Some of the highlights of the JT format include:
- Product Structure (BOM) with full Instance support with Absolute Occurrence identification
- Built-in support for assemblies, sub-assemblies and part constructs
- Flexible single or multiple partitioned structure
- Built-in streaming support
- BREP, including integrated support for industry standard Parasolid/XT format
- Product Manufacturing Information in support of paperless manufacturing initiatives
- Precise and imprecise wireframe
- Discrete purpose-built Levels of Detail
- Extensible data paging architecture
- CAE results visualization
- Wire harness information
- Triangle sets, Polygon sets, Point sets, Line sets and Implicit Primitive sets (cylinder, cone, sphere, etc…)
- Full array of visual attributes: Materials, Textures, Lights, Shaders
- Hierarchical Bounding Box and Bounding Spheres
- Support for viewing optimizations such as view frustum and occlusion culling and fixed-framerate display modes
- Layers, Layer Filters

Additional Information
JT Format was designed to be easily integrated into enterprise translation solutions producing a single set of 3D digital assets that seamlessly and simultaneously supports a full range of downstream processes from lightweight web-based viewing to full vehicle digital mockups.
- Concentrates on being a flexible, complete representation of a 3D Digital Asset (typically originating from a CAD system Part file) in virtual product development processes. It does not (by itself) define the complete viewing environment in which the asset will be visualized. This intentional separation of content from presentation is an important enabler for this.
- Because of the emphasis on JT as a basis for creating a persistent visualization database, the JT file must retain a high degree of correlation and granularity alignment with original data (i.e. CAD) and data management systems (i.e. PDM). This is done to permit automatic, incremental re-translation of CAD components as they change to keep the visualization database up-to-date. This characteristic has been put to the test in many production environments.
- JT file format is closely aligned with run-time representation for fast and efficient loading/unloading, but does not define interaction behavior within the file format, either in the form of specific viewer controls, viewport information, animation behavior or other event-based interactivity. This makes the files more easily reusable in configuration management systems and dissimilar application interoperation.
- The multiple LOD strategy of JT uses discrete individual geometry nodes in the scenegraph. One of the benefits of this mechanism is that it permits Level of Detail representations to be created with processes other than decimation (i.e. progressive meshes). For example, feature removal, visibility shells, alternative tessellation parameters, hand-tuning are all methods that can be used to create purpose-specific LODs.
- JT is an established format with a proven track record in the area of Visualization Database (virtual mockup) representation. It is also an established format that enables large scale digital mockup and high-performance visualization.
- While the JT file format itself is extensible, in practice the content is carefully evolved to guarantee the highest degree of compatibility between JT data sources (i.e. translators) and JT data consumers (e.g. viewers). This guarded evolution rather than open-source style evolution reduces the format mutation problems that have plagued other open standards such as VRML and STEP.
- JT format is supported by a company whose full time business is supplying visualization technology, it is in production use on thousands of engineering programs, across hundreds of thousands of seats against terabytes of production data.
- Adoption and Coverage: JT Data can be created from every major 3D product design application (i.e. CAD system) available. Significant investment has been put into this broad coverage over the years. While other 3D initiatives may pursue formal standardization processes, the true measure of a standard is the degree to which it is adopted within the industry it serves.
- Industry focused: The JT format has significant presence in Automotive, Aerospace and Heavy Equipment industries.
