Create a New Feature 创建NXfeature的标准过程
+ o) J+ @/ H3 |) d4 P# d1.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.
& H  X, `* b- Q. z编辑创建的builder，设置一些参数或者选项
3 u0 m& S2 p; M6 t" _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
( \  J* j0 B& w/ V# y4.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！
