JT (Jupiter Tessellation) is an openly-published ISO-standardized 3D CAD data exchange format used for product visualization, collaboration, digital mockups, and other purposes.[1] It was developed by Siemens.[1]

It can contain any combination of approximate (faceted) data, boundary representation surfaces (NURBS), Product and Manufacturing Information (PMI), and Metadata (textual attributes) either exported from the native CAD system or inserted by a product data management (PDM) system.

The JT format contains a scene graph representation of an assembly, nested sub-assemblies of parts with CAD specific node and attributes data.[2]: 17  Facet information (triangles) is stored by using geometry compression techniques. Visual attributes of 3D scene and model like lights, textures, and/or materials are supported. Product and Manufacturing Information (PMI), Precise Part definitions (BRep), additional metadata, and a variety of representation configurations are supported. The JT format is designed to be streamable.[2]: 17
