This clause specifies the information requirements for the
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
Component_feature_arm
schema and identifies the necessary external references.
EXPRESS specification:

This subclause specifies the ARM type
for this application module. The ARM type and
definition is specified below.
The cf_groupable_item type is an extension
of the
groupable_item type.
It adds the data
type
Component_feature
to the list of alternate data types.

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 Component_feature is a type of
Shape_element
The location of the Component_feature in the assembly model is derived from the placement of the associated_definition
in the assembly model and the placement of the definition model in the
derived_from
model of that associated_definition.
EXPRESS specification:

END_ENTITY;
(*
Attribute definitions:
definition:
the
General_part_feature
that serves as a definition for the Component_feature.
The value of this attribute need not be specified.
associated_definition:
the
Assembly_component
that has the
Component_feature.
NOTE
The subtypes of Component_feature specify specializations of
Assembly_component
that are consistent with the subtype of definition.
product_definitional:
a Component_feature is always definitional.
Formal propositions:
UR1:
The combination of definition and associated_definition shall be unique within a population of Component_feature.
UR2:
The combination of
element_name
and associated_definition shall be unique within a population of Component_feature.
A Component_feature_joint is a type of
Component_feature_relationship
and of
Shape_element
for the representation of a joint between two
Component_features.

Attribute definitions:
feature_1:
specifies one role of the
Component_feature
for the Component_feature_joint.
feature_2:
specifies another role of the
Component_feature
for the Component_feature_joint.

Assembly_definition
to which the Component_feature_joint belongs.
Formal propositions:
WR1:
the feature_1 and feature_2 shall not point to the same instance of
Component_feature.

the
Component_feature
referenced by feature_1 shall be used by the same
Assembly_definition

Component_feature
referenced by feature_2 shall be used by the same
Assembly_definition
as the associated_definition.
A Component_feature_make_from_relationship is a type of Component_feature_relationship.
A Component_feature_make_from_relationship is an association
between two Component_feature, where one
Component_feature is used as a basis for the development of another Component_feature.
EXPRESS specification:
