• TikZ reuse code for building nesting pictures or How do I draw shapes inside a tikz node?, etc

• TikZ reuse code for building nesting pictures or How do I draw shapes inside a tikz node?, etc

Update I now have this code, is there a tex-ninja way to get rid of the helper coordinates?

\tikzset{%

        \begin{scope}[scale=.5, shift={(1,0)}]
        \draw (-1,0) coordinate (-in) --  (-1,1) -- (1,0) coordinate (-out) --  (-1,-1) -- cycle;
        \node[anchor=north,inner sep=2pt] at (0,-1) {EDFA};
        \end{scope}

In my diagram I have a few components I reuse a lot, thus making "macros" in tikz for them. The current code I have is using nested tikzpicture environments and is not exactly working as expected. Do you have any suggestions how to improve this?

I found other questions, but none seem to help me?

• this or this, etc
