是否正确剪辑了 3D tikz 以适应调整框？

Question

考虑以下 MWE：

  \tikzstyle{rr} = [draw,fill=gray,opacity=0.5];

    \draw[rr] (0,0) rectangle (15,27);
    \node[draw,align=left,anchor=south west] at (3,3.5) {\loremnchars[6]{60} \\ \loremnchars[7]{60}};

  \begin{scope}[canvas is yx plane at z=2.0]

      \node[draw,align=left] {\loremnchars[2]{60} \\ \loremnchars[3]{60}};
    \end{scope}
  \end{scope}

  \begin{scope}[canvas is yx plane at z=4.0]
    \draw[rr] (0,0) rectangle (15,27);
    \node[draw,align=left,anchor=south west] at (3,5.5) {\loremnchars[8]{60} \\ \loremnchars[9]{60}};
  \end{scope}

\end{tikzpicture}
\end{adjustbox}

\end{center}

\end{document}

当标记%L1和%L2注释的行如在 MWE 中一样时，我会按预期在页面中得到图像（单击可获得全尺寸）：

不幸的是，我有一堆像这样的节点%L1，它们位于 3D 范围之外，这会弄乱adjustbox边距计算。因此，由于我需要这些节点，我想 - 也许我可以剪辑而不删除这些节点。不幸的是，当我尝试这样做时 - 通过取消注释上面 MWE 中的%L1和%L2行 - 然后我得到了一个混乱的剪辑，并且节点的影响仍然可见：

所以我的问题是 - 我该如何剪辑tikzpicture，以便节点%L1保留，但我仍然获得与第一个屏幕截图相同的边距和透视？

如果你有意，你可以使用pgfinterruptboundingbox

   \begin{pgfinterruptboundingbox}
   \node[] (tt) at (33,22) {};    %L1
   \end{pgfinterruptboundingbox}

但请记住，边界框不会调整到页面内，并且使用您提供的坐标L1（即(tt)），如果您在节点中放置任何内容(tt)，它都会超出页面。

正如 percusse 所指出的，添加overlay选项具有相同的效果。

\node[overlay] (tt) at (33,22) {};    %L1
