I tried from pro engineer into AC14 and its very flakey to say the least. I was hoping that by now they would have managed to join engineering components to architectural. I have had this problem for years and solved it only by using 3D studio but its not a very elegant solution. Has anyone tried it with AC15 yet?

The best way I found was Pro-eng out as stl, open in blender and correct the orientation, then save as 3D-studio. Import this into AC.
Hope this helps.
