JT Open Technology

JT Technology in Use

JT is a mature lightweight data format that already enjoys widespread use in the automobile and aerospace industries and is equally suitable for all manufacturing industry applications. The success of JT and applications that exploit it is such that JT has become the preferred common data format for many large end-users. The JT data representation is:

  • A rich data model with robust entity support
  • A high-performance, compact persistence archive format for graphics data
  • The best-in-class for supporting large assembly ⁄ model interactive capabilities
  • CAD-neutral supporting all major MCAD applications

Software product development organizations have developed translators from the popular MCAD systems into JT. It is nearly always the only format common to the major applications that might be used in an enterprise.

JT data can be very lightweight, holding little more than facet data or it can be richer and hold associations to the original CAD information, assemblies, product structure, geometry, attributes, meta data and PMI. It supports multiple tessellations and level-of-detail generation.


JT data is well suited to visualization applications. The JT Open Toolkit provides API access to the JT information in a manner that allows the visualization application to configure or render the data most consistently with their paradigm


The JT Open Toolkit and JT data are well suited to support collaboration applications. Most collaboration capability revolves around product structure integration, design-in-context or design reviews – all of which are supported by the JT data representation and toolkit access

Data Sharing

The JT Open Toolkit and JT data are well suited to providing an enhanced capability within a multi-CAD design paradigm. Lightweight representations can be used for design-in-context, with the ability to delve into the precise representations if actual model information is needed for design operations.
