Panels with notches for seams/butts in the shell plating will have one GSD on either side of the seam/butt to be used for the alignment of the shell plate. This type of GSD is only placed along a shell curve.
The distance of the GSD from the seam/butt is defined by the variable (SEAM_DIST).
These marks will be placed on the marking side of the panel (see the figure below).
