fyH and fyS become a grade per prefix (D · H · S), chosen from SD300 · SD400 · SD500. The defaults are the P1 values, so
the P1 results do not change. Each bar takes its grade from its 규격 (fyOf). The 철근표 has a 강도 column. Older files
that stored fyH / fyS are read into the grade map. Only fck is still an assumed value (I02). Approved 2026-10-23.

Role colours stay the default (spec §6.7). A control on ③ switches to diameter (nominal size, H and S of one size
share a colour, Okabe–Ito palette) or member (받침블럭 · 코핑 · 기둥 · 확대기초). The legend lists only the items
the model has. Highlighting and the state colours are unchanged. Approved 2026-10-23.

Each member can take its own fck on its ② card. A member without one uses the ③ 공통 fck, and fy stays common.
The rebar table and the 3D model both read the resolved value. The I02 note stays until every fck member has its
own value. The project file stores the values as optional fckByMember and refuses a bad value on open.
Changing the fck is not a shape change, so it is not counted in the pending changes.

The stair bars in the 철근표 and the 3D model, and the 3D bottom and column bars, were built with the default fck,
so a changed fck did not reach them. buildRebar3D now takes the material, and a material change rebuilds the scene.

The segment table lists each column's Level and the segments between columns

우 경사 3. One column is unchanged.

- Coping §9: C10 at each column centre (@300, k_max as for one column), C9 / C11
outside, and the gaps between columns filled @250 from both C10 groups with the
remaining length shared evenly (추천안, Q-K2). One column gives the T형 result.
- Column bars and couplers repeat per column (P1 230 × 2 for 2주형, × 3 for 3주형).
- Footings: each footing's bars are summed per name; the longest length governs.
- C14 is kept as the T형 layout with an RB-M01 note (per-column rule open, Q-K11).
- Tests: counts for 2주형 and 3주형; T형 unchanged; too-close columns refused.

- 철근표 columns as in the 시안: 구분 · 번호 · 규격 · 간격 · 실간격 · 위치 · 방향 ·

- Material {fck, fyH, fyS}, defaults 27 / 400 / 500 as assumed values (I02).
The rebar calculations take the material: the C7/C8 splice, the P2 development
length, the P3 lap, and the B2 split use it instead of fixed numbers.
- ③ screen: 공통 설정 inputs with a note that the defaults are assumed (I02).
- Project file stores the material as an optional field; older files open with
the defaults.
- Tests: fck 27 → 35 shortens the laps by √(27/35); the C7 piece follows fck;
a non-default fy drops I02; the file round trip.

Cap length = 1740 + 2·l_cap. The shear rows show U and cap ranges.

C15 11 bars, C16 22 bars.

- A 열 is one row across the footing width; each has its own count along the
length. Default floor((L − 1400) / 2250) + 1 per 열, as in spec §4.6.
- Counts are validated: one per 열, whole numbers 2–30. Spacing below the
2250 mm minimum is shown as a warning, not refused (the plan's 6본 → 5@1800
example).
- PierInput gains an optional pileRows; absent means the defaults, so existing
files and the P1 results are unchanged.
- Change tracking compares arrays by value; 열별 본수 can be reverted and
copied (copy item off by default).
- The footing card has −/+ per 열 with spacing, total, and the display string.

The member summary is built from the defaults.
- C6: 전체 선택 acts only on visible, buildable piers; it reads 선택 해제 only
when all of those are checked. A check survives a change of the type filter.
The pier list scrolls past 300 px, for 20 piers.

- planCopy previews the changes and the skipped items for one target; applyCopy

- Default selection copies only the coping width; coping length and pile length

differs. Coordinates, IPs, bearings and elevations are not in any item.
- Equal values are not counted, so the preview count equals the applied count.

- Three values per pier: defaults (as imported), input (generated), draft

- Editable now: 코핑 폭, 코핑 길이, 말뚝 길이. Changing a card does not touch the
3D view until 다시 생성; the header and the card show 변경 n.
- Revert puts a field back to its imported default.
- Project files store defaults and draft (optional; v1 files still open).

- Footings, blindings and piles on a bent axis are placed in their stretch's
frame; 일체기초 is grouped per stretch, so a combined footing never crosses
the kink (separate footings, each aligned with its stretch).
- Footings, blindings and piles are trimmed at the mitre plane like the coping.
- The stage-2 refusal for bent foundations is removed; the Level-half-width
refusal for columns at the kink remains.
- Tests: T형 footing crossing the kink stays in stretch 0; 2주형 with columns
on both sides gives one footing per stretch, with mitre clipping in the scene.

The earlier synthetic bend (IP3 at (6, 2)) put IP4 ahead of IP3 on the turned
line, so the axis folded back on itself. buildPier now refuses a kink behind
IP1 along IP1→IP2 or an IP3 behind the kink along the turned direction. Tests
use IP3 (9, −3.464), a valid 60° right turn with kink (7, 0).
Co-Authored-By: Claude Haiku 5.5 <noreply@anthropic.com>
- buildPier builds on buildAxis: each object carries its stretch k and a local
s from that stretch's base; coping parts are per stretch with the mitre plane
trimming the overlap in the scene (renderer.localClippingEnabled).
- Straight P1 output is unchanged (regression tests pass).
- Bent coping is supported for 현장타설말뚝 only; footings and piles on a bent
axis remain 미실시 until stage 3. Kink outside the coping and columns within
the Level half-width of the kink are refused.
- W03/W04 use coping coordinates (g).
- Tests: constructed 60° bend — world coordinates of bearings, blocks and the
column survive the stretch frames; mitre sides; scene mesh count; refusals.

- buildAxis: IP1 → IP4 → IP3 as stretches with their own frames; arc length s

- copingSpan (centred on L_IP/2) and nearKink (columns within the Level half-width).

- Front and back coping tops that differ by 5 mm or more in any segment are
drawn as two coping parts split at the midline between the bearing rows.
Tolerance 5 mm and midline position are the draft assumptions (Q1·Q2).
- Scene extrudes each coping part across its own width.
- solveIp4 computes IP4 as the intersection of the IP1→IP2 line with the

- Columns closer than one footing length (10400) share a 일체기초 whose
length is the outer-column distance + 10400, centred between them (spec §4.6).
- Pile grid is computed from each footing's length (rows across 8150,
pile count along the length from (length − 1400) / 2250 + 1).
- Blinding concrete follows each combined footing.
