JT File Format

Open CAD file

JT (Open CAD file) is a 3D model format developed by Siemens PLM Software that was designed as an open, high-performance, compact, persistent storage format for product data. JT files are used for product visualization, collaboration and data sharing. 

JT files may contain approximate (faceted) data, exact boundary representation surfaces (NURBS), product and manufacturing information (PMI) and metadata. JT files can be exported by native CAD systems and imported by product data management (PDM) systems. Although the JT format is primarily used in the automobile and aerospace industries, it can be used for any similar manufacturing industry application.

Programs that open JT files include: Siemens PLM NX, Siemens PLM I-DEAS, Siemens PLM Solid Edge, Dassault Systemes CATIA, PTC Pro/ENGINEER, Autodesk Inventor

There is a well reviewed JT Viewer for Windows 8 (non-desktop). I want to upgrade existing visualization tools to work with W8.
TransMagic can also serve as a JT viewer, able to open, measure, dimension, interrogate JT files as well as read and manage PMI, and save out the file to all major CAD and polygonal formats.
CATIA, or at least the $22,000 package I have, does not open .jt files. Thanks Dassault.
