Embedding 3D Objects in your PDF
To add 3D files to your PDFs use the 3D Tool
Click in the Advanced toolbar.
Select an area on the page for the insertion of the 3D object.
Browse to the u3d file you want to embed and select it.
PDF Professional works with 3D files in the *.u3d format. This is a universal file format for 3D file content description.
If a document with 3D objects is flattened, they become simple two-dimensional document objects.
