使用 Tikz 连接节点而不跨越其他块
connect nodes with Tikz without crossing other blocks
我想在我的代码中连接块B和M，而不需要连接线“切割”F。如何强制连接扩大连接线并避免F？

\begin{tikzpicture}[auto,node distance=1cm,thick,
main node/.style={black,draw,minimum width=1.5cm,minimum height=0.75cm}]%circle,draw,font=\sffamily\Large\bfseries}]
\node[main node] (L) {L};
\node[main node] (F) [left = of L ] {F};

这就是我现在得到的
这就是我想要的
谢谢！
在 tikz 中没有直接的方法可以做到这一点，但这可以通过添加中间节点来实现。
这里有两种方法。
第一个（蓝色）使用主路径中的边。由于边只有一个分支，因此在适当的位置创建坐标并在另一条边中重复使用。
第二种方式（红色）使用带有多个中间节点的常规 tikz 线。如果需要，它更灵活，可以有任意数量的中间节点。
应调整中间节点的位置以达到预期效果。
