這裡並不新鮮。但解決方案如下：
我無法讓它發揮作用。
基本上我想要的是定義一個命令，該命令將是一張圖片，並且可以在其他圖片中作為節點使用，類似於形狀的定義方式。這樣我就可以重複使用程式碼，因為每張圖片都有很多元素。請參閱 MWE：

可以看出，圖中的天線放置不正確，因為我draw, shape = circle在第二張圖的節點中使用。另外，如果我加上的話，inner sep = 0pt結果會更糟。我如何在 TikZ 中使用這種嵌套？
答案1
這裡不要使用節點；既不標記路徑上的位置（您可以使用 a coordinate），也不返回該行的頂點，只需使用您已經在那裡使用的路徑（您可以使用之後的路徑node）或者只是重新計算坐標或使用move-tos到那裡（忽略--路徑中的 ）。
我還提供了一種antenna insert path接受一個參數的樣式，即坐標的編號，其餘的是相對 ( +) 以及相對和移動到 ( ++) 運算符的混合。
這對於巨集也同樣有效\MBS。在這裡，我選擇用零dart來繪製outer sep，以便錨點位於線的中間（這需要與繪製天線部分相反（注意它yshift=.8pt來自thick與樣式一起使用的線寬）。
我評論了 的原始放置，\dots並添加了另一種放置點的方法，即使用label( \MUE) 和路徑 ( ) 上的節點\MBS。
隨意不要使用這個。
