* M02_CF_Diagram.ts
|

* 단가산출 다이어그램 — 자유 배치(정함 점검 8 · 9 · 12 · 「상자 · 선 약속」)
|
||
* 상자(입력 · 함수 · 출력)를 끌어 아무 자리에 놓음(on.move) · 판 끌기 · 확대 / 축소 · 「한눈에」 · 「줄 맞추기」 ·
|

* 상자 = 종류 · 이름 · 오른쪽 위 단위 · 색 · 왼쪽 받는 알약 · 오른쪽 내보내는 알약(알약에 지금 값) ·
|
||
* 선 = 굽은 선 · 내보내는 알약을 끌어 받는 알약에 놓으면 on.link(막히면 까닭 한 줄) · 고른 상자와 이어진 선만 진하게.
|
||
* SheetLogic 다이어그램(M01_SL_Diagram)을 옮겨 고쳐 씀 — 그 파일에 기대지 않음. 그리기만(바꾸는 것은 부른 쪽이 Model 로).
