Conversion from GLB to CATIA V6 (3D XML) is not supported yet :(

GLB is a standardized file format for sharing 3D data used in virtual reality, augmented reality, games, and online applications. GLB files are a binary form of the GL Transmission Format (glTF) file, which employs JSON (JavaScript Object Notation) encoding.

Supporting data such as 3D scenes, models, lighting, materials, and geometry / animation are all stored in a single GLB file, eliminating the need for extra support files to access textures, geometry, shaders, animation, and other types of data required for a 3D view. GLB files are 30% smaller than glTF and its associated files, so they load and process faster.

GLB is compatible with various 3D visualization programs, such as Microsoft Paint 3D, Microsoft Remix 3D, Blender, Trimble 3D Warehouse, SketchUp.

3DXML is an open-standard proprietary 3D file format developed and supported by Dassault Systemes. 3DXML files are typically created as exports from Dassault Systemes' 3DEXPERIENCE application. The 3DXML file is a zip archive file consisting of a BOM file and one or more 3D representations stored in either XML or binary format. Compact file size allows users to transfer 3D XML quickly and embed it into websites, emails, and various MS Office documents. Therefore, the format is commonly used to integrate 3D data into technical documentation.
