我是 LaTeX 和 TikZ 的初学者，正在尝试制作一份包含一系列键控模式的工业文档。我已设法在附加的 MWE 中生成所需的内容，但我必须手动调整每个半圆在相应六边形中的位置。我想知道是否有更合理的方法来做到这一点……（即将半圆的中心与六边形的中心对齐）。由于我还有许多其他配置要展示，其中每个半圆要放置在不同的角度，我尝试使用 \foreach 循环，但找不到可行的方法……我将不胜感激任何帮助改进代码的帮助。

答案1
我引入了一条新命令：\plug[<opt>]{<internal name>}{<rotation>}{<label>}
<opt>可以是传递给圆的任意 TikZ 内容。
六边形将位于圆的中心以及半圆的中心。
（注意anchor=south！这实际上将南边（半圆直径的中间）置于(c.center)。）<internal name>需要定位以下插头。
但谨防，您必须使用plug<internal name>！<rotation><label>在插头上方放置一个节点。如果您（在用户群中）希望更好地放置这些标签，您可以替换label={[yshift=1mm]above:#4}和
label={#4}对于一次性覆盖，不要使用
<label>，但使用可选参数：\plug[…, label={below:5}]{05}{-60}{}
