Pro/E to UG-NX4

Hi,

has anyone cracked a reliable way to transfer data between pro/eWF2(3?) and NX4? Using parasolid between solidworks and NX is a dream, but STEP between Pro and NX has given me so many headaches… I’m now embarking on a major project where this will be a necessary part of my workflow and I need to find a reliable solution… anyone have good experience with this and any rules regarding settings.

thanks guys
