有一段时间没有发博文了，最近有人问到钣金件的相关操作，今天我们来看看钣金零件信息的读取。
Solidworks中钣金件是有一个单独的模块，里面有一些固定的文件夹结构。
最后这个文件夹中包含了展开状态时零件的信息。如长度与折弯线相关的信息都在这里面。
一般我们要找到长 宽 厚 折弯角 与距离 折弯方向 这些信息。
输出结果如下，有些小数的处理就忽略了。大家看看就行。
粗略的写了下，输入信息在这里。很多就是API帮助里面的例子，大家可以在中文翻译中查找到。

//获取当前钣金状态--这个已经过时
//swSMBendStateFlattened 2 = 弯曲变平；该模型回滚到FlattenBends功能之后，但恰好在相应的ProcessBends功能之前
//swSMBendStateFolded 3 = 折弯处已折叠；模型回滚到FlattenBends ProcessBends功能对之后
