Create a New Feature 创建NXfeature的标准过程
9 z4 i! H& @6 k# T+ P8 U" P6 j1.Create an instance of the builder object for the desired feature type providing a null object as input.
创建一个builder实例，null作为输入
2.Edit the properties of the builder object to set the feature parameters and options.
1 z0 n6 ^6 y8 R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.
( D. N3 z0 L3 F4 b) c1 g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
5 ?1 `1 |( ?. y; r* ^4.Use the Destroy method of the builder object to delete the builder object.
使用destory方法删除builder对象。
