My objective was to find a way to transfer Named Selections from a model to another model, never managed to find it. Thanks to Erik code I could finally create something that works, which I share below and hope it's useful for someone.

FILE_NAME = 'named_sel_export.py'

model = ExtAPI.DataModel.Project.Model

object_lists = {
    # 'Ansys.ACT.Automation.Mechanical.AnalysisPly': 'model.???',
    # 'Ansys.ACT.Automation.Mechanical.CrossSection': 'model.???',
    'Ansys.ACT.Automation.Mechanical.Material': 'model.Materials.Children',
    'Ansys.ACT.Automation.Mechanical.NamedSelection': 'model.NamedSelections.Children',
    'Ansys.ACT.Automation.Mechanical.CoordinateSystem': 'model.CoordinateSystems.Children',
}

with open(FILE_NAME, 'w') as f:
    lines = []
    lines.append("def get_entity_by_name(entity_list, name):")
    lines.append("    for x in entity_list:")
    lines.append("        if x.Name == name:")
    lines.append("            return x")
    lines.append("    return None")
    lines.append("")
    lines.append("model = ExtAPI.DataModel.Project.Model")
    lines.append("")
    for ns in model.NamedSelections.Children:
        lines.append("ns = Model.AddNamedSelection()")
        lines.append("ns.Name = '{}'".format(ns.Name))
        lines.append("ns.ScopingMethod = GeometryDefineByType.{}".format(ns.ScopingMethod))
        if ns.ScopingMethod == GeometryDefineByType.Worksheet:

            for i, criteria in enumerate(ns.GenerationCriteria):

                if criteria.Action in [SelectionActionType.Invert, SelectionActionType.Convert]:
