What is JT?

JT is the World’s Most Widely Used 3D File Format for PLM

JT is the common language of PLM and is the world’s most widely used 3D format. JT is the first ISO International Standard ( IS 14306-1) for 3D visualization and collaboration. Compact and accurate, JT is used throughout the product development lifecycle in all major industries to communicate the critical design information typically locked up inside a CAD file.

Siemens PLM Software customers rely on JT to be the most robust 3D visualization format available.
