**********************************************
上面程序运行前，假设你选择了一个简单直孔特征。然后得到这个孔德一些参数。
孔深、直径等。
solidworks的API虽然是e文的。介绍的还算详细，并且有很多的example。大家可以多看看代码。
要访问一个特征，需要经历这样的步骤：
定义一个特征对象： dim....as ...
得到这个特征 ：比如使用GetSelectedObject5 还有SelectebyID等...
得到定义：GetDefinition
进行访问：AccessSelections
上面的程序没有if选择的容错机制，需要添加上。
