3 j( Z* N9 H4 l$ j" @. O. G* F& ^Create a New Feature 创建NXfeature的标准过程
1.Create an instance of the builder object for the desired feature type providing a null object as input.
- ^3 }4 f% D, U1 f5 S3 l' ?# O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.
4 F8 u6 \( e# X  `" u  W$ l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.
) M$ G. m* I% I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
4.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！
