1 k3 d1 I% ^' l" c+ t" U# o0 a! j1.Create an instance of the builder object for the desired feature type providing a null object as input.
2 R- r6 j  [( X- b创建一个builder实例，null作为输入
6 ?1 M2 b  x$ h3 p: z2.Edit the properties of the builder object to set the feature parameters and options.
8 Z% J0 a" f* ~' 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.
9 ^6 ?: R5 k4 z! f) B( h8 X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
! ]1 o( q$ l3 o, 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！

代码举例：
Session *NXSession = Session::GetSession();
# S7 {* N0 d/ {: C' M2 Q: d9 Q" ~Part *workPart (NXSession->Parts()->Work());
4 J1 _8 Z6 w; ?5 yFeature *nullFeature (NULL);
Point3d origin = new Point3d(0.0, 0.0, 0.0);
//**************************************************************************

newBlock->SetOriginAndLengths(origin, "50", "80", "100");
