答案1
distance添加节点时使用的密钥6，
\node [block1, right of=3, distance=8 cm] (6) {Istruttoria};
用于不同的目的。它用于修改曲线to路径的外观，请参阅 /TikZ 3.0.1a 版手册第 70.3 节pgf。要更改您想要的节点分离node distance：
\node [block1, right of=3, node distance=8 cm] (6) {Istruttoria};
但是，below of=您使用的语法已被弃用，我建议您加载positioning库并使用below=of。请参阅PGF/TikZ 中“right of=”和“right=of”之间的区别。您可以修改给定节点的距离，例如。除非该选项处于活动状态，below=3cm of否则距离是在节点边缘之间测量的。on grid
此外，该arrows库被视为已弃用并支持arrows.meta，并且\tikzstyle{foo}=[...]被视为已弃用并支持\tikzset{foo/.style={...}, ...}，因此请考虑更改。
实施这些更改后的完整代码。

这几乎与Torbjørn T.的答案。节点样式定义和节点放置方式略有不同：
