Plane Panel Parts

As mentioned in the preceding paragraph the parts of a plane panel are normally implicitly stored in the panel and considered as part of the hull structure via the panel. (The circular reference arrows pointing back to the panel in the hull structure figure above indicate that the parts are (implicitly) stored in the panel "container".)

Panel brackets (see above) are the only separately stored parts in the hull structure in the model data bank.

When released for production parts are hardly considered as "model objects". However, it is always possible to reach the released part from the model object (=the panel) and in the opposite direction it is possible to find back from the part to the implicit part in the panel. Actually, some attribute information is never really copied to the released parts but is always fetched from the model via the part. This means that such information may be changed and still there is no need to extract the parts again.
