2.Edit the properties of the builder object to set the feature parameters and options.
: U; @: v4 w/ U2 s; u  a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.
6 l6 Y: g& `# v2 K3 z* D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.

编辑特征也是同样的操作过程！

代码举例：
Session *NXSession = Session::GetSession();
