Convert OBJ to 3DXML

Understanding OBJ and 3DXML file formats

OBJ is a widely used 3D geometry definition file format developed by Wavefront Technologies. It stores 3D model data such as vertices, texture coordinates, normals, and faces, and is supported by most 3D graphics applications. 3DXML is a proprietary 3D file format developed by Dassault Systèmes, primarily used for sharing and visualizing 3D data in applications like CATIA, ENOVIA, and 3DVIA.

Why convert OBJ to 3DXML?

Converting OBJ to 3DXML is essential when you need to use 3D models created in general-purpose modeling tools (like Blender or Maya) within Dassault Systèmes' software ecosystem. 3DXML supports advanced features such as product structure, metadata, and interactive visualization, making it suitable for engineering and industrial applications.

How to convert OBJ to 3DXML

Direct conversion from OBJ to 3DXML is not natively supported by most free 3D modeling tools. However, you can use specialized software or plugins to achieve this conversion.

Recommended software for OBJ to 3DXML conversion

• Dassault Systèmes 3DEXPERIENCE or CATIA: These platforms offer import tools and modules that can read OBJ files and export them as 3DXML. In CATIA, you can use File → Open to import the OBJ, then File → Save As and select 3DXML as the output format.
• 3DXML Player: While primarily a viewer, it can sometimes be used in conjunction with other Dassault tools for conversion.
• Spin 3D Mesh Converter: This third-party tool supports a range of 3D formats and may offer OBJ to 3DXML conversion, though results may vary.

Step-by-step conversion using CATIA

1. Open CATIA and go to File → Open.
2. Select your OBJ file and import it.
3. Once the model loads, go to File → Save As.
4. Choose 3DXML as the file type and save your file.

Tips and considerations

• Ensure your OBJ file is properly triangulated and free of errors before conversion.
• Some material and texture information may not transfer perfectly; check your 3DXML output for accuracy.
• For batch conversions or automation, consider scripting within CATIA or using Dassault Systèmes' APIs.

Conclusion

Converting OBJ to 3DXML is best accomplished using Dassault Systèmes' software, especially CATIA, for reliable results and full compatibility with the 3DXML format.
