
Displays the name of the file that is selected from the list. You can also rename a resource, which is useful with scripting. For example, you can replace the name with the one used in a script.
When adding files that are developed in Flash as a resource for a 3D model, binding determines how those files interact. For example, you can identify a resource to run in the background and one to run in the foreground. After you add the files to the file list, select one, and in the Binding section, select either Background, Foreground, or Material.
3D designers can use the Material field to define a material to use in a model. The material name can be associated with a resource by selecting Material in the Binding section.
Flash developers can use the FlashVars field to add ActionScript™ variables for the selected file.
