Siemens sets standard for 3D data format

Veronica C. Silva | Jan. 7, 2013
Siemens JT data format has been recognised by ISO.

Siemens has recently set an international standard for viewing 3D data for sharing and viewing in real time.

Siemens said its JT data format has been accepted by the International Organization for Standardization or ISO for viewing and sharing lightweight 3D product information.

Siemens said the new standard can be used for computer-aided design (CAD) and all phases of the product lifecycle management (PLM). As an international standard, users of the JT format will no longer be dependent on proprietary formats, thus making it easier for them to collaborate, said Siemens.

The JT format has already won the approval of General Motors, which uses it for 3D design and other aspects of its business.

PLM strategy

Nick Bell, CIO, Global Product Development, General Motors, said they have been using the JT file format for more than a decade now and is part of their PLM strategy.

"JT allows our team to easily communicate design data across the enterprise and our supply chain, improving our ability to communicate and collaborate visually. For this reason, we are very pleased to see JT finally recognised as an ISO International Standard," added Bell.

The JT format was developed by Siemens PLM Software, a business unit of the Siemens Industry Automation Division. Siemens said JT has been used by the industry as an open format for 3D data sharing and "has become a common language for 3D collaboration in PLM."

"The acceptance of JT as an ISO standard will further accelerate its adoption, thereby improving product development productivity and efficiency for the global manufacturing industry. Today's announcement is a historic milestone for PLM open standards and further reinforces Siemens' overall commitment to an open business model that benefits the entire industry," said Chuck Grindstaff, CEO and president, Siemens PLM Software.


Siemens worked closely with ProSTEP iViP, a global consortium committed to advancing open standards, to complete the process of gaining ISO approval. 

With the help of ProSTEP iViP, the JT File Format Reference document was published as a Publicly Available Specification (ISO PAS 14306) in October 2009, paving the way for it to be an international standard. The document details and describes the JT data format to help organisations and software vendors to use JT in their PLM workflow and software applications. JT acceptance was coordinated through TC 184 / SC4, the ISO body responsible for Industrial Data, through a global ballot process, said Siemens.

"As a recognised leader in guiding the development of standards for industry, ProSTEP iViP is pleased to have JT achieve the status of International Standard. The need for a globally accepted lightweight 3D data definition has now been met. Standards offer industry a path towards consistent software implementations and JT's new status reinforces its role in that effort," said Dr. Steven Vettermann, general manager, ProSTEP iViP.
