Convert IGES to 3DXML

Understanding IGES and 3DXML file formats

IGES (Initial Graphics Exchange Specification) is a widely used CAD file format for exchanging 2D and 3D design data between different CAD systems. It stores geometry, annotations, and other design information in a text-based format, making it highly interoperable.

3DXML is a proprietary 3D file format developed by Dassault Systèmes. It is used for sharing, visualizing, and collaborating on 3D models, especially within the Dassault Systèmes ecosystem (such as CATIA, ENOVIA, and 3DVIA). 3DXML files are based on XML and can contain geometry, textures, and metadata.

Why convert IGES to 3DXML?

Converting IGES to 3DXML is often necessary when you need to use CAD data from a neutral format (IGES) in Dassault Systèmes applications or share 3D models with users who rely on the 3DXML format for visualization and collaboration.

How to convert IGES to 3DXML

Direct conversion from IGES to 3DXML is not natively supported by most CAD software. However, you can use specialized software or a two-step process involving intermediate formats. Here are the recommended methods:

1. Using Dassault Systèmes CATIA

CATIA is the best software for this conversion, as it supports both IGES import and 3DXML export. Follow these steps:

1. Open CATIA.
2. Go to File → Open and select your IGES (.igs or .iges) file.
3. Once the model is loaded, go to File → Save As or File → Export.
4. Choose 3DXML as the output format and save the file.

Note: You need a licensed version of CATIA with the appropriate modules enabled.

2. Using 3DEXPERIENCE platform

The 3DEXPERIENCE platform by Dassault Systèmes also supports IGES import and 3DXML export. The process is similar to CATIA:

1. Upload your IGES file to the platform.
2. Open it in the 3D modeling app.
3. Export or save as 3DXML.

3. Using intermediate formats

If you do not have access to CATIA or 3DEXPERIENCE, you can use a two-step process:

1. Convert IGES to a format supported by free or more accessible software (e.g., STEP, STL).
2. Import the intermediate file into a program that can export to 3DXML (such as CATIA).

Recommended software for IGES to 3DXML conversion

• CATIA (by Dassault Systèmes) – Best for direct conversion.
• 3DEXPERIENCE platform – Cloud-based solution for IGES and 3DXML workflows.
• Autodesk Inventor or SolidWorks – For intermediate conversions, but final 3DXML export still requires Dassault Systèmes software.

Summary

To convert IGES to 3DXML, the most reliable method is using CATIA or the 3DEXPERIENCE platform. These tools ensure accurate geometry and metadata transfer, making them ideal for professional workflows.
