Hi Mark,
I'd recommend RDV for this - check out www.rdvsystems.com
They have samples for viewing online and trial downloads available to see how easy and practical the software is.
cheers,

Thanks for the information. Can you send out any help concerning rendering time and motion path animations. We are trying to implement the option as a marketing tool here but have found the process to be painfully slow. We do have the Autodesk required system configuration, although I feel it is the minimum.
