I have the following simple code:

    \draw[line width=2pt] (0,0) to (0,4) node[above]{\text{D1}};
    \draw[line width=2pt] (0,0) to (4,0) node[right]{\text{D3}};
    \filldraw (0,0) circle (3pt);
    \draw[snake=coil,segment aspect=0, line width=1.5pt, red] (0,1)  -- (1,0); 
    \draw[snake=coil,segment aspect=0, line width=1.5pt, green] (1.5,0) arc (180:0:1cm);

I want to make the arc to be snaky as the other red line. However, the code does not work. How can I make the green arc snaky?

    @percusse Would you like to write an answer? – CarLaTeX Nov 9 '17 at 5:19
  • @percusse, just another question: is it possible to adjust the segment aspect=0 for the arcs? – QGravity Nov 11 '17 at 6:15
  • @QGravity Yes, you can find examples in the manual. – percusse Nov 18 '17 at 3:50

snake=coil is a lucky miss such that snake is defined as the name of decoration and because of that supplying a value doesn't cause anything to happen. Hence if you fix the decoration name then it works. Hence instead of snake=coil use decoration=snake,decorate
