突然感觉好久没有写技术文章了，确实，回头看了一下上次的文章，快一个月了。我在忙什么？
文章目录
目标
提示：今天的内容和上一篇属于一个范围，就是工程图的标注
其实代码已经完成好久了，只是没有发文章，今天来说一下孔信息标注的内容。
一、要标什么？
一般来说，工程图上的孔信息主要就是定位与大小，外加上公差 基准这些，但这有点复杂，我们从简，标X 方向 Y 方向 ，再标上孔大小，相同尺寸的合并一下前缀。
二、思路
与上篇类似就是找基准，找孔， 读信息，再标注。
感觉写了很多，但字却很少。 可能是觉得大家都已经学会了。
三、代码
代码有点多，反正我也讲不明白，就贴一下结果。
这样还是会有一些重叠问题，再调用一下自动整理尺寸的功能:

我这功能是抄来的，有问题别问我，哈哈
想要源码的自取
