Help! sanity check needed

Hello everyone; can someone please save my mind because I don't understand why the final geometries of these 2 parts are different.  Attached is the assembly of experiment5.prt (gray) and 01659_experiment6.prt (purple).  They have the same feature tree, because the latter is a copy of the former.

FYI, I edited the definition of some sweeps in the copy as I was trying to learn the modeling technique.  I don't think I made any changes, but clearly something is different.

I'm using Creo 2.0 M160.

I haven't opened your files, but have you done a compare part by geometry to verify that they are actually different and its not just a graphics issue?

for the graphic side, you may also try changing your shade quality from default 3 to 10

file > options > model display > set shade quality to: <10>

Brilliant!  Thanks Matt!  It seems so obvious when you highlight it like this

I see that I did mess up the sweep cross-section.  In the copy, the coincident constraint on the inner trajectory, whereas in the original, it is on the outer trajectory.

I suppose I still don't understand why that makes the difference for I thought these trajectory points are "horizontal" anyway...

Thank you everyone for your help.
