如何在表示服务器图形的矩形上方绘制实心矩形？

Question

嗯，这是一个系统的方法。

检查并尝试您的代码向我展示了两个问题：

定位：其实没必要，而且会使代码复杂化
梯形形状有问题；最好避免

以下是我的路线：

引入一个\pic叫做serv
在里面画serv/.pic{}任何需要的东西
serv手动放置几张图片
最后手工放置一个圆圈

为了重新绘制一个服务器单元，我使用了像这样的帮助网格来估计绝对坐标；从你的绘图中；（0,0）位于最低矩形的中心：

现在，此代码绘制：

一个服务器（根据您的口味调整）
首先，矩形
第二，梯形作为一条封闭的路径
第三，带有白色“框架”的旋钮
最后，一个缝隙，放置多次

% new
\tikzset{
    % ~~~ a server-pic with known dimensions ~~~~~~~~~~
    serv/.pic={
        \draw[fill=orange!30] (-1.2,-.3) rectangle (1.2,.3);% rectangle
        \draw[fill=orange!30] (-1.2,.3) -- (-.7,.9) -- (.7,.9) -- (1.2,.3) -- cycle;% trapezoid
        \draw[fill=white,draw=white] (.9,0) circle [radius=1mm];% knob with a white frame
        
        \foreach \i in {0, .3, .6, .9, 1.2}% some slits
            \draw[,draw=white,line width=1.6mm] (-1+\i,-.22) -- (-.8+\i,.22);
            % one slit; stroke is quite thick
    }
}

缝隙只是简单的粗笔画，因此用白色绘制它们也会填充其内部。如果你想让它们更有角度，请用封闭路径替换我的单笔画，就像我对梯形所做的那样，并选择较小的线宽。

请将一开始的代码与您当前的版本进行比较，同时观看% comments。
