tikz 气动图构建块

Question

我创建了一个小型 tikz 形状库，希望可以方便地反复使用。以下是示例中一起使用的形状子集：

\documentclass[]{standalone}

\usepackage{pgf,tikz}

\begin{document}
\usetikzlibrary{arrows.meta}

\begin{tikzpicture}
%Left-override
\begin{scope}[rotate=270]
\draw (0,0) -- (0,-2.5) --(3,-2.5)--(3,0);
\draw (0.25,-2.25)--(1.5,-1)--(2.75,-2.25)--cycle;
\end{scope}
%horz-3by2solenoid
\begin{scope}[shift={(0,1)},rotate=270]
\draw (0,0) -- (0,5) -- (5,5) -- (5,0) -- (0,0);
\draw[line width = 0.1cm,black] (5,1.25) -- (4,1.25);
\draw[line width = 0.1cm,black] (4,1.75) -- (4,.75);
\draw[-{Triangle},line width = 0.1cm,blue] (5,2.5) -- (0,2);
\draw[-{Triangle},line width = 0.1cm,red] (0,3.25) -- (5,3.75);
\draw (0,5) -- (0,10) -- (5,10) -- (5,5) -- (0,5);
\draw[line width = 0.1cm,black] (5,8.75) -- (4,8.75) node[pos=-0.5]{EB};
\draw[line width = 0.1cm,black] (4,9.25) -- (4,8.25);
\draw[-{Triangle},line width = 0.1cm,blue] (0,6.75) -- (5,6.25)node[pos=1.1]{EA};
\draw[-{Triangle},line width = 0.1cm,red] (5,7.5) -- (0,8) node[pos=-0.1]{S};
\end{scope}
%Right-override
\begin{scope}[shift={(10,-3)},rotate=90]
\draw (0,0) -- (0,-2.5) --(3,-2.5)--(3,0);
\draw (0.25,-2.25)--(1.5,-1)--(2.75,-2.25)--cycle;
\end{scope}
%Right-coil
\begin{scope}[shift={(12.5,-3)},rotate=90]
\draw (0,0) -- (0,-2.5) --(3,-2.5)--(3,0);
\draw (0,-1.5)--(3,-1);
\end{scope}
%some connection lines..
\draw[green](2,1.5)--(2,4)--(20,4);
\draw[green](3,1.5)--(3,3)--(18,3)--(18,-7)--(20,-7);
\draw[green](3.75,-4.25)--(3.75,-5.5);
%Vertical-2wayPiston
\begin{scope}[shift={(20,-12.5)}]
\draw (1,5) -- (1,19) -- (5,19) -- (5,5) -- (1,5);
\draw (0,17) -- (1,17);
\draw (0,6) -- (1,6);
\filldraw (1,15) rectangle (5,16);
\filldraw[fill=white] (2.9,15) rectangle (3.1,1);
\end{scope}
\begin{scope}[shift={(20,-12.5)}]
\draw[{Triangle}-{Triangle},line width = 0.1cm] (7,10)--node[pos=1.1]{OPEN}(7,15);
\end{scope}
%Vertical-speedControl
\begin{scope}[shift={(3.75,-9)},scale=0.75]
\draw (0,4)--(0,3);
\draw (0,1)--(0,0);
\draw (1,0.5) arc (-90:-270:0.9 and 1.5);
\draw (-1,0.5) arc (-90:90:0.9 and 1.5);
\draw [-{Triangle}](-1,1) -- (1,3);
\end{scope}
\end{tikzpicture}
\end{document}

生成以下图像：

将这些积木拼凑在一起以便绘制绿线的最简单方法是什么？我故意没有将它们连接到预期位置以说明难度……但我希望它们在明显的位置连接起来。

任何帮助，将不胜感激。

在您想要连接的点处添加coordinate并使用它们绘制线条。我还添加了用于绘制线条的库calc。它们还可用于定位您的块，例如speed control：

\documentclass[border=5mm]{standalone}

\usepackage{pgf,tikz}

  \end{scope}
  % horz-3by2solenoid

    \draw[line width = 0.1cm,black] (4,1.75) -- (4,.75);
    \draw[-{Triangle},line width = 0.1cm,blue] (5,2.5) -- (0,2) coordinate(BlueArrow);   %%% New coordinate
