* D03 손 긋기 겹 · 그리기 칸(PLAN 562-3 · 요구서 389 3장 8~10) — 시점에서 점을 찍어 직선으로 이음.
|
|
*
|
|
* 본선 = D02 시점에서 · D02 종점 둘레(SNAP_PX)에 오면 종점에 붙고 그 점에서 끝.
|
|
* 미리보기 = 마지막 점 → 마우스 길이(m) · 원지반 기울기(%, + 오르막) — 제약 칸 넷:
|
|
* 자유 · 길이 고정 · 기울기 고정(마우스 방향 첫 자리) · 둘 다(양각기 원 위 후보 중 마우스에 가까운 것).
|
|
* 갈래 = 기존 선 꺾임점(선 위면 꺾임점 끼움)을 눌러 시작 · 구역 마크 = 선 위 누름(오른쪽 = 지움).
|
|
* 키 = Enter 끝 · Esc 이번 긋기 취소 · Backspace 마지막 점 빼기(설정 창 단축키 표 D03 줄).
|
|
* 셈 = 562-1 짝(`logic/D03_PlanAnalysis_Draw`) · 꼴 다루기 = `logic/D03_PlanAnalysis_Plan` ·

* 값을 바꾸면 `commit(다음 꼴)` 한 번 = 되돌리기 한 걸음(스택 · 캐시 = 페이지).
