About US PRO
U.S. Product Data Association (US PRO)
The U.S. Product Data Association (US PRO) was a nonprofit
membership organization established by industry in 1992 and active
through December 31, 2006. US PRO provided the management functions for
the IGES/PDES Organization (IPO) and its related activities, including
the U.S. Technical Advisory Group (TAG) to ISO TC184/SC4. US PRO was
accredited by the American National Standards Institute (ANSI) to
support the development, publication, and distribution of the IGES and
PDES standards in the U.S. To facilitate these activities, US PRO
coordinated and managed multiple standards meetings in the U.S. each
Membership in US PRO was open to organizations that participated in activities sponsored by US PRO, the IGES/PDES Organization, the U.S. TAG to ISO TC184/SC4, and the various national product data exchange user groups. Membership contributions supported the operation of all programs and activities sponsored by US PRO.
The US PRO consortium was managed by the Advanced Technology Institute from 1997 until US PRO closed as a corporation in 2006. ATI builds international consortia to develop and implement innovative solutions for manufacturing, aerospace, automotive, maritime, metals, and healthcare industries. A private, non-profit research corporation with principle operations in Charleston, SC, ATI is an affiliate of SCRA.
US PRO's primary activities included hosting the ISO/IPO standards development meetings held in the U.S. each year, support for the U.S. TAG as required to maintain accreditation with ANSI, publication and distribution of the standards documents developed and approved as a result of these activities, as well as education and training, marketing, and communications efforts. These activities served both U.S. industry and government agencies by providing a national forum for participation by all interested parties from industry, government, and academia.
"Participation in US PRO is an investment in the development and
use of product data exchange technology in the United States. This
commitment helps ensure that U.S. industry remains competitive in the
U.S. TAG to ISO TC184/SC4
US PRO managed the U.S. Technical Advisory Group to ISO Technical Committee 184, Sub-Committee 4 from 1997 through March 31, 2007. This responsibility was transitioned to the Electronic Commerce Code Management Association (ECCMA) effective April 1, 2007. For more information, please see the U.S. TAG website or contact the TAG Administrator.
IGES/PDES Organization (IPO)The IGES/PDES Organization (IPO) was a program area of US PRO. The IPO General Assembly functioned as the U.S. body of individuals from industry, government, and academia dedicated to the development of standards and technology for the exchange of product information. Work was focused on two projects, the Initial Graphics Exchange Specification (IGES) and Product Data Exchange using STEP (PDES).
The IPO was created in the late 1970s to develop a neutral file format for the exchange of geometric data among different CAD systems. From this effort IGES was first published in 1980, and IGES Version 5.3 was published in 1996 as an ANSI standard. A second generation PDE technology, Product Data Exchange Specification (PDES), was initiated during the mid-1980s. Submitted to ISO in 1988, it was adopted as the basis for ISO 10303 (STEP) by the international community.
Product Data Exchange using STEP (PDES)
Product Data Exchange using STEP (PDES) is an adoption of the
International Standard for the Exchange of Product Model Data (STEP).
STEP has been approved by more than 20 countries worldwide including
all major U.S. trading partners.
The Initial Graphics Exchange Specification (IGES)
The Initial Graphics Exchange Specification (IGES) defines a neutral
data format that allows for the digital exchange of information among
computer-aided design (CAD) systems. CAD systems are in use today in
increasing numbers for applications in all phases of the design,
analysis, manufacture and testing of products. Since it is common
practice for a designer to use one supplier’s CAD system and for the
contractor and subcontractors use different systems, there is a need
for the ability to exchange data digitally among all CAD systems.
The latest available draft if IGES 6.0 (1999-01-12) has been renamed by its developers as IGES 5.x, and it is available for download as a hyperlinked 4.3MB PDF file with color figures from http://www.iges5x.org/archives/version5x/. The Wikipedia provides a definition of IGES and another link to IGES 5.x: http://en.wikipedia.org/wiki/IGES.
