Application module: Component feature | ISO/TS 10303-1657:2019(E) © ISO |
This clause specifies the EXPRESS schema derived from the mapping table. It uses elements from the common resources or from other application modules and defines the EXPRESS constructs that are specific to this part of ISO 10303.
This clause constitutes the Module Interpreted Module (MIM) of the application module.
This clause also specifies the modifications that apply to the constructs imported from the common resources.
The following restrictions apply to the use, in this schema, of constructs defined in common resources or in application modules:
Short names of entities defined in this schema are described in Annex A. Unambiguous identification of this schema is defined in Annex B.

This subclause specifies the MIM type for this application module. The MIM 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.
