What is a JT file?
A JT file (.jt) is an open 3D visualization format widely used to share product and assembly data in engineering and manufacturing workflows. Its structure and data rules are defined by ISO 14306, the international standard for the JT format, which covers product structure, tessellated geometry, and related visualization content.
What is the relationship between JT files and Siemens?
The JT format was originally developed by Siemens for lightweight 3D visualization and collaboration. It is now maintained as an open format under ISO 14306 and is widely used with Siemens products such as NX and Teamcenter, as well as by other CAD and PLM tools that publish JT visualization data. JT File Viewer is an independent viewer and is not affiliated with Siemens.
