The JT Application Benchmark is a ProSTEP iViP Association and German Association of the Automotive Industry (VDA) project. Aim of the benchmark is to give a neutral overview of capabilities from currently available JT applications and improve interoperability between them.

This benchmark is composed of two independent building blocks: The “CAD-JT-CAD” benchmark where CAD to JT and JT to CAD translators were tested and the “JT with STEP AP242 BOM XML” benchmark, where JT applications with STEP AP242 XML capabilities were tested.

The focus of the CAD-JT-CAD benchmark was on the correct translation of geometry, tessellated data, PMI and metadata from CAD to JT and in a second step from JT back to CAD.

The JT with STEP AP242 XML benchmark focused on the capability of the translators to convert the product structure correctly into the STEP AP242 XML format. In a second step, the written STEP AP242 XML files should have been properly read by translators and target applications. Particularly the product structure and assembly attributes were checked.
