"""B07 횡단도 [확정]은 설계 **상태만** 올린다 — 정본 설계값을 덮지 않는다 (2026-09-14 브레인 ②).

실측(936be972 · 읽기만): 옛 [확정]은 입력 셋(지반·단면·측구 쪽)만으로 단면적을 다시 계산해
설계를 통째로 덮었다 — 62측점 전부 단면적이 바뀌고(절토 −20.8% · 성토 +5.8%) 암선·절토경사·
표준 횡단·구조물 트림이 빠졌으며, 종점 1078.01 은 **사용자가 끈 측구가 켜졌다**.
B07 CAD 에는 설계를 고치는 자리가 없으므로 덮을 값이 없다 — 「반만 계산할 거면 반만 덮는다」.
