TikZ：上一个问题的跟进不再有效

代码来自TikZ：等距离自动换行有效，但我今天注意到它没有产生相同的结果。线条不再重叠。

以下是\listfiles

以下是我使用的代码：

\documentclass[tikz]{standalone}%
% Ensure we are not overriding any existing macro
\newcommand*{\DeltaAngle}{}
\newcommand*{\CurrentStartAngle}{}
\newcommand*{\CurrentEndAngle}{}
\newcommand*{\SegmentedArc}[5][]{%
  % #1 = draw options
  % #2 = number of segments
  % #3 = arc start angle
  % #4 = arc end angle
  % #5 = radius
  \draw[thin, gray] (#5, 0) arc[radius = #5, start angle = #3, end angle = #4];
  % 
  \pgfmathsetmacro{\DeltaAngle}{(#4 - #3)/#2}%
  \foreach \x in {1, ..., #2} {%
    \pgfmathsetmacro{\CurrentStartAngle}{#3 + (\x - 1)*\DeltaAngle}%
    \pgfmathsetmacro{\CurrentEndAngle}{\CurrentStartAngle + \DeltaAngle}%
    \typeout{\string\CurrentStartAngle = \CurrentStartAngle,
      \string\CurrentEndAngle = \CurrentEndAngle}%
    \draw[#1] (\CurrentStartAngle: #5cm) -- (\CurrentEndAngle: #5cm);
  }%
}%
\listfiles
\begin{document}
\begin{tikzpicture}
  \SegmentedArc[thin, red]{4}{20}{100}{2}
\end{tikzpicture}
\end{document}

这是它现在生成的图像：

答案1

你的问题中的代码有一个错误（你复制错了，你链接到的答案中是正确的）：应该是

\draw[thin, gray] (#3:#5) arc[radius = #5, start angle = #3, end angle = #4];

代替

\draw[thin, gray] (#5, 0) arc[radius = #5, start angle = #3, end angle = #4];

仅当您的起始角度恰好为 0 时，您的版本才有效。
