The Siemens JT data format has been accepted as the world's first ISO standard for the display and sharing of Lightweight 3-D product information. The data format makes it possible to see and pass on 3-D product information in real-time over all phases of the product life cycle. JT improves collaboration as 3-D product data can be moved seamlessly between any number of CAD and PLM software products. By standardizing the format, companies have the opportunity to organize their 3D data exchange via JT. This is particularly interesting in multi-CAD applications.

What is JT

JT stores highly compressed facet inflections (triangles) as exchange format. The so-called tesselation is used. This decomposes polygons into small parts. In addition, attributes and CAD-specific nodes are stored. Dr. Wallner considers this topic in the training of large assemblies. The ISO IS14306 provides a detailed and comprehensive description of the JT data format, enabling companies and software vendors to use the format in their PLM workflow or software applications.

History

JT was developed in his first versions in 1998 by Hewlett Packard and Engineering Animation. Through 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 Siemens PLM Software.
