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.
3D Model Formats – Useful for Drafters
3D modeling is widely known everywhere and used in countless mediums, ranging from architectural, illustrations, video games, engineering, and advertising. This technical term is also used on the web, where rendering contains 3D modeling along with web development. There are several 3D file formats available for 3D models, including separate options merely used in specialized labs and well-known formats available in most digital devices. Let’s take a brief overview of the following 3D file formats that are relevant to designing and rendering 3D models:
