def Geo_list():
geo_list=[]
for geoid in ExtAPI.SelectionManager.CurrentSelection.Ids :
geoEntity = DataModel.GeoData.GeoEntityById(geoid)
geo_list.append(geoEntity)
return geo_list

for geo in Geo_list():
Print(geo.Area)

all_named_selections = ExtAPI.DataModel.GetObjectsByType(Ansys.ACT.Automation.Mechanical.NamedSelection)
for ns in all_named_selections:
    print "named selection: {}".format(ns.Name)
    entities = ns.Entities
    for entity in entities:
        print "  entity: {}".format(entity.Id)
        print "    area: {}".format(entity.Area)
        print "    centroid: {}".format(entity.Centroid)

Note: Depending on the type of the entity that is in the named selection (body, face, edge, vertex, node, element, or element face), the last two lines of the above code may behave differently. This version was tested using a face Named Selection.

Hi @ZZ.tang , the code you shared will work on the active selection in Mechanical, not on a named selection. For it to work on a named selection, the principle will be the same:

access the named selection (for example by its name)
check the ids of the entities scoped in that NS
use GeoData to obtain information on the geometry
