entityId ObjectId: ObjectId of the entity acting as a region.
midOrdinate Double: The default mid-ordinate length used to get region from the entity. If the selected object contains arc segments, each segment is tessellated into chord segments. The length of each chord segment is derived from the specified mid-ordinate distance.
