# Okseong pentagon stirrups C9/C11/C13 lap c=630 (수정7 -> 수정8). Based on: Sanoe coping shear bars rebuilt with lap J (drawing shapes II / III / XII / VIII), as in the Daehoji method
#   II  (C7-C9) : lid  (top bar + both legs C=660 down)  +  bottom (bottom bar + both legs full height up)   [vertical stirrup, plane x=const]
#   III (C10)   : left U + right U overlapping J=660 at the middle of the top and bottom edges               [horizontal band, plane z=const]
#   XII (C12)   : same as III with corner R400
#   VIII(C13)   : two hooked pieces overlapping J=660 in the middle of the straight run
