如何在 tikz 中的节点之间绘制括号

Question

我有三个盒子。它们位于节点中。我想在它们之间建立如下连接：

\node[cubecontainer] (a) at (0,0) {\cuboid{fill=cyan!20, text=green!50!black, draw=black}
                                  {label=A, width=6, height=20, depth=15, units=mm}};
\node[cubecontainer] (b) at (4,0) {\cuboid{fill=cyan!20, text=green!50!black, draw=black}
                                  {label=B, width=6, height=20, depth=15, units=mm}};
\node[cubecontainer] (c) at (8,0) {\cuboid{fill=cyan!20, text=green!50!black, draw=black}
                                  {label=C, width=6, height=20, depth=15, units=mm}};

我怎样才能使蓝色箭头和红色括号连接它们。我生成三个框的完整代码是

\documentclass[11pt]{article}
\usepackage{tikz}
  \usetikzlibrary{quotes,arrows.meta}
  \tikzset{
    annotated cuboid/.pic={
      \tikzset{%
        every edge quotes/.append style={midway, auto},
        /cuboid/.cd,
        #1
      }
      \draw [\cubeline,every edge/.append style={pic actions, \cubeback, opacity=.5}, pic actions]
      (0,0,0) coordinate (o-\cubelabel) -- ++(-\cubescale*\cubex,0,0) coordinate (a-\cubelabel) -- ++(0,-\cubescale*\cubey,0) coordinate (b-\cubelabel) edge coordinate [pos=1] (g-\cubelabel) ++(0,0,-\cubescale*\cubez)  -- ++(\cubescale*\cubex,0,0) coordinate (c-\cubelabel) -- cycle

      ;
    },
    /cuboid/.search also={/tikz},
    /cuboid/.cd,
    width/.store in=\cubex,
    height/.store in=\cubey,
    depth/.store in=\cubez,

    height=10,
    depth=10,
    units=cm,
    scale=.1,
    line=draw,
    backline=densely dashed,
  }
\newcommand{\cuboid}[2]{
    \begin{tikzpicture}
     \pic [#1] at (0,0) {annotated cuboid={#2}};
    \end{tikzpicture}
}

\tikzstyle{cubecontainer}=[outer sep = 0pt, inner sep= 0pt]

                          line width= 10pt, shorten >=3mm,shorten <=3mm, draw=gray!60]
\begin{document}
\begin{tikzpicture}

                                  {label=A, width=6, height=20, depth=15, units=mm}};
\node[cubecontainer] (b) at (4,0) {\cuboid{fill=cyan!20, text=green!50!black, draw=black}
                                  {label=B, width=6, height=20, depth=15, units=mm}};
\node[cubecontainer] (c) at (8,0) {\cuboid{fill=cyan!20, text=green!50!black, draw=black}
                                  {label=C, width=6, height=20, depth=15, units=mm}};

您可以像任何其他路径一样绘制箭头，并且使用decorations.pathreplacing库完成括号。

\documentclass[11pt]{article}
\usepackage{tikz}
  \usetikzlibrary{quotes,arrows.meta, decorations.pathreplacing}
  \tikzset{
    annotated cuboid/.pic={
      \tikzset{%
        every edge quotes/.append style={midway, auto},
        /cuboid/.cd,
        #1
      }
      \draw [\cubeline,every edge/.append style={pic actions, \cubeback, opacity=.5}, pic actions]
      (0,0,0) coordinate (o-\cubelabel) -- ++(-\cubescale*\cubex,0,0) coordinate (a-\cubelabel) -- ++(0,-\cubescale*\cubey,0) coordinate (b-\cubelabel) edge coordinate [pos=1] (g-\cubelabel) ++(0,0,-\cubescale*\cubez)  -- ++(\cubescale*\cubex,0,0) coordinate (c-\cubelabel) -- cycle
      (o-\cubelabel) -- ++(0,0,-\cubescale*\cubez) coordinate (d-\cubelabel) -- ++(0,-\cubescale*\cubey,0) coordinate (e-\cubelabel) edge (g-\cubelabel) -- (c-\cubelabel) -- cycle
      (o-\cubelabel) -- (a-\cubelabel) -- ++(0,0,-\cubescale*\cubez) coordinate (f-\cubelabel) edge (g-\cubelabel) -- (d-\cubelabel) -- cycle;
      ;
    },
    /cuboid/.search also={/tikz},
    /cuboid/.cd,
    width/.store in=\cubex,
    height/.store in=\cubey,
    depth/.store in=\cubez,
    units/.store in=\cubeunits,
    scale/.store in=\cubescale,
    label/.store in=\cubelabel,
    line/.store in=\cubeline,
    backline/.store in=\cubeback,
    width=10,
    height=10,
    depth=10,
    units=cm,
    scale=.1,
    line=draw,
    backline=densely dashed,
  }
\newcommand{\cuboid}[2]{
    \begin{tikzpicture}
     \pic [#1] at (0,0) {annotated cuboid={#2}};
    \end{tikzpicture}
}

\tikzstyle{cubecontainer}=[outer sep = 0pt, inner sep= 0pt]

\node[cubecontainer] (b) at (4,0) {\cuboid{fill=cyan!20, text=green!50!black, draw=black}
                                  {label=B, width=6, height=20, depth=15, units=mm}};

\draw[line width=2mm, green, -latex, shorten >=1mm, shorten <=1mm] (a.north) --++(90:1cm)-|(c.north);
\draw[ultra thick, red, decoration={brace, raise=5pt, mirror, amplitude=3mm}, decorate] (a.south west) -- (c.south east);
\draw[line width=2mm, green, -latex, shorten >=1mm, shorten <=1mm] ([yshift=-5mm]b.south)--++(-90:1.5cm);
