Tikz 如何从节点绘制到页面边缘

Question

鉴于

\documentclass{article}
\usepackage{tikz}
\usepackage[explicit]{titlesec}
\usepackage{geometry}
\usetikzlibrary{shapes.geometric}
\usetikzlibrary{shapes,shadows,calc}

\newcommand*{\MyNode}[1]{%
    \begin{tikzpicture}[
    node distance = 2mm,
    S/.style = {signal, fill=orange, 
        signal to=east,
        minimum height=3ex,
        text depth=0.25ex,
        inner sep=7,
        font=\sffamily\bfseries}
    ]
    \node (n1) [S] {\color{white} \huge\textbf{\fontfamily{ppl}\selectfont{#1}}};
    \draw [line width=0.7mm, black] (n1.east) -- (\textwidth-3cm, 0);

    \end{tikzpicture}
}
\titleformat{\section}
{\normalfont}{}{0em}
{\MyNode{#1}}
%

\begin{document}
    \newgeometry{left=1cm,right=1cm, bottom=1cm}
    \section{Education}
    \section{Personal Projects}
\end{document}

产生输出

我想找到一种方法，让线条延伸到页面的右边距。

---

我尝试过的事情

我在网上查找了将右页边距绝对位置表示为变量的方法，Tikz但没有成功。我进一步搜索了如何从内部存储给定形状的宽度值，Tikz以便我可以做到\textwidth - \shapewidth，但也没有成功。

有谁知道我怎样才能实现这个目标？
