4 Information requirements

This clause specifies the information requirements for the Physical component feature application module. The information requirements are specified as the Application Reference Model (ARM) of this application module.

NOTE 1  A graphical representation of the information requirements is given in Annex C.

NOTE 2  The mapping specification is specified in 5.1. It shows how the information requirements are met by using common resources and constructs defined or imported in the MIM schema of this application module.

This clause defines the information requirements to which implementations shall conform using the EXPRESS language as defined in ISO 10303-11. The following begins the Physical_component_feature_arm schema and identifies the necessary external references.

EXPRESS specification:

*)
SCHEMA Physical_component_feature_arm;
(*

4.1 Required AM ARM

The following EXPRESS interface statement specifies the elements imported from the ARM of another application module.

EXPRESS specification:

*)
USE FROM Component_feature_arm;    --  ISO/TS 10303-1657
(*

NOTE 1   The schemas referenced above are specified in the following part of ISO 10303:

Component_feature_arm ISO/TS 10303-1657

NOTE 2   See Annex C, Figures C.1and C.2 for a graphical representation of this schema.

4.2 ARM entity definitions

This subclause specifies the ARM entities for this module. Each ARM application entity is an atomic element that embodies a unique application concept and contains attributes specifying the data elements of the entity. The ARM entities and definitions are specified below.

4.2.1 Physical_component_feature   EXPRESS-GMapping table

A Physical_component_feature is a type of Component_feature. The Physical_component_feature supports identification of physical features that are not otherwise identified in a component feature classification. Physical_component_feature is only applicable to physical assembly design views and is not applicable to interconnect design views.

NOTE 1   The Physical_component_feature is interpreted to be an aim entity Component_feature when no other information is provided in the aim population.

NOTE 2   The Physical_component_feature is not supporting embedded discrete components since the context of components in the implicit role of embedded discrete component is an interconnect view.

NOTE 3   The Physical_component_feature supports the specification of a Component_feature as a Datum_target or the specification that a Component_feature defines a Datum for the purpose of estabishing a datum reference frame for tolerance specification.

EXPRESS specification:

*)
ENTITY Physical_component_feature
  SUBTYPE OF (Component_feature);
END_ENTITY;
(*

4.2.2 Physical_component_terminal   EXPRESS-GMapping table

A Physical_component_terminal is a type of Component_terminal and a Physical_component_feature. A Physical_component_terminal is realized by a distinct feature on a discrete component.

NOTE    This part of ISO 10303 distinguishes between components and features that are discrete and those that are realized as part of a continuous fabrication process.

EXPRESS specification:

*)
ENTITY Physical_component_terminal
  SUBTYPE OF (Component_terminal, Physical_component_feature);
END_ENTITY;
(*
