Let's assume there are already two face named selection in the tree, named MyNS1 and MyNS2.

To create another Named Selection, one can use:

  NamedSelections=ExtAPI.DataModel.Project.Model.NamedSelections
  MyNewNS=NamedSelections.AddNamedSelection()

The name of this new Named Selection can be changed through:
```
  MyNewNS.Name="MyNS3"
```

To define the scoping of this third Named Selection, one should first retrieve the list of Ids of the geometry scoped in MyNS1 and MyNS2:

  for NS in NamedSelections.Children:
      if NS.Name=="MyNS1":
          MyIds1=NS.Ids
      if NS.Name=="MyNS2":
          MyIds2=NS.Ids
  MyIds3=MyIds1+MyIds2

Lastly, let's assign the list MyIds3 to the scoping of MyNS3:

  temp_sel=ExtAPI.SelectionManager.CreateSelectionInfo(SelectionTypeEnum.GeometryEntities)
  temp_sel.Ids=MyIds3
  MyNewNS.Location=temp_sel
