LaTeX 中的技术绘图

Question

从评论中获取一些信息并添加更多信息：

有一种类似于 EN ISO 3098 的开放字体可从https://github.com/hikikomori82/osifont使用 XeTeX 或 LuaTeX 就很简单了

\usepackage{fontspec}
\setmainfont{osifont-lgpl3fe.ttf}

要使用它，可以使用 lcdf-tools 或 autoinst 转换为 pdfLaTeX。

@Ross 提到的 dimline 包可能会有所帮助https://ctan.org/pkg/tikz-dimline?lang=en但除此之外，我不知道有任何具体的帮助者

我建议的简化方法包括使用|-和-|以及使用语法++()和cycle。定义尺寸线距离的参数，例如\def\tdHelp{12}或\def\tdDim{10}也可能有帮助。您还可以更多地使用将坐标保存到名称中，就像我在下面的完整示例中所做的那样，只需检查您喜欢的内容即可。

结果如下：

代码如下：

\documentclass[a4paper, landscape]{article}
\usepackage{fontspec}
\setmainfont{osifont-lgpl3fe.ttf}

\usepackage{tikz}
\usepackage{geometry}

\usetikzlibrary{arrows.meta}
\usetikzlibrary{patterns,calc}

\geometry{margin=0mm}
\pagestyle{empty}

\makeatletter

\newlength{\td@FullWidth}
\newlength{\td@HalfWidth}
\newlength{\td@TextSizeL}
\newlength{\td@TextSizeM}

\setlength{\td@FullWidth}{0.50mm}
\setlength{\td@HalfWidth}{0.25mm}
\setlength{\td@TextSizeL}{3.50mm}
\setlength{\td@TextSizeM}{2.50mm}
\def\td@RuleDist{5.00mm}
\def\td@ArrowLength{2.50mm}
\def\td@ArrowWidth{0.669873mm}

\tikzstyle{tdEdge}   = [line width=\td@FullWidth]
\tikzstyle{tdHidden} = [line width=\td@HalfWidth, dash pattern=on 2.50mm off 1.00mm]
\tikzstyle{tdSym}    = [line width=\td@HalfWidth, dash pattern=on 2.50mm off 0.50mm on 0.25mm off 0.50mm]
\tikzstyle{tdHelp}   = [line width=\td@HalfWidth]
\tikzstyle{tdDim}    = [line width=\td@HalfWidth, <->, >={Triangle[length=\td@ArrowLength, width=\td@ArrowWidth]}]
\tikzstyle{tdDimNode}    = [midway,sloped,above,font=\small]

\pgfdeclarepatternformonly{tdRuled}
{\pgfqpoint{-1pt}{-1pt}}
{\pgfqpoint{\td@RuleDist}{\td@RuleDist}}
{\pgfqpoint{\td@RuleDist}{\td@RuleDist}}
{
    \pgfsetlinewidth{\td@HalfWidth}
    \pgfsys@rectcap
    \pgfpathmoveto{\pgfqpoint{0mm}{0mm}}
    \pgfpathlineto{\pgfqpoint{\td@RuleDist}{\td@RuleDist}}
    \pgfusepath{stroke}
}

\def\tdHelp{12}
\def\tdDim{10}
