OBJ vs FBX vs glTF – Complete 3D Model Format Comparison Guide
Last Updated: 17 July, 2026
OBJ vs FBX vs glTF: Which 3D Model Format Should You Use? Three-dimensional models are now an essential part of modern CAD, engineering, manufacturing, architecture, product visualization, simulation, digital twins, and web-based applications. As 3D workflows have evolved, several file formats have emerged to store, exchange, render, and distribute 3D models across different software and platforms.
Today, developers, engineers, designers, and technical teams commonly encounter three widely used 3D model formats: OBJ, FBX, and glTF.
Future of CAD File Formats: What Everyday Users Should Know in 2025
Last Updated: 22 Sep, 2025
The digital blueprints of our world are on the cusp of a revolution. Computer-Aided Design (CAD) has long been considered the backbone of engineering, architecture, manufacturing, and product design. Traditionally, CAD file formats like DWG, DXF, STEP, STL, and IGES were mainly tools for engineers and industry professionals. However, in 2025, the role of CAD file formats has shifted dramatically—affecting not only businesses but also everyday users who interact with 3D models through printing, virtual reality, online collaboration, and even e-commerce.
