Siemens PLM Software said the JT data format is moving closer to becoming an ISO (International Organization for Standardization) standard.

Siemens and ProSTEP iViP, a global consortium promoting open standards, said they had initiated the formal process to make JT an ISO standard for lightweight 3D data.

Lightweight 3D data are a subset of data created by computer aided design (CAD) software applications. When the lightweight format is open and widely adopted, this would more easily allow the use of these data across applications.

“JT as an open visualization standard will expand the usage of 3D data into several process areas outside engineering design, and will open a window of significant opportunities for independent software vendors to provide advanced IT solutions based on JT,” said Alfred Katzenbach, director engineering IT at Daimler and head of the product lifecycle management (PLM) working group of Germany’s automobile association, the VDA.

Katzenbach said in a statement, that more applications would be available to work seamlessly within open environments, which would free users from the closed systems of a single vendor.

“This is a significant reason why the international automotive OEMs are fully committed to JT ISO standardization,” Katzenbach said.

Siemens PLM has published an updated JT file format specification. This version 9.5 will be brought forward through the ISO process as the new standard.
