Yes, I saw the effect on split edge in realtime playing a little with it. I used 20° but I modified it to 10° to eliminate any possible difference between my and your tests.
I would prefer not to modify anything in Blender, the projects starts in pro/e, but you're right.
Here you can find my export setup. Note: this is an old pro/e version, the real job has to be done on wildfire5. Dunno if it matters.
