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.
An IAM file is an assembly model created with Inventor CAD and engineering software by Autodesk.
The IAM format comprises parts and subassemblies linked through assembly relationships. A subassembly in an IAM file is a self-contained unit with its collection of parts.
The .iam extension of an Autodesk Inventor Assembly Data File can be viewed using the following software: Autodesk Inventor / Inventor View, and Spaceclaim Engineer software. Autodesk Viewer web application and Fusion 360 integrated CAD / CAM / CAE software environment can import and render an assembly model created with Inventor.
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.Read more
