Don't try to be perfect, it will never work. You have to remember that the studio model was wacky to begin with. There was nothing a symetrical about it at all and to be quite honest in the cg world you'll never really see that anyways.
For one i quit trying to be accurate with parts of the ship since by the time you get close to finishing it it will already be a resource hog.
Those lines won't make a bit of difference.
