Positioning of JT in V-Model


Reasons for promoting standardization:

  • Enable lightweight 3D Visualization (Scope: ISO) and exact geometric representation (e.g. for measuring) Secure CAD Interoperability and provide efficiency for
    • internal communication (downstream processes, multi-CAD Design in Context) across business units / cross-lifecycle, cross-discipline (Scope: Industrial Application Package)
    • external communication: OEM/OEM; OEM/Joint Venture; Customer/Supplier; Customer/Service Provider)
  • Achieve consistency across company borders
  • Safeguard long-term data retention and long-term usage of standard (Scope: Industrial Application Package)


Relevance and Benefit for MBSE

  • For the In-house processes of many/most companies JT is already the 3D backbone, and just one piece in the MBSE puzzle - but an important one. As a LTA-able IT Standard, and with its metadata options, JT is the ideal complement among the proposed MBSE IT Standards. More so in the context of Collaborative Systems Engineering, where (challenging) interfaces/gaps have to be bridged.

Risks and Impediments

Although the distribution of the JT usage is very high, the usage in (bidirectional) data exchange processes is very meagre. This is an impediment on the track to excellence. To put it positively (as a chance!): A comprehensive usage of JT as the leading 3D data exchange format would bring the format its format quality aspects to a new level.
