TikZ：將水平路徑連接到圓的邊緣

我正在嘗試將 LaTeX 中的圖表從 PNG 轉換為 TikZ。我想要有兩個指向圓的箭頭，分別指向水平方向和指向圓的邊緣。我幾乎透過使用.west座標來實現這一點，但它並不完全對齊：

\documentclass{article}
\usepackage{tikz}
\usetikzlibrary{arrows}

\begin{document}

\begin{tikzpicture}
 [engine/.style={circle,minimum size=6cm,draw=black,font=\large
  }, block/.style={
   rectangle,minimum size=10cm,draw=black,dashed,font=\large
  }, point/.style={
   circle,inner sep=0pt,minimum size=0pt,fill=none
  }
 ]

 % Draw the rectangle containing the block diagram
 \node (block) [block] at (0,0) {};
 % Put a label at the top of the box
 \node (blockname) [point] at (0, 4.5) {\large Module};

 % A circle representing the engine
 \node (engine) [engine] at (1,-1) {Engine};

 % Inputs representing the network ports
 \node (input1) [point] at (-6,-3) {};
 \path (input1) edge [->] node [below] {Network A} (input1-|engine.west);

 \node (input2) [point] at (-6,-0.5) {};
 \path (input2) edge [->] node [above] {Network B} (input2-|engine.west);

 % Output
 \node (output) [point] at (-6,3) {};
 \node (outputup) [point] at (1,3) {};
 \path (outputup) edge [->,dashed]
                  node [above] {Management}
                  node [below] {Output}
                  (output);
 \path (outputup) edge [->,dashed] (engine);

\end{tikzpicture}

\end{document}

這就是我所擁有的：

我認為你可以使用“相交路徑”，TikZ手冊第34頁和第35頁對此進行了描述（http://www.texample.net/media/pgf/builds/pgfmanualCVS2012-11-04.pdf）。

抱歉，由於缺乏時間，我的第一條評論...這是一個完整的示例，您的程式碼顯示瞭如何實現這一目標：

\documentclass{article}
\usepackage{tikz}
\usetikzlibrary{arrows, intersections}

\begin{document}

\begin{tikzpicture}
 [engine/.style={circle,minimum size=6cm,draw=black,font=\large
  }, block/.style={
   rectangle,minimum size=10cm,draw=black,dashed,font=\large
  }, point/.style={
   circle,inner sep=0pt,minimum size=0pt,fill=none
  }
 ]

 % Draw the rectangle containing the block diagram
 \node (block) [block] at (0,0) {};
 % Put a label at the top of the box
 \node (blockname) [point] at (0, 4.5) {\large Module};

 % A circle representing the engine
 \node (engine) [name path=engine, engine] at (1,-1) {Engine};

 % Inputs representing the network ports

 \node (input1) [point] at (-6,-3) {};
 \path [name path=refline] (-6,-3) -- (6,-3);
 \node (intersect) [name intersections={of=engine and refline, by=x}] at  (intersection-1) {};
 \path (input1) edge [->] node [below] {Network A} (input1-|intersect);


 \node (input2) [point] at (-6,-0.5) {};
 \path (input2) edge [->] node [above] {Network B} (input2-|engine.west);

 % Output
 \node (output) [point] at (-6,3) {};
 \node (outputup) [point] at (1,3) {};
 \path (outputup) edge [->,dashed]
                  node [above] {Management}
                  node [below] {Output}
                  (output);
 \path (outputup) edge [->,dashed] (engine);

為了實現它，我創建了一個代表要創建的線的節點，然後創建了另一個代表圓和線之間的第一個交點的節點，最後我將線與最後一個節點連結起來。為此，您還需要使用交集庫，由 : 載入\usetikzlibrary{intersections}。

在此輸入影像描述

我希望它能有所幫助。
