使用NXOpen C++创建和编辑特征的详细过程，一看就会！

* S% @4 M) \2 b+ _Create a New Feature 创建NXfeature的标准过程
4 K* d. N( K2 }7 O% d* Y1.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.
& J: Q  b" e: r3 |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.
0 X1 V+ _' k: y4 z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！
