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.

On ③ the members, the ground and the blinding concrete are drawn at half opacity without depth writes, so the bars show
through. Outside ③ each part returns to its own opacity. Rebar colours are shaded to 0.8 and slightly glossier so they
read through the members. Approved 2026-10-23.

- 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.

- 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.

- 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
line through IP3 turned by the bend angle (positive = counter-clockwise,
sign convention to be confirmed). Bent coping geometry remains 미실시.

- three.js scene in the pier frame (pivot at first column centre)
- coping as extruded elevation outline; columns, footings, piles, blinding, bearing blocks and pads
- four view presets, per-part visibility toggles
- workbook load (sample or file), result table, issue list and undetermined defaults
- frame orientation test and bounding-box test
