    Given a (multi)geometry, returns a (multi)geometry consisting only of elements of the specified type. Sub-geometries that are not the specified type are ignored. If there are no sub-geometries of the right type, an EMPTY geometry will be returned. Only points, lines and polygons are extracted.
    
    Parameters:
    
    geometry -
    
    dimension -
    
    Returns:
    
    Throws:
