Convert CGR to 3DXML

Understanding CGR and 3DXML file formats

CGR (CATIA Graphical Representation) is a lightweight 3D visualization file format developed by Dassault Systèmes for use with CATIA and other Dassault applications. It is optimized for fast loading and viewing of complex 3D models, but does not contain full design data.

3DXML is another proprietary 3D file format from Dassault Systèmes, designed for sharing, visualizing, and collaborating on 3D data. 3DXML files can store geometry, textures, and product structure, making them suitable for a wide range of 3D applications within the Dassault ecosystem.

Why convert CGR to 3DXML?

Converting CGR to 3DXML is often necessary when you need to share 3D data with users who require more detailed model information or need to use the data in applications that support 3DXML but not CGR. 3DXML files are also more versatile for collaboration and downstream processes.

How to convert CGR to 3DXML

Direct conversion from CGR to 3DXML is not widely supported by generic file converters due to the proprietary nature of both formats. The best approach is to use Dassault Systèmes software such as CATIA or 3DEXPERIENCE platform, which natively support both formats.

Step-by-step conversion using CATIA

1. Open your CGR file in CATIA.
2. Go to File → Save As.
3. In the Save as type dropdown, select 3DXML.
4. Choose your destination folder and click Save.

This process preserves as much of the model data as possible, but keep in mind that CGR files are already lightweight and may not contain all original design features.

Recommended software for CGR to 3DXML conversion

• CATIA (by Dassault Systèmes) – Best for native support and highest fidelity conversion.
• 3DEXPERIENCE platform – For cloud-based workflows and collaboration.

There are no reliable third-party converters for this specific conversion due to the proprietary nature of both formats.

Tips and considerations

• Always verify the integrity of the converted 3DXML file by opening it in a compatible viewer.
• If you only have the CGR file and not the original CATPart or assembly, some data may be missing in the 3DXML output.
• For batch conversions, consider CATIA macros or automation tools within the Dassault ecosystem.
