The Siemens JT data format has been accepted as the world's first ISO standard for the display and sharing of lightweight 3D product information. The data format allows for real-time viewing and sharing of 3D product information throughout all phases of the product lifecycle. JT enhances collaboration, as 3D product data can be seamlessly and instantly moved between any number of CAD and PLM software products. By standardizing the format, companies have the opportunity to organize their 3D data exchange also through JT. This is particularly interesting in multi-CAD environments.
What is JT
JT saves highly compressed facet information (triangles) as an exchange format. The so-called tessellation is used for this. This breaks down polygons into small parts. Attributes and CAD-specific nodes are also saved. Dr. Wallner looks at this topic in the training course large assamblies. The ISO IS14306 provides a detailed and comprehensive description of the JT data format and enables companies and software vendors to use the format in their PLM workflow or software applications.

History
JT was developed in its first version in 1998 by Hewlett Packard and Engineering Animation. Following the purchase of Engineering Animation by UGS (Unigraphics) in 1999 and the subsequent takeover of UGS by Siemens, the JT format is now part of the Siemens PLM Software division.
