使用 Tikz 对文本进行 3D 投影

Question

我对显示元素间间距的文本有疑问，我希望它与我的结构处于相同的方向，有没有简单的 Tikz 解决方案？

代码 ：

\documentclass{article}
\usepackage{tikz}
\usepackage{tikz-3dplot}
\tdplotsetmaincoords{40}{-30}

\begin{document}
\begin{tikzpicture}[tdplot_main_coords]

\def \r{0.5};
\def \d{1.5};
\def \nx{2};
\def \ny{2};
\def \bord{0.11};
\def \hsub{0.1};

\definecolor{cuivre}{rgb}{0.9,0.7,0.4};
\definecolor{ceram}{rgb}{0.92,0.95,0.95};

%masse
\filldraw[fill=gray] (\d-\r-\bord,\d-\r-\bord,-\hsub) 
        --++ (\nx*\d-\r/2,0,0)
        --++ (0,\ny*\d-\r/2,0)
        --++ (-\nx*\d+\r/2,0,0)
        -- cycle; 

%cadre
\filldraw[fill=cuivre] (\d-\r-\bord,\d-\r-\bord,0) 
        --++ (\nx*\d-\r/2,0,0)
        --++ (0,\ny*\d-\r/2,0)
        --++ (-\nx*\d+\r/2,0,0)
        -- cycle; 

%sub1
\filldraw[fill=ceram] (\d-\r-\bord,\d-\r-\bord,0) 
        --++ (0,0,-\hsub)
        --++ (0,\ny*\d-\r/2,0)
        --++ (0,0,\hsub)
        -- cycle;

%sub2
\filldraw[fill=ceram] (\d-\r-\bord,\d-\r-\bord,0) 
        --++ (0,0,-\hsub)
        --++ (\nx*\d-\r/2,0,0)
        --++ (0,0,\hsub)
        -- cycle;

%trous
\foreach \x in {1,...,\nx}{
    \foreach \y in {1,...,\ny}{
        \filldraw[fill=ceram] (\d*\x,\d*\y,0) circle (\r);  
    }
}

\foreach \x in {2,...,\nx}{
    \foreach \y in {2,...,\ny}{
        \filldraw[fill=ceram] (\d*\x-\d/2,\d*\y-\d/2,0) 
        circle (\r);  
    }
}

%espace inter trou 1
\draw[dashed] (\d, \nx*\d,\hsub) --++ (0,1.5,0);
\draw[dashed] (2*\d, \nx*\d,\hsub) --++ (0,1.5,0);
\draw[<->] (\d, \nx*\d+1.5,\hsub) -- (2*\d, \nx*\d+1.5,\hsub) node
[font=\footnotesize,midway, fill=white, anchor=center]{1.5mm};

\end{tikzpicture}
\end{document}

只需添加sloped作为最后一个节点的参数。above使文本不超过线。

\documentclass{article}
\usepackage{tikz}
\usepackage{tikz-3dplot}
\tdplotsetmaincoords{40}{-30}

\begin{document}
\begin{tikzpicture}[tdplot_main_coords]

\def \r{0.5};
\def \d{1.5};
\def \nx{2};
\def \ny{2};
\def \bord{0.11};
\def \hsub{0.1};

\definecolor{cuivre}{rgb}{0.9,0.7,0.4};
\definecolor{ceram}{rgb}{0.92,0.95,0.95};

%masse
\filldraw[fill=gray] (\d-\r-\bord,\d-\r-\bord,-\hsub) 
    --++ (\nx*\d-\r/2,0,0)
    --++ (0,\ny*\d-\r/2,0)
    --++ (-\nx*\d+\r/2,0,0)
    -- cycle; 

%cadre
\filldraw[fill=cuivre] (\d-\r-\bord,\d-\r-\bord,0) 
    --++ (\nx*\d-\r/2,0,0)
    --++ (0,\ny*\d-\r/2,0)
    --++ (-\nx*\d+\r/2,0,0)
    -- cycle; 

%sub1
\filldraw[fill=ceram] (\d-\r-\bord,\d-\r-\bord,0) 
    --++ (0,0,-\hsub)
    --++ (0,\ny*\d-\r/2,0)
    --++ (0,0,\hsub)
    -- cycle;

%sub2
\filldraw[fill=ceram] (\d-\r-\bord,\d-\r-\bord,0) 
    --++ (0,0,-\hsub)
    --++ (\nx*\d-\r/2,0,0)
    --++ (0,0,\hsub)
    -- cycle;

%trous
\foreach \x in {1,...,\nx}{
\foreach \y in {1,...,\ny}{
    \filldraw[fill=ceram] (\d*\x,\d*\y,0) circle (\r);  
}
}

\foreach \x in {2,...,\nx}{
\foreach \y in {2,...,\ny}{
    \filldraw[fill=ceram] (\d*\x-\d/2,\d*\y-\d/2,0) 
    circle (\r);  
}
}

%espace inter trou 1
\draw[dashed] (\d, \nx*\d,\hsub) --++ (0,1.5,0);
\draw[dashed] (2*\d, \nx*\d,\hsub) --++ (0,1.5,0);
\draw[<->] (\d, \nx*\d+1.5,\hsub) -- (2*\d, \nx*\d+1.5,\hsub) node
[font=\footnotesize,midway, fill=white, anchor=center,sloped, above]{1.5mm}; %here's the trick

\end{tikzpicture}
\end{document}
