Why use the CATIA V5 to NX Translator

Theorem’s CATIA V5 <> NX CADverter is a high quality, cost effective translation solution designed to help solve the issue of working with and sharing incompatible data formats. This product is designed for companies using CATIA V5 and NX who need an effective method of collaboration between the two mechanical CAD systems.

The CATIA V5 <> NX CADverter supports collaboration between companies, their customers and suppliers enabling native 3D mechanical design data to be re-used in downstream activities helping to reduce overall project costs. Working with native design data helps to simplify the entire process, improves communication and provides access to all of the necessary information required to progress a product design to manufacture and then eventually to market.

Using the CATIA V5 to NX translator

The CATIA V5 to NX translator is a direct database converter between CATIA V5 and NX. It enables the user to convert all forms of 3D mechanical design geometry, as well as assembly and attribute information, between these two systems.

The translator can be purchased as a uni-directional, CATIA V5 to NX, or NX to CATIA V5 product, or as a bi-directional product. It can be used interactively or in a batch mode, from a standard CADverter Unified Interface.

  • An interactive version of CADverter can be run from within the menu system of either CATIA V5 or NX
  • The translator converts all 3D wireframe, surface and solid geometry.
  • If assembly data (product structure) is in the file, the assembly structure will be mapped between the two systems as well as colour information.
  • The user can filter data to optimize the process.
  • Can be integrated with any workflow or PDM/PLM environment
  • Support 3D Product Manufacturing Information from CATIA V5 into NX
  • If you wish to visualize and interrogate the CATIA V5 or NX data this can be done by using the integrated viewer product, which is a feature of the user interface.
  • There is now a low-cost 3D PDF addon available for this CADverter product allowing an interactive 3D PDF document to be output. Users will have the extra benefit of a 3D publishing feature which enables the output CAD data to be published as a 3D PDF alongside the original translated format.
  • An additional annual support contract is available ensuring limited product down time and ongoing compatibility with all source applications.

Which version is right for you?

There are three versions of the CATIA V5 to NX translator available which have their own specific benefits:


CAA - Translator

This product requires access to an installed license of the CATIA V5 application to run Theorem’s high quality and cost effective CATIA V5 to NX translator. The CAA version  enables the direct translation of CATIA V5 data to and from the NX format. It enables the translation of the assembly structure, geometry, attributes and, where available, 3D Product Manufacturing Information (PMI) and Metadata between CATIA V5 and NX, with access to a license of CATIA V5 and NX to run.

Independent Version

Licenses of vendor-specific CAD applications can be expensive resources to purchase and also to maintain, so it doesn’t help when they are tied up for long periods of time or when there aren’t enough available licenses to be able to multi-task different design projects effectively.

Working independently of CATIA V5, users can create and consume NX data using the CADverter without needing access to a license of the CATIA V5 application.

Theorem’s CATIA V5 Independent solution helps support collaboration between companies, their customers and suppliers, enabling original 3D mechanical design data to be re-used in downstream activities helping to increase data quality and reduce overall project costs; without needing access to a license of the CATIA V5 application.

Multi-CAD enables CATIA V5 users to work interactively with NX data inside of a design session without the need for external translation. 

Theorem’s Multi-CAD application is an interactive, low cost and efficient solution to the problems that can be encountered when a CATIA V5 user needs to work on projects where NX data needs to be regularly worked on during a design project.

Multi-CAD maintains the integrity and correct version of the imported data as it comes into CATIA V5 by keeping an associative link back to the source data so that “design in context” can be undertaken without the need for external translation of non CATIA V5 parts and assemblies.

With Multi-CAD, CATIA V5 users are able to use standard CATIA commands to select a part or assembly designed in NX, and insert it as a node on their CATIA V5 design tree; either as a single component or full assembly.
