JT data format gains ISO acceptance

Siemens PLM Software’s JT data format has been accepted as the world’s first ISO international standard for viewing and sharing lightweight 3D product information data in product lifecycle management (PLM). Karen McCandless finds out more

Siemens’ JT data format is a lightweight data format that allows companies to view and share digital 3D product information in real time throughout all phases of the product’s lifecycle.

The PLM industry’s most widely used 3D visualisation format, it enables collaboration and visualisation at the scale required by industry.

Simon Floyd, director, innovation and product lifecycle management solutions at Microsoft, said: “You’ve heard the saying ‘A picture tells a thousand words,’ well in the context of design and manufacturing, you could say ‘3D answers your questions.’ JT provides the ability to share 3D content easily and allows people to collaborate effectively.”

Mike Zink, senior product manager at Siemens PLM Software, added: “The importance of JT achieving International Organization for Standardization (ISO) acceptance is visible through users being able to own their data. When collaborating on a global scale, they need access to relevant information in real time to make complex product decisions without being constrained by proprietary CAD formats.”

Now that JT is a standard, anyone can implement the standard to suit their needs, whether they wish to simply provide a solution or ensure a degree of independence and protection

The JT format is supported by the JT Open Program, a community of corporate software users and vendors that share JT knowledge and influence its direction. They also encourage widespread adoption in the industry.

ProSTEP iViP is an international association committed to developing innovative approaches to solving business problems and promoting modern standards. It is also a JT Open Program supporter and worked with Siemens to get JT approved by ISO as an international standard.

“Leaders in the JT Open Program agreed that the only way to truly confirm JT as the common open solution for 3D visualisation and collaboration was to get it recognised by ISO,” said Zink.

The company went through the fast-track harvesting procedure on advice from JT Open Program members. Harvesting allows companies to skip a number of stages if the material is mature.

“ISO IS14306 provides a detailed and comprehensive description of the JT data format, enabling companies to further leverage JT in their PLM workflows and software applications,” said Zink. “ISO adoption provides a benchmark for open access and enables industry leaders to have open access to shared data, to facilitate collaboration and innovation and enable reuse of data. Other 3D formats have been promoted in the industry but none have achieved the same level of acceptance.”

Floyd commented on the significance of this decision: “It’s absolutely vital for long data retention. Manufacturers need the security of being able to read their documents, 3D or otherwise, at all times, irrespective of changes in software or systems in the future. Now that JT is a standard, anyone can implement the standard to suit their needs, whether they wish to simply provide a solution or ensure a degree of independence and protection.”
