# links
linked_docs = FilteredElementCollector(doc).OfCategory(BuiltInCategory.OST_RvtLinks).WhereElementIsNotElementType().ToElements()


# linked file
link_document = []

for link in linked_docs:
    link_doc = link.GetLinkDocument()
    link_document.append(link_doc)

link = link_document[0]

# walls
linked_walls = FilteredElementCollector(link).OfCategory(BuiltInCategory.OST_Walls).WhereElementIsNotElementType().ToElements()


faces_of_walls = []

for elem in linked_walls: #for every element
    edges = [] #an empty list for the edges to process
    processed = [] #the list of processed edges which we want to keep
    geos = elem.get_Geometry(Options()) #the geometry
    for geo in geos: #for every geometry found
        if geo.__class__ == DB.Solid: #if the geomtry is a solid
            faces = geo.Faces #get the faces
            for f in faces:
                faces_of_walls.append(f)

OUT = faces_of_walls

i think that code can also be a starting point. It return all faces of a wall, from walls in a linked file.
