我想画一些 3D 立方体。我在如何用乳胶绘制平行六面体和立方体?。
代码部分如下,
\documentclass[border=5pt, multi, tikz]{standalone}
\usetikzlibrary{quotes,arrows.meta}
\tikzset{
annotated cuboid/.pic={
\tikzset{%
every edge quotes/.append style={midway, auto},
/cuboid/.cd,
#1
}
\draw [every edge/.append style={pic actions, densely dashed, opacity=.5}, pic actions]
(0,0,0) coordinate (o) -- ++(-\cubescale*\cubex,0,0) coordinate (a) -- ++(0,-\cubescale*\cubey,0) coordinate (b) edge coordinate [pos=1] (g) ++(0,0,-\cubescale*\cubez) -- ++(\cubescale*\cubex,0,0) coordinate (c) -- cycle
(o) -- ++(0,0,-\cubescale*\cubez) coordinate (d) -- ++(0,-\cubescale*\cubey,0) coordinate (e) edge (g) -- (c) -- cycle
(o) -- (a) -- ++(0,0,-\cubescale*\cubez) coordinate (f) edge (g) -- (d) -- cycle;
\path [every edge/.append style={pic actions, |-|}]
(b) +(0,-5pt) coordinate (b1) edge ["\cubex \cubeunits"'] (b1 -| c)
(b) +(-5pt,0) coordinate (b2) edge ["\cubey \cubeunits"] (b2 |- a)
(c) +(3.5pt,-3.5pt) coordinate (c2) edge ["\cubez \cubeunits"'] ([xshift=3.5pt,yshift=-3.5pt]e)
;
},
/cuboid/.search also={/tikz},
/cuboid/.cd,
width/.store in=\cubex,
height/.store in=\cubey,
depth/.store in=\cubez,
units/.store in=\cubeunits,
scale/.store in=\cubescale,
width=10,
height=10,
depth=10,
units=cm,
scale=.1,
}
\begin{document}
\begin{tikzpicture}
\pic {annotated cuboid};
\pic [fill=magenta, text=blue, draw=blue] at (5,0) {annotated cuboid={width=30, height=5, depth=10}};
\pic [fill=green, text=green!50!black, draw=green!25!black] at (5,-2) {annotated cuboid={width=6, height=20, depth=15, units=mm}};
\pic at (1,-3) {annotated cuboid={width=150, height=200, depth=250, scale=.01, units=m}};
\pic [fill=cyan, text=blue!75!cyan, draw=blue!75!cyan] at (-3,-2) {annotated cuboid={width=15, height=18, depth=13.5, units=}};
\end{tikzpicture}
\end{document}
但不幸的是,我发现我不能使用\usetikzlibrary{quotes,arrows.meta}' because of the error
!我找不到文件tikzlibraryarrows.meta.code.tex'.
我在 Ubuntu 14.04 上使用 Texmaker。
我使用的命令是:
apt-get install texlive
aptitude install pgf
texhash
解决方案是下载新版本的 PGF(zip 文件)。我将其解压缩,然后使用 texhash。这适用于我的情况。
