This past week Autodesk has released a new technology preview add-in for Autodesk Inventor on their "Labs" site. This new add-in will allow you to import Parasolid verion 9-18 files and UG-NX version 3 & 4 files into Autodesk Inventor. This new add-in is only for Autodesk Inventor 2008. Basically this allows you to import these files as dump solids without features almost like a STEP file. The good part is you don't need to create the STEP file. I think this is a well needed feature for some users and glad Autodesk as able to come out with this. You can downloaded the add-in at the Autodesk labs website
Also if you need to import or export other file formats that are not included the TransMagic product works great. (www.transmagic.com)
