How do I use Inventor work in Blender

I work for an engineering firm who has extensive Inventor drawings that I would like to animate beyond the capabilities of the Inventor animation options. Can I open the original Inventor file in Blender? I’ve been told the dxf file that Blender can import does not contain 3d information and from what I can tell I cannot import .ipt or .iam files. As you can probably tell I’m VERY green in this area and Maya and 3ds max are just out of my price range.
Help Please!

Sorry. New to these forums. The Other Programs forum seemed more appropriate for this question.
