CATIA V5 to NX Translator

CATIA V5 to NX Translator

Read and Write Data Between these Two Formats

Why Use the CATIA V5 to NX Translator

Theorem’s CATIA V5 <> NX translator 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 translator 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.

What You Need to Know About 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 Theorem Unified Interface.


The CATIA V5 to NX Translator Can Be Used in a Variety of Ways:

  • An interactive version of the translator 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 CADTranslate (previously called 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?

For companies needing to translate CATIA V5 data Theorem provide two technology solutions, both use Dassault Systemes API tools which are supported by Dassault, they are the CAA and Interop APIs. Being supported by Dassault means data compatibility is assured, along with back up support from the vendor.


Our CATIA V5 products which use Dassault’s CAA libraries link to and require access to a V5 license in order to run. As such that enables them to be run directly inside V5 with an interactive “save as” capability, as well as being able to run in batch mode and linked to PLM.


Our CATIA V5 products which use Dassault’s Interop libraries do not need a separate V5 license to run, as such they provide an independent self-contained solution for companies who do not have a CATIA V5 system installed or access to a license. They can be run interactively using the Theorem GUI or in batch mode and linked to PLM.

Gain Competitive Advantage

Theorem’s CATIA V5 to NX Translator

  • Facilitates the re-use and sharing of 3D design data
