Now I’m confused. Why does the process of building the thing in sections leave visible seams behind? I mean, they’re LEGOS! Why would the finished product display larger seams than the relatively tiny one between any two bricks? I would have thought that, even if the sections don’t actually interlock, it should be possible to snug them up together neatly so that the seams don’t show.
Evidently, the ship was built in sections so it’s transportable. As for why gaps are visible between them, if you look at the left side ofthe hull in this pic, (especially to the immediate left of the upper blue section) you can see that the bricks don’t stay together perfectly, so it’s understandable that there’s some accumulated error in something this big, and the mating surfaces are a bit bowed, preventing them from sitting side by side perfectly.
