저는 tikz를 처음 접했고 결정 상자의 모든 가장자리에서 다른 노드까지 선을 그리는 방법을 이해하지 못합니다.
아래 그림에서 
화살표의 원점을 어떻게 지정하나요? 예를 들어 Decision1의 아래쪽에서 Decision2의 왼쪽 가장자리까지 화살표를 그리고 싶지만 방법을 알 수 없습니다.

가능하다면 솔루션에 대한 설명과 문서에 대한 지침을 알려주시면 감사하겠습니다.
감사해요

이전 줄에 좌표를 배치하면 새 화살표 경로를 배치할 때 그 주위를 탐색할 수 있습니다. .south및 은 원하는 출구 및 진입점에 해당하는 .west노드 decision1및 의 앵커입니다. decision2를 사용하면 xshift...,yshift...선이 바로 위에 있지 않고 이전 선에 가까워지도록 보장됩니다.
일부 구문은 오래되었습니다. 예를 들어 \tikzset대신을 사용해야 합니다 \tikzstyle.
