Can I check why is it that when I run this code, it over-calculates the wall area such that it calculates wallarea that extends above the ceiling as shown in the picture (I only want to calculate the interior wall area of level 1 room but it extends to level 2 (as shown in the faint orange mark)?

calculator = SpatialElementGeometryCalculator(doc,opt)

if calculator.CanCalculateGeometry(room):
results = calculator.CalculateSpatialElementGeometry(room)
roomSolid = results.GetGeometry()
roomFaceLst = []
for face in roomSolid.Faces:
for spatialSubFace in results.GetBoundaryFaceInfo(face):
if spatialSubFace.SubfaceType != SubfaceType.Side:
continue
element = doc.GetElement(spatialSubFace.SpatialBoundaryElement.HostElementId)

if isinstance(element, Wall):
if elementType.Kind == WallKind.Curtain:
continue
roomFaceLst.append(face.ToProtoType()[0])
totalroomFaceLst.append(roomFaceLst)
else:
output.append("cannot calculate element geometry")
OUT = totalroomFaceLst[selection]
