4.4.1.2 Element Decomposition

Provision of an aggregation structure where the element, representing the composite, is decomposed into parts represented by other elements.

The composite then provides, if such concepts are in scope of the Model View Definition, exclusively the following:

• Product Placement — the common object coordinate system to which the parts are placed relative

By default the following constraints apply to an element being decomposed by Element Decomposition:

• Body Geometry — composite is constructed from the sum of the Body Geometry of the parts;
• the composite shall not have an own Body Geometry, body geometry is provided at the parts;
• the composite shall not have an own Material assignment, material is assigned to the parts.

NOTE  Use the sub template Element Decomposition Required if any instance of the element is required to represent a composite with declared parts.

Figure 28 illustrates an instance diagram.
