Create a New Feature 创建NXfeature的标准过程
2 I7 L2 V7 T$ q7 h/ ^1.Create an instance of the builder object for the desired feature type providing a null object as input.
; z3 C1 K9 N0 b. [' p! [- z% R: p3 }. I创建一个builder实例，null作为输入
) p/ ~, F- Q" [; w% N  u2.Edit the properties of the builder object to set the feature parameters and options.
4 t9 a. i$ f  J' j8 d% W/ X编辑创建的builder，设置一些参数或者选项
3.Use the Commit method of the builder object to create an instance of the feature.  The Commit method will return the new feature object.
使用commit的方法来创建这个feature的实例，这样就可以返回一个feature对象
8 U# z2 l  x) w. G  t9 C4.Use the Destroy method of the builder object to delete the builder object.
使用destory方法删除builder对象。
编辑特征也是同样的操作过程！
