ProSTEP iViP and Siemens PLM Software Initiate Process to Establish JT Data Format as ISO Standard

Supplier News

Siemens PLM Software  and ProSTEP iViP have initiated the formal process to establish the JT data format as an ISO standard for lightweight 3D data.  

Siemens PLM Software is a business unit of the Siemens Industry Automation Division and a leading global provider of product lifecycle management (PLM) software and services.  

ProSTEP iViP is a global consortium instrumental in advancing open standards.  

Speaking at the recent 2010 JT Open International Conference in Orlando, Florida, Dr. Steven Vettermann of the ProSTEP iViP Association said that the publication of the JT File Format Reference document as a Publicly Available Specification (ISO PAS 14306) in October 2009 was the first step towards becoming an International Standard.  

He added that ProSTEP iViP and Siemens PLM Software were working together to complete the process of gaining International Standard status for JT.   

Lightweight 3D data represents a subset of the more complete product data definition typically created by computer aided design (CAD) software applications.  

When the lightweight format is open and widely adopted, it extends the reach of information, traditionally locked in proprietary systems to applications such as Digital Mockup (DMU), simulation, design in context and simplified drawings.

The JT data format finds application in several industries and disciplines such as automotive, aerospace, defence, shipbuilding, mechanical and plant engineering among others, necessitating the need for standardising it.  

Prof. Alfred Katzenbach, Director Engineering IT at Daimler and head of the VDA working group PLM comments that JT as an open visualisation standard will expand the usage of 3D data into several process areas outside engineering design, opening a window of significant opportunities for independent software vendors to provide advanced IT solutions based on JT.  

He adds that more applications will be available to work seamlessly within open environments, freeing the user community from the closed systems of a single vendor.  

This is a significant reason why the international automotive OEMs are fully committed to JT ISO standardisation.  

ISO requires that new International Standards begin with the definition of a balloted New Work Item Proposal. The JT ballot was issued on August 24, 2010, and after review has been accepted as a new item that will be added to the program of work of the committee.  

To support the new work effort Siemens PLM Software has published an updated JT File Format Specification version 9.5 that will be brought forward through the ISO process as the new standard.  

In a joint statement to the JT Open Management Review Board, Jim Marchant and Jason Bilsland, who are responsible for visualisation data assets strategy at Rolls-Royce that has been using JT as a visualisation format for many years said that JT’s advent as a PAS helped them broaden the scope of potential usage of JT in their business.  

They also see the full adoption of JT as an ISO standard as further validation of their overall PLM strategy.  

Chuck Grindstaff, President of Siemens PLM Software says that they have committed to making JT an ISO standard at the ProSTEP iViP Symposium held in April 2010.  

He adds that having ProSTEP iViP take the lead in this effort is testament to the openness and wide-spread adoption of JT in the global manufacturing industry.
