- my_NS = ExtAPI.DataModel.GetObjectsByName('Casing')[0]
- geodata = ExtAPI.DataModel.GeoData
- area = 0
- my_id = 0
- for face_id in my_NS.Ids:
- if geodata.GeoEntityById(face_id).Area >area:
- area = geodata.GeoEntityById(face_id).Area
- my_id = face_id
- print('Face Id is: ' + str(my_id) + ' and area is: ' + str(area))

You can also use a python sort method on a list and sort on the Area property. Then look at the last in the list. This is less coding and probably faster than a for loop.

One way to go could be:
- my_NS = ExtAPI.DataModel.GetObjectsByName('Casing')[0]
- geodata = ExtAPI.DataModel.GeoData
- face_tuples = [(geodata.GeoEntityById(face_id), geodata.GeoEntityById(face_id).Area) for face_id in my_NS.Ids]
- sorted_faces = sorted(face_tuples, key=lambda face: face[1])
- print('Face Id is: ' + str(sorted_faces[-1][0].Id) + ' and area is: ' + str(sorted_faces[-1][1]))

@Mike.Thompson
Please teach me the specific method you just told me.
I don't want just the largest area, but I want to get up to the second largest one.0 -
Thank you, I was able to do it with the method you taught me
