ISO 10303-214:2010(E)
A Compound_feature_in_solid_element is the identification and, if necessary, the positioning of an element of a Compound_feature_in_solid.
If the Compound_feature_in_solid_element is a Thread_feature, there shall be a Compound_feature_in_solid_element_relationship that references the Compound_feature_in_solid_element representing the Thread_feature as successor and a Compound_feature_in_solid_element referring to either a Circular_boss or a Round_hole as predecessor.
The data associated with a Compound_feature_in_solid_element are the following:
The element_placement specifies the geometric Transformation that defines the position and the orientation of the Compound_feature_in_solid_element in the coordinate space of the Compound_feature_in_solid, in the case where the Compound_feature_in_solid is applied as a Placed_feature. The element_placement shall not be used if the Compound_feature_in_solid_element is a Thread_feature or a Transition_feature. In the case where the Compound_feature_in_solid is applied as an Included_feature, the element_placement shall not be instantiated.
See compound_feature_in_solid_element to transformation for the application assertion.
The element_placement need not be specified for a particular Compound_feature_in_solid_element.
The feature specifies the Process_feature_in_solid that is the feature definition of the Compound_feature_in_solid_element.
See compound_feature_in_solid_element to process_feature_in_solid, compound_feature_in_solid_element to thread_feature, and compound_feature_in_solid_element to transition_feature for the application assertions.
There shall be exactly one object that defines the feature for a Compound_feature_in_solid_element.
The is_element_for specifies the Compound_feature_in_solid_element of which the Compound_feature_in_solid_element is a component.
See compound_feature_in_solid_element to compound_feature_in_solid for the application assertion.
