4.2.468 Shape_element

A Shape_element is a portion of shape that has to be identified explicitly to be associated with other information.

EXAMPLE In order to identify a portion of one face of a shaft that shall have a surface coating applied to it, Shape_element is used. Figure 66 shows this example.

NOTE 1 Shape_element objects can be classified using General_classification.

EXAMPLE An example for classifying Shape_element objects is to identify all parts of an air plane that constitute the outer surface of the plane and are therefore relevant for aerodynamic analysis.

NOTE 2 If the Shape_element is referenced by a Size_dimension as is_applied_to the Shape_element is on the physical boundary of the Item_shape.

Each Shape_element may be a Coating_layer or a Feature_occurrence.

The data associated with a Shape_element are the following:

4.2.468.1 composition

The composition specifies the shape that the Shape_element is part of.

See shape_element to item_shape for the application assertion.

4.2.468.2 description

The description specifies additional information about the Shape_element.

See shape_element to multi_language_string for the application assertion.

The description need not be specified for a particular Shape_element.

If present, there shall be exactly one object that defines the description for a Shape_element.

4.2.468.3 element_name

The element_name specifies the word or group of words by which the Shape_element is referred to.

The element_name need not be specified for a particular Shape_element.
