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.
ASM (Solid Edge Assembly) is one of the data file types used by Solid Edge CAD software. The files with .asm extension contain 3D parts (.prt) which consist of assemblies. ASM by itself, does not contain geometric information – it stores only the rules for connecting parts.
ASM (Solid Edge Assembly) also has no connection with assembly language, though this also uses an .asm extension.
Among CAD applications that support ASM extension are PTC Creo and Autodesk Fusion 360.
A CAD file is an output of a CAD software, containing key information about the designed object: its geometry and topology representation, 3D model hierarchy, metadata, and visual attributes depending on the format of the file.
