JT Open Program

JT Open Program

The JT Open Program was formed by Siemens PLM software in 2003 at the request of a small group of forward-thinking corporations that saw value in the use of a common 3D format. That format is JT. The program now has over 100 members, including fortune 500 corporations located around the world and leading Academic institutions.

JT Open Program achievements include the publication of the JT file format specification and the creation of the industry leading no charge JT viewer, JT2Go. The publication of the JT specification was the impetus for ISO acceptance of JT as IS 14306. JT Open Program members continue to work collaboratively to expand the use of JT throughout the industry to achieve cost savings an efficiencies realized through the adoption of standard 3D JT data.

The JT Open Toolkit is a C++ application programming interface (API) that provides read/write access to all JT file format content including; product structure, meta data, attributes, LODs, PMI and precise XT B-Rep geometry. The JT Open Toolkit reads and writes ISO compliant JT files and all production versions of JT currently supported by Siemens PLM products. Included with the toolkit is the PLM XMK SDK and a PLM XML JT Adapter that reads and writes PLM XML schema compliant XML. In addition, the toolkit includes a Unity game engine plug-in for reading JT content dynamically into a unity session and the JT Utilities.
