1 Scope
This part of ISO 13584 specifies a representation category called basic_geometry. This representation category captures the generic concepts of the shape of a part. This representation category may be associated with any of the items defined in a parts library. This part of ISO 13584 also defines how representations that belong to this representation category may be exchanged within a library exchange context by means of FORTRAN programs compliant with ISO 13584‑31:1999.
The following are within the scope of this part ISO 13584:
-
— the definition of the basic_geometryrepresentation category and the mechanisms to be used to reference it;
-
— the properties to be used to characterize a particular representation within the basic_geometryrepresentation category;
-
— the exchange format to be used for the library external files that describe the basic_geometry representations of classes of items described in a parts library by means of FORTRAN programs based on the application programming interface specified in ISO 13584‑31:1999;
-
— the mechanism to be used, by case of separate agreement between the sender and the receiver, to reference external files that describe the basic_geometry representations of classes of items described in a parts library by means of formats not specified in ISO 13584;
-
— the implementation resources to be supported on any implementation that claims conformance to this part of ISO 13584;
-
— the dictionary entries to be supported by any implementation that claims conformance to this part of ISO 13584;
-
— the standard data to be recognized by any implementation that claims conformance to this part of ISO 13584.
The following is outside the scope of this part of ISO 13584:
-
— the structure and exchange format of a library delivery file that includes references to the representation category defined in this part of ISO 13584, and/or to the library external files whose exchange format is specified.
NOTE 1 The structure of a library delivery file is defined by a library integrated information model specified in one of the logical resource series parts of ISO 13584.
NOTE 2 The ISO13584_f_m_iim_schema, documented in ISO 13584‑24, is a library integrated information model that defines the structure of a library delivery file. Such a library delivery file may contain instance values that reference the representation category and/or the library external files defined in this part of ISO 13584.
