Hello,

First time in this forum. I want to do a script that associates a part geometry from the Geometry tree to a named selection. It looks auite simple at first sight.

Here's my script.

model = ExtAPI.DataModel.Project.Model    
geom = model.Geometry
selection_manager = ExtAPI.SelectionManager

for part in geom.Children:
    bodyName = body.Name

    selection_manager.ClearSelection()
    selection = ExtAPI.SelectionManager.CreateSelectionInfo(SelectionTypeEnum.GeometryEntities)
    
    selection.Ids = [part.ObjectId]                                          ! at this point, I associate my part ID to the selection
    selection_manager.NewSelection(selection)

    new_namedSelection = model.AddNamedSelection()
    new_namedSelection.Name = 'b_'+body.Name   

    new_namedSelection.Location.Ids= selection.Ids           ! HERE IS THE PROBLEM         

The problem here is that if I do a print(selection.ids), I'll get the Id associated to the part I want the named selection to be associated to. So far so good. But if I do a print(new_namedSelection.Name.Location.Ids), I'll get an empty list, when it should be a one-item list with the Id I'm interested in.

I don't understand why the last line does not work properly.

 

Thank for your time

Hi Erik,

 

The GetGeoBody() was what I was missing. It worked. 

 

Thanks

[Erik Kostson]

Yes we need the body id to define the NS. Great that it worked. Erik

However, is there a method  similar to NamedSelection.Location.Ids that gets the ids of the nodes associated to the name selection geometry, instead of the ids of the geometric entities?

 

Thanks in advance
