Figure 11: Model: UML2 composite structure diagram of the monochromator assembly

Corresponds roughly to the view from above (the UML diagram can only at best indicate topology, not geometry).

Note also the lack of direction on the typed 'rotates with' and 'is mounted inside' connections compared with the "directed" association names. Compare with the «fitted» and «mounted» Dependencies, which emphasise the time order of construction (assembly) of the components, i.e., that the supplier must exist before the client.
