software to convert Inventor models into 3d pdf's

Is there specific "free" software that can be obtained that would enable me to take one of my existing models and create a rotating model in a pdf so that a customer can view it?

i mention it as free as I am sure it has come up in converstaion with someone during the last year...but i am guessing that it is the viewer that would be free...I would imagine that I would need something like Adobe 3D design software to create the the document. This isnt a problem, just did not want design specific software.

i am wondering if there are programs available that would enable me to pack my model up...and e-mail it with a program that would enable the customer to view the model, and also not see dimensions within the parts.

thanks.

Don't use PDF use DWF...its free and a part of Inventor already. The viewer is also free and allows you to do so much more than the Adobe 3D.

Thanks...appreciated.

Very handy that free viewer, I have told a few suppliers and customers about it and they get on great with it.
