`node distance=#1` 在 TikZ 3.0 下似乎无效

我在升级之前没有遇到这个问题（注意node distance=5in）：

\documentclass[tikz]{standalone}

\usetikzlibrary{arrows}
\tikzset{
  node distance=3cm,
  graph vertex/.style={
    circle,
    draw,
    minimum size=7.5mm,
  },
  graph directed edge/.style={
    >=stealth,
    ->,
    semithick,
  },
}

\begin{document}
  \begin{tikzpicture}[node distance=5in]
    \foreach \posx/\posy/\name in {
      1/3/A,
      0/3/B,
      2/3/C,
      3/3/D,
      1/2/E,
      3/2/F,
      0/1/G,
      2/1/H,
      1/0/I,
      3/1/J}
    \node[graph vertex] (\name) at ((\posx,\posy) {\name};
  \foreach \source/\sink in {A/C,A/H,B/A,B/G,C/D,D/F,E/A,E/I,F/J,G/I,H/F,H/G,I/H,J/C}
    \path[graph directed edge] (\source) edge (\sink);
\end{tikzpicture}
\end{document}

节点距离控制物体相对于彼此放置时的自动距离。简单的例子；

\documentclass[tikz]{standalone}
\usetikzlibrary{positioning}
\begin{document}
\begin{tikzpicture}[every node/.append style={circle,draw,inner sep=1pt}]
    \node[] (A) {A};
    \node[left=of A] (B) {B};

    \begin{scope}[node distance=2cm]
    \node[right=of A] (C) {C};        
    \end{scope}

    \begin{scope}[node distance=1mm]
    \node[above=of A] (D) {D};        
    \end{scope}
\end{tikzpicture}
\end{document}

关于您的scale问题，它是图片或节点键，因此必须在正确的上下文中读取。只有，

\tikzset{scale=3}

不会调用任何东西，因为每个 tikzpicture 环境都需要在初始化期间读取它。如果我理解你的评论正确的话，你可以将此类规范放在键中every picture。使用句柄/.prefix style可以在个别情况下覆盖它，例如，

\documentclass{article}
\usepackage{tikz}
\tikzset{every picture/.prefix style={scale=3}} % For every tikz picture

\begin{document}

    \begin{tikzpicture}[] %scale=3
    \draw  (0,0) -- (1,0);
    \end{tikzpicture}


    \begin{tikzpicture}[scale=0.5]% Overrides the key on this one since those keys are prefixed
    %Now the scale is 1.5!!! Transformations are cumulative
    \draw  (0,0) -- (1,0);
    \end{tikzpicture}

    \begin{tikzpicture}[reset cm,scale=0.5]% Overrides the key on this one since those keys are prefixed
    %Now the scale is 0.5!!! We reset the transformation
    \draw  (0,0) -- (1,0);
    \end{tikzpicture}

\end{document}

适用于你的例子

\documentclass[tikz]{standalone}
\usetikzlibrary{arrows}
\tikzset{%node distance=3cm,
  graph vertex/.style={
    circle,
    draw,
    minimum size=7.5mm,
  },
  graph directed edge/.style={
    >=stealth,
    ->,
    semithick,
  },
  every picture/.prefix style={scale=3}
}
\begin{document}
  \begin{tikzpicture}[]
    \foreach \posx/\posy/\name in {
      1/3/A,
      0/3/B,
      2/3/C,
      3/3/D,
      1/2/E,
      3/2/F,
      0/1/G,
      2/1/H,
      1/0/I,
      3/1/J}
    \node[graph vertex] (\name) at ((\posx,\posy) {\name};
  \foreach \source/\sink in {A/C,A/H,B/A,B/G,C/D,D/F,E/A,E/I,F/J,G/I,H/F,H/G,I/H,J/C}
    \path[graph directed edge] (\source) edge (\sink);
\end{tikzpicture}
\end{document}

如果您还希望将转换应用于节点，则需要将transform shape键放在样式中或明确地放在节点选项中。
