How do I create U3d Files?

Is it possible to create u3d files within Acrobat3D?

I would like to include 3D elements in my PDF training documentation. I have
looked into this a little and it seems the only 3D application that export
(converts) to u3d is Right Hemisphere. Is this correct and does this mean I need
to spend $500 to do this?

It seems a little weak.

Hi Nick,

You don't have to have a U3D file to create 3D PDF. There are many supported 3D
file types. U3D is just one of them. For a list of supported file types, go to:

Hi Thanks for the reply.

Sorry for the lame post. I have just done a test with a .obj and imports no
problem. That will teach me to take someone else's word for it.
