ISO 10303-214:2010(E)
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:
The composition specifies the shape that the Shape_element is part of.
See shape_element to item_shape for the application assertion.
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.
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.
