Opening .iam files on AutoCad WS for IPad

[RogerHebert]

Wondering what is the proper way to get the Inventor file (from a PC) to the AutoCad WS Program on my IPad (sync'd of course to a MAC). There's no Inventor Program for MAC, so I've tried opening the program in AutoCad for Mac, and then converting it to the .dwg format required (I think) for AutoCad WS. No luck.

I also tried to drag the .iam file to the desktop, hoping I could open it (via ITunes) in AutoCad WS, but no luck either.

Possibly Inventor files can't be displayed in Autocad WS?

Question 2: is there an Autodesk Inventor version for MAC upcoming? That would be awesome...
