由于个人XX，目前会使用SolidWorks，需要加工的模型要出工程图，而模型中的“数量”这个属性是由手工添加进去的，这就导致了可能出现手工填写出错的情况。如果某个零件只需要1个，结果不小心写成了2个，一旦东西做出来之后心里会有一万只草泥马在奔腾了吧。所以我秉承着没有工具就自己做，能动手就少BB的思想，决定开发一个功能，来自动检查模型中的“数量”这个属性是否有误，一劳永逸的解决这个问题，提高设计的准确率。
思路如下：获取总装配体中所有零件的BOM，这个BOM应该是完全正确的，因为你装配了多少零部件进去，这个BOM中的量就是多少。然后再逐一获取每个零件中的“数量”这个属性，并进行对比，对比后将结果导出为EXCEL，以供查询。
这里我采用的是遍历整个装配体的方式来获取BOM，不好意思，这一段核心代码我真的是在书上抄的，感谢 SOLIDWORKS API二次开发实例详解（微视频版）这本书，有兴趣的同学可以买一本，要支持正版啊，鄙视白嫖！
