PDES, Inc. Celebrates its 25th Anniversary in 2013!
PDES, Inc. will celebrate its 25th Anniversary in August 2013. Formed in 1988 as a member-supported consortium, PDES, Inc. has grown to 26 members from industry, government and academia around the globe. This international consortium has committed tens of thousands of resource hours to projects that have accelerated the development and implementation of product data standards. Over the last three decades, PDES, Inc. has been instrumental in the publication of ISO 10303 Manufacturing Standards (STEP), including parts AP 203, AP 209, and AP 210. Today AP 203, Configuration controlled 3D design, which is supported by many CAD systems for import and export, is still a critical part of STEP. The LOng Term Archiving and Retrieval (LOTAR) International Project, an affiliated, international PDES, Inc. project, published six new standards through the Aerospace Industry Association (AIA) and the National Aerospace Standards (NAS) organization in the NAS9300 series. These LOTAR standards have enabled the packaging of data and information for enterprise reuse and repurpose applications as well as enabling data exchange between products. Other significant milestones over the last few years have included:
SCRA Applied R&D’s PDES, Inc. consortium announced the annual Bryan K. Martin Technical Excellence Award winner. The 2013 award was presented to Alain Roche of Dassault Systèmes at the Spring PDES, Inc. offsite meeting held in Gaithersburg, MD in May.
Roche has been involved in the testing of ISO 10303 (STEP) since 1999 and joined the LOng Term Arching and Retrieval (LOTAR) project in its early stages. He has added tremendous value as a technical leader and contributor and is a key contributor to the Recommended Practices published by the CAx-IF to aid other STEP implementers in their endeavors. Roche regularly assists other participants in clarifying technical issues and has played a leading role in many of the successful efforts to extend the STEP manufacturing standard.
Roche, a renowned expert for the implementation of STEP in many areas, carries considerable weight with the user community when evaluating the feasibility of new requirements. Dr. Michael R. Jahadi, President and Chairman of the PDES, Inc. Executive Board said, “Roche is one of the key contributors to the CAx-IF and that Roche’s technical expertise and leadership in proposing new technologies for STEP have set an example for the entire PDES, Inc. team.”
The PDES, Inc. Executive Board established the Bryan K. Martin Technical Excellence Award in memory of Bryan K. Martin, whose exceptional record of strong leadership and tireless work helped to achieve PDES, Inc. goals. The Board presents this award annually to a PDES, Inc. member who has demonstrated superior technical contributions to the program.
General Manager's Updates
As work began on last year’s (FY13) Technical Development Plan (TDP), the PDES, Inc. Executive Board recommended that a fresh look be taken at what drives projects and how the membership value of the projects is defined. To that end, an Executive Board Working Group (EBWG) was chartered to review the drivers and definition of projects. Dr. Howard Harary, from NIST, undertook the creation and leadership of that working group almost a year ago. At the May 2013 Board meeting the EBWG’s work was briefed, and Board approval was requested to adopt the team’s recommendations as the baseline for determining PDES, Inc. project acceptability. That approval was granted and the FY14 TDP, currently under development, will be aligned with those requirements. (See the figure below; click on figure for full-size version.)
The value of being a PDES, Inc. member is twofold: to leverage international research and development (IR&D) in a pre-competitive collaborative environment and to extract best methods that can be directly applied to improve business and technical performance. I believe that this new project planning framework enhances the delivery of both of those components of value.
The PDES, Inc. Board thanks Dr. Harary and his team for delivering an improved structure to align and define projects for inclusion in our TDP.
Computer-Aided x Implementor Forum (CAx-IF)
The CAx Implementor Forum (CAx-IF) is a joint testing effort between PDES, Inc. and ProSTEP iViP. The objective of the forum is to accelerate CAx/STEP translator development and ensure user requirements are satisfied by the STEP Standards. Now in its 14th year, the CAx-IF is conducting its 32nd round of testing. The scope for this round includes:
In preparation for this round of testing, the Forum participants have been updating recommended practices documents for PMI representation and presentation, geometric and assembly validation properties, and composite materials. Additionally, a new test suite document was developed for this round.
A recent accomplishment of the Forum is the development of the on-line Implementation Coverage tool. This tool not only allows users to ascertain the STEP functionality supported by their Computer Aided Design system provider, but to also compare the common functionality implemented by two systems.
Managed, Model-Based 3D Engineering
What do planes, trains and automobiles have in common? Regardless of original design tool, their product data can be exchanged using the ISO manufacturing standard, ISO 10303:242 Application Protocol: managed, model-based 3D engineering data (AP242). The AP242 standard is a merging of two of the most widely used manufacturing standards: AP203 configuration controlled design; and AP214 automotive design.
AP242 contains new capabilities not found in either of the original application protocols and is closely aligned with the tolerancing standards. The modular architecture used to develop the standard allows capabilities to be refined or even added more easily. To ensure usability, the standard is actually tested during development by the CAx-IF.
AP242 is the first ISO 10303 manufacturing standard to contain a business object model. The purpose of the business object model is two-fold. First, it is better suited for communication with domain experts in aerospace, defense and automotive domains because it is created using the vocabulary of these experts. Second, it also facilitates the development of Application Programmer Interfaces (APIs) to allow implementations of the standard to be developed for appropriate platforms.
AP242 can be used to define any complex or simple product for the automotive, aerospace, and rail industries, and even consumer products and ship building. The following list provides an overview of some of the business drivers behind the development of the standard.
