JT2Go is the industry leader for viewing 3D JT data on mobile and desktop devices. Siemens PLM provides JT2Go free of charge. JT data can be generated from nearly all the major CAD/CAM/CAE tools available in industry today. Using lightweight JT models detailed descriptions of 3D content can be shared throughout your enterprise.

JT files can contain geometric definitions of individual 3D Models and Assemblies as well as dimensions, model properties and arrangements of Product Manufacturing Information (PMI) know as Model Views. With JT2Go users can navigate product structure trees, view predefined model views and interrogate model properties

JT was defined by Siemens PLM and is supported through the JT Open Program. The JT file format specification was adopted by ISO as an international standard in 2012 and is available from ISO as IS 14306:2012. The JT file format specification is published free of charge by Siemens PLM and is available from

Note: JT2Go for iOS will attempt to load any size JT file. For best performance we recommend loading JT data no larger than ~30 Mgb.

Customer Reviews

Half-baked like most Siemens offerings


No clue how to open a file. Tapping the load button takes user to some inbox. How do I get files to this inbox? Instructions on website are worthless.

Can not open JT files after Update


After the latest update I lost the ability to open up JT files from other apps such as Box, and Google Drive. This functionality needs to be added back asap otherwise this app is not very usable. This is extremely frustrating since this app worked great before



Very easy to use.
