Converting 3D models

About supported 3D file formats

Acrobat 3D can utilize a variety of file formats, including many types of 3D models. A list of the supported file

formats appears in the Preferences dialog box (Edit > Preferences, and select Convert To PDF under Categories). You

can bring supported file formats directly into PDFs using the following methods.

Converting Uses 3D files to create PDFs that have one or more pages. This method retains the original file structure,

including part names and hierarchies.

Inserting Brings a 3D file into an existing PDF as a new page.

Adding with the 3D tool Places a 3D model on an existing page of a PDF.

Converting gives you the most options for representing the 3D model and preserves the original file’s structure. For

example, you can reduce the number of polygons, remove small objects and duplicate parts, and decrease the overall

file size. Relationships between parts, subparts, and assemblies look the same as in the original 3D file.

save it in a supported format, such as U3D or RH.

If a 3D model is in a format that Acrobat 3D and Acrobat 3D Toolkit don’t support, and you have access to the

original application that created the 3D model, you can open the file in that application and capture it. Capturing

does not preserve the file structure of 3D models but lists all parts under a single assembly.

Convert 3D files into PDFs

You can convert 3D and CAD files in supported formats to PDFs that have one or more pages. The default preset

works best for most types of conversion; however, you can change these settings or select a different preset during

conversion. (To view 3D conversion settings before you convert a file, choose Edit > Preferences, select Convert To

PDF on the left, select a file format, and click Settings.)

3D files are converted as either PRC or U3D data streams and then stored in the resulting PDF file. The file format

of the 3D file determines whether PRC or U3D settings (or both) are available in the Acrobat 3D Conversion dialog

box, and it determines which entities you can import to the PDF.

If your Windows computer uses an integrated video card, upgrade your video card driver to help ensure that the 3D

content renders correctly. You can get the latest driver from the video card or computer manufacturer.
