修改折纸图代码

使用以下修改后的代码这个帖子，在包含其他模型的文档中绘制截头二十面体的一部分（在仍在进行的项目中）；从而生成第一张图纸。

是否可以修改代码（用于此特定模型，而不影响用于文档中其他模型的默认代码），以便五边形可以涂成红色，而长方形可以涂成黄色，如第二张图所示！

定义\filltrue获取下面的图像或\fillfalse仅获取轮廓。由于\iffill可以动态更改为 true 或 false，因此当您想要填充的版本时，您可以将标志设置为 true，然后为所有其他版本将其重置为 false。

我首先创建一个新的 if，\newif\iffill然后在宏定义的开头\PolygReg添加以下行：

\iffill\ifnum#1=5\def\tmp{fill=red}\else\def\tmp{}\fi\else\def\tmp{}\fi

仅当且（即五边形）时，这才会定义\tmp为，否则将被设置为空。然后，在调用路径时，我使用fill=red\filltrue\ifnum#1=5

\expandafter\path\expandafter[\tmp, patron side] let

因此\tmp在执行之前会进行扩展\path。

我对 的定义做了一些类似的事情\Languette，但颜色是金色。

补充

OP 通过评论请求更多功能：

  1. 定义多个默认多边形颜色，

  2. 允许单个 n 边形的颜色覆盖。

楼主尝试解决第 1 点，但忽略了一个重要细节。如果#1匹配没有任何在预先指定的 n 边形默认值中，必须取消填充，否则将使用最后已知的填充。

对于第 2 点，我添加了第二个可选参数\PolygReg，其中fill =可以指定实际选项。

因此，修订后的测试现在

\ifx\relax#2\relax
  \iffill
    \ifnum#1=3 \def\tmp{fill=violet}\else
    \ifnum#1=4 \def\tmp{fill=blue}\else
    \ifnum#1=5 \def\tmp{fill=red}\else
    \def\tmp{}\fi\fi\fi
  \else
    \def\tmp{}%
  \fi 
\else
  \def\tmp{#2}
\fi

这是 MWE。
