标题: 使用NXOpen删除螺孔
刚学习使用NXOpen，在做一个项目。其中有一个需求，删除部件上的所有直径小于40的螺孔。如下是实现代码：
  1. def remove_holes(file:str, out_file:str, diameter:int):
  2.     theSession  = NXOpen.Session.GetSession()
  3.     basePart1, partLoadStatus1 = theSession.Parts.OpenActiveDisplay(file, NXOpen.DisplayPartOption.AllowAdditional)
  4.    
  5.     workPart = theSession.Parts.Work
  6.     displayPart = theSession.Parts.Display
  7.     partLoadStatus1.Dispose()
  8.     theSession.ApplicationSwitchImmediate("UG_APP_MODELING")
  9.    
  10.     # loop for holes
  11.    for feature in workPart.Features:
  12.        print(f'{feature.Name}')
  13.        if isinstance(feature, NXOpen.Features.Hole):
  14.            holeDiameter = feature.GetDiameter()
  15.            print(f'{feature.Name}, hole diameter: {holeDiameter}')
  16.            if holeDiameter < diameter:
  17.                workPart.Features.Delete(feature)
  18.    
  19.     # save
  20.     partSaveStatus1 = workPart.SaveAs(out_file)
  21.     partSaveStatus1.Dispose()
复制代码
使用这种方式，feature都识别不出来，即"workPart.Features"是空的。

哪位大侠帮忙看看，该如何删除螺孔这个功能呢？

  1. import NXOpen
  2. import NXOpen_Features

  4. theSession: NXOpen.Session = NXOpen.Session.GetSession()
  5. update: NXOpen.Update = theSession.UpdateManager
  6. workPart: NXOpen.Part = theSession.Parts.Work
  7. features: NXOpen_Features.FeatureCollection = workPart.Features
  8. f: NXOpen_Features.Feature
  9. del_holes_mark = theSession.SetUndoMark(
  10.     NXOpen.SessionMarkVisibility.Visible,
  11.     'deleteholes')
  12. for f in features:
  13.     if isinstance(f, NXOpen_Features.HolePackage):
  14.         builder: NXOpen_Features.HolePackageBuilder = features.CreateHolePackageBuilder(
  15.             f)
  16.         if builder.TapDrillDiameter.Value < 40.0:
  17.             update.AddObjectsToDeleteList([f])
  18. update.DoUpdate(del_holes_mark)
