General sizes: Objects know their default size. But that can be changed with either explicit sizes (e.g., "3 feet tall") or non-specific sizes (e.g., "large", "huge", "small", etc.).
Orientation:Objects can face in different directions. The direction can be specfied as left, right, forwards, backwards, east, west, up, down, north, south, northeast,...
Directions are relative to the default viewing position. If you move the viewpoint, the directions don't change meaning. In some instances, however, directions will be relative to object position.
