Creating PDF documents with 3D models
You can add a 3D model to an Adobe PDF document by importing it from a 3D CAD file
or by capturing it from a 3D CAD application. One advantage to creating a PDF document
from a 3D file is that the 3D model's file structure, including part names and hierarchy, is
preserved. You can also add 3D models to PDF documents using the 3D Tool. If the 3D
CAD file is unavailable or unsupported, you can capture the file from its 3D CAD
application. During capture, a 3D model's file structure is not preserved.
When you import or capture a 3D model, you can specify settings to determine how the
3D model is converted. For example, you can decrease the file size by reducing the
number of polygons and removing small objects and duplicate parts. For increased
interactivity with the 3D model, you can include a JavaScript (JS) file. For example, you
can add custom menus, tools, and animation.
If your Windows computer uses an integrated video card, upgrade your video card driver
to help ensure that the 3D content will render correctly. You can get the latest driver from
your video card or laptop manufacturer.
To view a list of supported 3D CAD formats, choose Edit > Preferences, and then
click Convert To PDF to display the list of supported file types and extensions. If you
need to import or capture a 3D CAD format not supported by Acrobat 3D, try opening the
file in Acrobat 3D Toolkit, which supports additional formats.
