我想绘制块（运输托盘）。每个块宽 0.8m，深 1.2m，高 2.15m，水平放置（只有一个块高度），分组为 2x2、3x3、4x4、5x5、6x6、7x7 块。
我一直在测试两种解决方案“需要帮助从 TikZ 中的一组 2D 节点创建 3D 立方体”但我不知道如何使代码适应我的问题。
例如，我想更改此示例的长方体尺寸：

当我只想绘制 1 层时，它有 2 层块，并且立方体的 xyz 尺寸相同，我想更改长方体的 x、y 和 z 尺寸。
我也测试了第二种解决方案，但仍然无法得到我想要的结果。
如果可能的话，我还想在 x、y 和 z 维度上放置一个标签，其中标明每组块的总尺寸。我不知道标签的文本是否可以与图形的相同侧角对齐。例如，对于 2x2 组块，x 维度为 1.6m，y 维度为 2.15 m（只有一层块），z 维度为 2.4m。
编辑
使用下面的 marmot 解决方案，并且
scalex=0.8,%
scaley=2.0,%
scalez=0.5,%
我想放置具有组各边尺寸的文本。例如：
答案1
我猜你使用的代码没有预见到在给定方向上只有一个立方体。为了解决这个问题，我替换了
\foreach \x in {\steppingx,\secondx,...,\dimx}
经过
\ifnum\dimx=1
\def\lstx{\dimx}
\else
\def\lstx{\steppingx,\secondx,...,\dimx}
\fi
\foreach \x in \lstx
其他方向也类似。除此之外，各个方向的尺寸由 等键设置，我在 MWE 中将scalex其设置为2

更新：我为 egde 标签添加了一些键。但请注意，如果您使用（非常）不同的角度，它们可能看起来不太好。我也没有使用siunitx排版距离（因为我不想用不直接相关的包淹没这个答案）。如果您想要一个标签在所有可能的角度看起来都很好的解决方案，请提出一个单独的问题。
