   .. py:method:: index() -> int
                  index(unset_index_value: int) -> int

      Value of the runtime model component index attribute.

      :param unset_index_value: Value to return if the index has not been set.
                                ``ON_UNSET_INT_INDEX`` or indices of default components are often
                                used for this parameter.
      :type unset_index_value: int

      .. rubric:: Notes

      If the component is in a model, then the index is unique for all
      components of identical type in the model and is locked. If the index
      has not been set, ``unset_index_value`` is returned. The
      ``index()`` value can change when saved in an archive (.3dm file).
      Use the `get_uuid()` when you need to reference model components in an
      archive.
