Easier said than done...if you don't know it's called paneling then you wouldn't know what to search for.
I just zoom in tight as possible in my design software, cut that artwork right in half, plot it as two seperate pieces and overlap it. I'm sure it's not the proper way but it's gotten the job done more than a few times. I'm glad I know it's called paneling, now I'll go see if I can't learn something new.
