When PDF files include 3D models,
viewers using Adobe Reader or Adobe Acrobat can interact with the
3D models using built-in features such as zoom, pan, and rotation
tools. Creating PDF files with 3D models requires Acrobat 3D, which
supports a variety of 3D file formats.
Note: Acrobat Professional
can create 3D PDFs but only from .u3d version 1.0 files.
