# Bond Create

Currently bonds cannot be created automatically from inside a file, using either the geometric Length or the topological Delaunay methods. Each bond object contains thus a complete description of one bond only.

To specify the atoms forming the bond, the bond parameters parent1, parent2 must point to the atom id attributes, which are different for each atom.

    Example: <bond ... parent1="C1" parent2="C2"/> (no default)
    Allowed values: alphanumeric expression representing a unique atom id
    with less than 20 characters (defined in GAMGI_ENGINE_TOKEN) (required)
