LaTex: Turning off subsection numbering for a subfile

I'm using a .tex file as a subsection in my main .tex file. In the main.tex file I have:

\documentclass{article}

\usepackage{subfiles}

\begin{document}

\subsection{Section title}

\subfile{sub.tex}

\subsection{Section 3 title}

\end{document}

The sub.tex file is similar to:

\documentclass[main.tex]{subfiles}

\begin{document}

\subsection{Section 2 title} 

.
.
.

\end{document}

I want to keep the section numbering when I create a PDF of the main.tex file, but I'd like to NOT have the subsection numbering when I generate a standalone PDF from the sub.tex file.

I searched around and found somethings that kind of did what I wanted, but I was hoping, in keeping with the subfiles package, there was an elegant way to do this?

Solution

  • You could change the senumdepth in the preamble of the subfile. This won't influence the main file.

    \documentclass[main]{subfiles}

\setcounter{secnumdepth}{0}

\begin{document}

\subsection{Section 2 title} 

.
.
.

\end{document}

    If you'd like to change this for all subfiles:

    \documentclass{article}

\usepackage{subfiles}

\ifSubfilesClassLoaded{\setcounter{secnumdepth}{0}}{}

\begin{document}

\subsection{Section title}

\subfile{sub}

\subsection{Section 3 title}

\end{document}
