使用 tikz 的概念图

Question

我对 Latex/Tikz 并不陌生，但对于我之前的 tikzpictures，指定坐标并连接它们或使用 arc 和一些简单的节点命令就足够了。我搜索了很多类似的 tikzpicture，不敢相信没有人使用 tikz 来做这样的事情。所以我决定在这里提问。我希望你能帮助我。我试过用 powerpoint 来做，但看起来一点也不好，尤其是在 letex 文档中。

我想用这个替换text3，text4和text8的矩形。

 \draw (box4.east) |-(box1);    % i want to connect with a square angle but with an staigt line (e.g. powerpoint figure)

% try to do the big rectangle for text12
% \node[bigbox=text12, fit=(box1)(box2)(box3)(box4)] (D) {}; %doesn't work (i tried to put the 4 boxes into one big box and put the text12 to bottom right)

由于我的声誉不够，我似乎无法发布结果。

我没有发布最少的示例，因为我觉得我走错了方向。我并不指望有人能解决我的案子，但我希望你能给我展示一个已经解决类​​似问题的帖子

无关：

• 没有 MWE（最小（非）工作示例）的问题属于“为我做”类型，不太可能在这里得到解答。

主题明确：

• 您所寻找的形状可以定义如下：

   box/.style = {draw, inner sep=2mm, 
              minimum height=#1,  minimum width=22mm},
 box/.default = 6mm,
    SR/.style = {box, signal, signal to=east, on chain},
   SLR/.style = {box, signal, signal to=east and west, on chain},

（形状详情signal请参阅67.4 符号形状在 TikZ 和 PGF 手册 v3.0.1a，第 712-714 页中），然后用作：

\node (n1) [SR]     {text 3};
\node (n2) [SR]     {text 4};
\node (n3) [SLR]    {text 8};

• 这应该可以作为你的 MWE 的起点 :)。结果可能是这样的：

编辑： 我确实使用了以下 MWE：
