^Maybe. But it might also have something to do with the way everything is attached. Everything is just sort of moved into position to intersect the geometry. It doesn't look like it was engineered to fit together.
Yeah, I couldn't put my finger on it, but that does sound about right. If you rotate the nacelles slightly, and add a oblong or rectangular joint for them to intersect with the ring. Not sure how best to improve the connection with the engineering section like upper and lower portions.
Try rotating to nacelles about... 45 degrees so the extruding portions of the upper nacelles point diagonally outwards, and then flip the lower ones upside down and rotate them in a fashion that mirrors the upper half, it'd make a much smoother intersection.
Perhaps an extruding oval shaped joining piece like where the hull and the ring join might work well on the join between the engineering sections?
