ISO 10303-214:2010(E)
A Process_operation_input_or_output is the input or expected result of a Process_operation_definition.
The data associated with a Process_operation_input_or_output are the following:
The concerned_shape specifies the set of Shape_element objects that are affected by the Process_operation_occurrence.
See process_operation_input_or_output to shape_element for the application assertion.
The description specifies additional information about the Process_operation_input_or_output.
See process_operation_input_or_output to multi_language_string for the application assertion.
The description need not be specified for a particular Process_operation_input_or_output.
If present, there shall be exactly one object that defines the description for a Process_operation_input_or_output.
The element specifies the element that plays the role of the input or the output for the operation.
See process_operation_input_or_output to assembly_component_relationship, process_operation_input_or_output to design_discipline_item_definition, process_operation_input_or_output to item_instance, and process_operation_input_or_output to mated_item_association for the application assertions.
There shall be exactly one object that defines the element for a Process_operation_input_or_output.
The operation specifies the Process_operation_occurrence that the Process_operation_input_or_output is associated with.
See process_operation_input_or_output to process_operation_occurrence for the application assertion.
The placement specifies the geometrical Transformation between the local coordinate system of the element acting as Process_operation_input_or_output, and the reference coordinate system. The reference coordinate system is either the coordinate system of the reference tool, if present, for the concerned Process_operation_occurrence or, if no reference tool is present, the coordinate system of the Process_operation_occurrence itself.
See process_operation_input_or_output to transformation for the application assertion.
The placement need not be specified for a particular Process_operation_input_or_output.
The role specifies whether the identified element plays the role of an input or an output for the operation.
