有趣的食谱格式存在问题

Question

我在网上闲逛时偶然发现了http://graphicalcooking.co。这是一种有吸引力的格式，我对自己说：“TikZ 可以做到这一点！”它确实可以做到。我今天早上一直在努力解决这个问题，并得出了以下结论。我唯一的问题是食谱说明中连接六边形的线条。我想不出一种方法来让各种线条相互交叉（在圆圈位置），而无需明确计算距离。如果有一个宏\connect可以完成这项工作，那就太好了，比如说，通过使用intersectionsTikZ 库。有什么建议吗？我希望我已经对代码进行了充分的注释，这样就不会出现任何谜团了……我提供了几个示例，说明目前虚构的\connect宏可能做什么。

Answer 1

这是一项建议。我认为或多或少地实现了您的命令，只是我用路径的分数替换了第二个绝对距离。我也喜欢食谱中没有菠萝的事实。

但主要的问题是我真的不喜欢洋葱。（这就是我把它们和丑陋的颜色联系起来的原因。）你能把它们去掉吗？（大蒜会更好更健康！）
