- chainDims groups the repeated gaps (n@pitch = total) and writes a single gap as its length.
- Top chain: the 전단·띠 stations (C9 @250, C10 @300) from the coping ends.
- Lower chain: the upper C14 bars measured from the column centre (0), so
  the 10@1000 span starts at the column centre.
- Stations are the lowest s of their pieces; pieces within 160 mm are one station.
- P1 gives the 시안 values: 300 · 18@250=4500 · 8@300=2400 · 18@250=4500 · 300 and
  900 · 10@1000=10000 · 900.
