Abstract

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

This benchmark is composed of two independent building blocks: The JT-Loop test where translators from JT to CAD and from CAD to JT were checked and the JT with STEP AP242 XML test.

The CAD formats for the JT-Loop test are CATIA V5 R19, Creo 2.0, NX 8.5 and SolidWorks 2012. The test models are converted with settings provided by the translator vendors. Focus of the benchmark is on the quality of the geometry, the translation of PMI and the translation of attributes.

Regarding geometry, it is checked whether the XT-BREP is correct transferred. It if checked if all geometric elements like curves, faces and points are present and correct.

Regarding PMI, type and content is benchmarked. Color, style, size, position and orientation of the annotations shall be kept.

In the JT with STEP AP242 XML test the focus is on the capability of the translators to write the product structure correct in the AP242 XML. In special, the assembly attributes are checked.
