% \3 ^3 N5 m- }1 eCreate a New Feature 创建NXfeature的标准过程
  U5 b6 ?$ ~, t% d: u8 b$ H1.Create an instance of the builder object for the desired feature type providing a null object as input.
' R& c" f* _; r& y" L创建一个builder实例，null作为输入
( ^/ z7 T$ `0 w' h6 a0 I2.Edit the properties of the builder object to set the feature parameters and options.
& d# u4 ]: n; H5 [; ^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' `$ X9 R$ @' t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
/ P& i4 Y: h/ S2 L$ Q3 {8 b4.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！
