On wide screens the page is one fixed-height frame: the left list, the centre (model band on top, table below) and the
right results each scroll on their own. The model band is 280–560 px (48vh) and the 3D view follows its container
through a ResizeObserver. The table header stays on top. Below 1100 px the panels stack with a 60vh height limit.

Each block takes the skew of its bearing row against the perpendicular of its stretch axis (rowSkewDeg, from the bearing
azimuth). The blocks and pads are turned to that skew, and the S1/S2 bars are drawn in the block frame and turned with
it, so their lengths and embedments do not change. ② shows the row skew (P1: front −4.42°, back −3.11°). Approved
2026-10-23 with the drawing as reference.

The status line and the backup banner share one row (the banner appears only when a backup exists). Results and notices
show as toasts that close after 4 s; problems stay until closed. The status line keeps only the empty-state hint.

A row can now carry pieces (length, count). C9, C10, C11 and C9·C11 사이 have U and 삿갓 pieces per position (3 loops each);
C12 and C13 have 일자 and ㄷ pieces per bar; P1 and P2 have their splice pieces, each counting all the bars. The
재료표 totals from the pieces, so no bar is left out. 개수 stays the 철근표 count; the piece count is kept beside it. The
삿갓 length h − 100 is an assumption (Q-K5) and is noted on the ④ screen.

The 철근재료표 moves from ③ to a new stage ④ in the header. It shows the checked piers (or the current one), one table
per pier with 강종 → 직경 → 번호 and subtotals, and a total across piers. The Excel export has one sheet per pier and a
합계 sheet. Print uses A4 landscape without the header and buttons. ③ keeps a summary line and a link to ④.
Spec §5, §6.9 and §7 record the stage (approved 2026-10-23).

The quantity table sits below the 철근표 for the whole pier. Lines group by grade and nominal diameter, with
subtotals, unit weight 0.00617·d² (kg/m), the total in kg and ton, and a 할증 total. 할증 is an input in 공통 설정,
default 0 as an assumption. Couplers are counted, not weighed. Bars with no length yet (C9, C10, C11, C12, P1, P2) are
listed as missing and kept out of the totals. The table exports to Excel with SheetJS.

Bars drawn through several points are one tube each, with every bend rounded by R·tan(φ/2) at the centre-line radius
(inner factor × d + d/2). The inside-radius factors (D16 and below, D19–D25, D29–D35, D38 and above) are inputs in 공통
설정, with KDS-based defaults 2 / 3 / 4 / 5. The size-class limits sit in one place (SIZE_CLASS), which also fixes
D25 (25.4) being read as the D29–D35 class in hookLength. The helper bendDeduction gives the centre-line deduction for
the length option, which is not yet applied to the 철근표 lengths.

The three 폐합 of one position were drawn at the same x, so their U bars overlapped. Loop i now sits at x + i·2d and its
삿갓 one bar (d) beside its U, so no U meets another loop's U or 삿갓. The 철근표 counts and lengths are unchanged.
The rule is geometry only; the spec (§4.3) needs the stacking note.

The 철근표 has a selection checkbox per row. Select-all / clear and 선택만 보기 sit above the table. In 선택만 보기 the other
bars are hidden in 3D and the members stay at 50% for context. A 3D click or an alert [보기] selects one bar; the
selection clears when the member tab or the pier changes. The selection is screen state and is not saved to the project.

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.

On ③ the members, the ground and the blinding concrete are drawn at half opacity without depth writes, so the bars show

Role colours stay the default (spec §6.7). A control on ③ switches to diameter (nominal size, H and S of one size

the model has. Highlighting and the state colours are unchanged. Approved 2026-10-23.

The fck row on ② no longer uses the orange changed style, since fck does not change the shape and is not counted in 변경 n건.

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,

- The 3D model of ③ draws each bar family from the rebar modules (coping top and
bottom bars, shear loops, side bars, column bars and ties, footing B1–B8, bearing
S1/S2) and names every bar as its 철근표 number.
- A table row click highlights the bar in 3D (the others dim); a click on a 3D bar
selects its row in the table and sets the member tab. Drags still rotate.
- The rebar is shown only on ③. Not drawn yet: C14, C15/C16, B9–B12, the couplers,

The 3D viewer (views, canvas, part toggles) moves into a slot at the top of ②

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

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).

- 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.

The highlight is the 'current' class, but the stage switch only changed
