我正在使用特定的类文件fundam.cls。但是，当我添加 tikz-cd 包时，底部边距会超出范围。我怀疑这是因为 tikz-cd 包正在更改纸张类型，使其变小。
以下是不良行为的最小工作示例：

\section{Introduction}
The \emph{Fundamenta Informaticae\/} class file is based on the
standard \LaTeXe\ \texttt{article} class as described in the \LaTeX\
manual. It means that the paper prepared to be process with the
standard \texttt{article} class can be processed with the
\texttt{fundam} class without any modifications. Commands which
differ from the standard \LaTeX\ interface, or which are provided in
addition to the standard interface, are explained in this guide. This
guide is not a substitute for the \LaTeX\ manual itself.
The \texttt{fundam} class can be used only with \LaTeXe. It is not
supposed to work with the obsolete 2.09 (or earlier) version of
\LaTeX.

没有 tikz-cd 包，它也能完美运行。
答案1
graphicx我刚刚在课堂上遇到了与包相同的问题fundam。我尝试了@egreg提供的解决方案，但不幸的是，这对我没有用。
我仔细观察了fundam.cls 文件并查找\paperlength和值\paperwidth。在那里我发现\topmargin -2cm115 行被评论了。删除评论解决了我的问题。

答案2
其实不问题；这只是软件的最新版本处理输出页面尺寸的方式。
该fundam班级来自 1998 年，其分页参数设置为使得文本块（几乎）位于 A4 纸的中心。
然而，最近版本的 LaTeX 试图更好地解决这个问题，因此它们做根据\paperwidth和的值设置纸张宽度和高度\paperheight。加载后立即发生此操作graphicx（TikZ 会执行此操作）。
补救措施很简单：之前\begin{document}将纸张参数重新设置为A4。
\documentclass{fundam}
\usepackage{tikz-cd}
% everything has been set; reset the page dimensions to A4
\setlength{\paperwidth}{21cm}
\setlength{\paperheight}{29.7cm}
