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;

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

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.
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.
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;
(*
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.
