Application module: Physical component feature | ISO/TS 10303-1721:2018-11(E) © ISO |
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:

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.
