I´m trying to write a python script for set up Named Selection

My first try is the following short script:

sel=DataModel.Project.Model.AddNamedSelection()

sel.ScopingMethod=GeometryDefineByType.Worksheet

sel.Name="Groove Edges"

CRC=sel.GenerationCriteria

CRC.Add(None)

CRC[0]=Ansys.ACT.Automation.Mechanical.NamedSelectionCriterion()

CRC[0].Action=SelectionActionType.Add

CRC[0].EntityType=SelectionType.GeoEdge

CRC[0].Criterion=SelectionCriterionType.NamedSelection

CRC[0].Operator=SelectionOperatorType.Equal

CRC[0].Value=ExtAPI.DataModel.Project.Model.NamedSelections.Children[3]

sel.Generate()

It generate a new Named Selection from the NS list.

But I want to set the value to a name like "NS_Edge_groove_01".

Can someone help?

so instead of using:
CRC[0].Value=ExtAPI.DataModel.Project.Model.NamedSelections.Children[3]
you want to use Named selection name "NS_Edge_groove_01"
then you can loop through all the Model.NamedSelections.Children using a for loop and check the name of each named selection and once you find required namedselection, just use that in the value.
or
you can use the helpers available in the console:
DataModel.GetObjectsByName("NS_Edge_groove_01")[0] #so basically same for loop logic above, just using a single API method
and then
CRC[0].Value=DataModel.GetObjectsByName("NS_Edge_groove_01")[0]
hope that helps!

Hi
thanks for the hint. It works!

sel=DataModel.Project.Model.AddNamedSelection sel.ScopingMethod=GeometryDefineByType.Worksheet
sel.Name="Test"
CRC=sel.GenerationCriteria

CRC.Add(None)

CRC[0]=Ansys.ACT.Automation.Mechanical.NamedSelectionCriterion CRC[0].Action=SelectionActionType.Add
CRC[0].EntityType=SelectionType.GeoEdge
CRC[0].Criterion=SelectionCriterionType.NamedSelection
CRC[0].Operator=SelectionOperatorType.Equal
CRC[0].Value=ExtAPI.DataModel.GetObjectsByName("NS_Edge_Nut-1")[0]

CRC.Add(None)
CRC[1]=Ansys.ACT.Automation.Mechanical.NamedSelectionCriterion CRC[1].Action=SelectionActionType.Add
CRC[1].EntityType=SelectionType.GeoEdge
CRC[1].Criterion=SelectionCriterionType.NamedSelection
CRC[1].Operator=SelectionOperatorType.Equal
CRC[1].Value=ExtAPI.DataModel.GetObjectsByName("NS_Edge_Nut-2")[0]

CRC.Add(None)
CRC[2]=Ansys.ACT.Automation.Mechanical.NamedSelectionCriterion CRC[2].Action=SelectionActionType.Add
CRC[2].EntityType=SelectionType.GeoEdge
CRC[2].Criterion=SelectionCriterionType.NamedSelection
CRC[2].Operator=SelectionOperatorType.Equal
CRC[2].Value=ExtAPI.DataModel.GetObjectsByName("NS_Edge_Nut-",i)[0]

sel.Generate


One more question. How can I access to the named selection list? I want to filter only some ns with a similar name:
typical example in python:
mylist = ['face-1','face-2','face-3','face-4','edge-2','edge-1']
search = [s for s in mylist if "edge" in s]
print (search)

Hi

There are many ways of doing something like this, and below is just one way (the filtered named selection names are in the list edgename):
nslist=ExtAPI.DataModel.Project.Model.NamedSelections.Children

filterstr="edge"

edgename=[]

for ns in nslist:

sch=ns.Name.Split('-')

if sch[0]==filterstr:

edgename.append(ch.Name)

or

nslist=ExtAPI.DataModel.Project.Model.NamedSelections.Children
filterstr="edge"
edgename=[]
for ns in nslist:
if filterstr in ns.Name:
edgename.append(ns.Name)


All the best
