"""Ramp-A P1 column rebar reading (G2: P1 main, P2 hoops, P3 ties) from D2 -> 판독/g2_values.json.

D2 front view: column CL x 12741.4; shaft top (EL 45.452) at y -700829.1, coping bottom (EL 57.452) at y -692829.1;
the view is broken between y -696879.1 and -696779.1 (4,000 hidden): EL = 45452 + (y + 700829.1) [+ 4000 above].
Left dimension chains (ticks at x 8216 '띠철근외측' and x 7716 '크로스타이') give the hoop / tie zones.
Section C-C (centre 1045.1, -698159.3): main bars = INSERT symbols on r 875.
