ePLM Interoperability ASD Strategic Standardization Group

The objective of the “CAD 3D composite interoperability” working group is to ensure the coordination and the consistency of all ASD standardization activities related to “CAD 3D composite” information interoperability. This working group is part of the ASD SSG “PLM interoperability” domain.

The recommendations of the working group cover product information interoperability for the full life cycle of the CAD 3D composite structure development, from specifications to maintenance. It covers all the interoperability functions based on open standards, such as:

• integration between heterogeneous authoring applications (upstream, downstream, ...)
• communication with the extended enterprise or with the customers,
• visualization,
• long term archiving and retrieval,
• data quality,
• and migration.

The first version of this web page has a limited scope, and will be regularly updated.

Scope

Based on a generic product life cycle stage of Aerospace and Defence CAD 3D composite structures, the following figure describes the different Composite models with associated information characteristics.

Nota: Same figure than for the AIA – ASD Stan LOTAR “Electrical Harness” working group

List of use cases

The following table list the European A&D use cases to be supported by the international standards for CAD 3D composite interoperability.

Nota: for access to use cases for Long Term Archiving and retrieval, refer to the LOTAR “Composite” WG web page.

The 5 years vision of the ASD SSG “CAD 3D composite interoperability” working group is set up on three principles:

1) CAD 3D composite interoperability ensured by the availability of use cases, ISO information model, recommended practices and CAD vendors testing.

The operational use of Composite interoperability standards by the A&D industries requires the availability of:

• Use cases for Composite interoperability, supporting A&D business needs and priorities,
• International standards for Composite Information models (Cf. principle 2)
• International and/or European recommended practices based on use cases, detailing the implementation of the ISO Composite information model,
• Interoperability testing of the standardized Composite interfaces and services of the different PLM vendors, through the participation in the CAX Implementer Forum.

2) Reliable ISO Information models for CAD 3D Composite interoperability.

The ASD SSG recommends the choice of a limited number of core harmonized ISO 10303 Application Protocols, having interdependencies properly specified and managed through the time. As a result:

• STEP AP 203 “Configuration-controlled design”
• STEP AP 209 ” Composite & metal structural analysis & related design”,
• The ASD SSG has supported the convergence of STEP AP 203 and AP 214 in AP 242.

Planned operational use of ISO standards for Composite interoperability and long term archiving:

3) Contribution to the development and use of the NAS / EN 9300 3XX family, for Long Term Archiving and Retrieval of CAD 3D composite information.

The ASD SSG strategy relies on the joint AIA – ASD Stan LOTAR international project to develop the NAS / EN 9300-3XX standards for composite structures.

The LOTAR standard will define Process, use cases, validation and verification rules for long term archiving and retrieval of composite information.
