' M6 z- x" ?% vCreate a New Feature 创建NXfeature的标准过程
2 N' ]5 u; J, m' k2 }9 P) [1.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.
编辑创建的builder，设置一些参数或者选项
# j& }' u  U0 x6 ~. C$ {2 Z8 ~! k: u3.Use the Commit method of the builder object to create an instance of the feature.  The Commit method will return the new feature object.
. p" O, B% U2 v3 `  L( r3 n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！

代码举例：
Session *NXSession = Session::GetSession();
- K6 y. W  E1 p: h  c& kPart *workPart (NXSession->Parts()->Work());
Feature *nullFeature (NULL);
Point3d origin = new Point3d(0.0, 0.0, 0.0);
