Convert a 3D file to PDF with code

Hello,

I would like to create a program which converts 3d files to PDF 3D.

I am really flexible. It can be with any version of Adobe Acrobat program, and in any language.

The point is that I wouldn't need to open the 3d file with the Adobe Acrobat Reader, and save it as PDF.

All has to be Automatically!

Thank you!!!
