교대 3D는 받침블럭 콘크리트와 몰탈패드만 그렸다. ② 받침 카드와 같은 솔플레이트(abutSoles)로 교각처럼 그린다. - 받침 본체: 솔플레이트 평면에서 사방 100 mm 뺀 상자, 높이 h3, 패드 상면에서 - 솔플레이트: L은 거더 방향(블럭 회전 = 방위각, 적용한 계산 방위각 포함), W는 그 직각, T1은 오르막 쪽 - 거더 하면 고정: T ≠ T_ref이면 블럭 상면 · 패드가 (T − T_ref)만큼 내려감 (받침 ELEVATION TABLE과 일치) - 부재 표시: '받침·받침블럭'에 교대 bearings, '솔플레이트'에 교대 solplates 연결 - 테스트: A1(짝 P1) 본체 높이 245 · 솔플 상면 z + 245 + 38, 두꺼운 끝이 오르막(A1) 쪽, S −3 % → 패드 −4 mm · 상면 유지, soles 없이 부를 때 기존 형상. 브라우저: 교대만 · 교각+교대 가져오기 예외 0, 받침 쌓임 확인 Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>
