Product Information

Working within the Dassault Systemes Composer architecture CATIA Composer provides interactive, batch and command line interfaces for CATIA Composer users to directly access JT data independently of any JT products. It is self-contained and version independent for improved ease of use. CATIA Composer users can open JT data including geometry, assemblies, product structure, metadata and Product Manufacturing Information (PMI).

How it works

It enables users to interactively open JT data directly in the CATIA Composer environment. Once data has been opened it can be manipulated using the extensive functionality of the CATIA Composer application, allowing the user to access any product structure information, and geometry, while authoring CATIA Composer output. In addition to assembly structure and geometry information any JT Product Manufacturing Information (PMI) data is also converted, enabling it to be used for manufacturing output purposes. JT PMI (Product Manufacturing Information) is created as equivalent CATIA Composer data structures.


JT assembly and tessellated or BREP geometry is translated into native CATIA Composer assembly structure and geometry definitions. In addition to the already supported native JT and PLMXML assembly structure definitions, the translator now supports the ability to read an assembly structure defined in STEP AP203 BOM format with subordinate JT files.

| Available Options

As well as the interactive solution there are also two optional licenses available to automate the creation of CATIA Composer output using the CATIA Sync or the CATIA Enterprise Sync interface.

The CATIA Sync interface enables the creation of CATIA Composer .smg output using the batch mode translator.

The use of the CATIA Enterprise Sync command line interface allows the conversion process to be integrated into any process oriented operation e.g. the creation of CATIA Composer .smg representations of the JT data as an automated process within a 3D Experience Product Lifecycle Management workflow.

Re-use 3D design data for document publishing

This plug-in product enables the re-use of 3D design data for document publishing processes. It enables CATIA Composer users across the enterprise to work with JT files. By directly using JT data it lowers costs, improves quality and reduces timescales for document creation.

Parallel Development

Theorem’s strategic partnerships with Dassault Systemes and Siemens, ensures that there is a parallel development between the latest releases of CATIA Composer, JT and Theorem’s products, allowing Theorem to continue to provide solutions to the Composer community, supported by the vendors, ensuring high quality support.
