Represents a ship design seam feature. A seam is a Scantling, Erection, Straking or Intersection type.
Seams are represented with curves on plate systems, and points on profile systems.
Scantling seams indicate divisions in ship structure where differing stock definitions are needed.
Erection seams indicate divisions in ship structure at manufacturing block boundaries.
Straking seams indicate divisions in ship structure to make it a manufacturable size.
Intersection seams indicate divisions in ship structure where other structure intersects the given structure.
Although Scantling seam is the name given to seams that allow for changing stock definitions, all seam types
except straking seams allow for a change in the stock definition.
