USD & USDZ File Format - Universal Scene Description by Pixar
Universal Scene Description (USD), developed by Pixar, is a powerful framework for creating, editing, and exchanging complex 3D scenes. Now widely adopted in the VFX, animation, and AR industries, the USD ecosystem supports large-scale pipelines through its modular, scalable, and cross-platform architecture. USDZ is its optimized variant for mobile AR applications, especially on Apple devices.
Key Features of USD and USDZ
- Modular and Composable Architecture: USD enables efficient scene composition by referencing multiple files, allowing teams to collaborate on complex projects without data duplication or conflicts.
- Cross-Platform Interoperability: USD ensures accurate data exchange across software platforms like Maya, Blender, Unreal Engine, and more - ideal for collaborative, multi-tool workflows.
- Hierarchical and Layered Scene Representation: Easily organize 3D data using namespaces, variants, layers, and references, providing unparalleled control over versioning and detail management.
Convert USD, USDA, USDC, and USDZ Files
Our Autoconverter and Automesher Application software supports full-featured conversion for USD, USDA, USDC, and USDZ formats. Powered by the OpenUSD framework, our tools allow you to import, export, and convert USD files to popular 3D formats like GLTF, FBX, STL, OBJ, SKP, and STEP. Whether you are developing for AR, animation, or CAD pipelines, our converters offer precision and compatibility across platforms.

IGES File Format - Initial Graphics Exchange Explained
The IGES (Initial Graphics Exchange Specification) file format is widely used across CAD (Computer-Aided Design), CAM (Computer-Aided Manufacturing), and CAE (Computer-Aided Engineering) industries for transferring 3D models and complex designs between different software platforms. Developed in the 1980s and standardized by ANSI and ISO, IGES remains a crucial, legacy-neutral format for 3D data exchange, ensuring long-term interoperability.
What is an IGES (.IGS) File?
IGES files store detailed 3D CAD data using a text-based format that can represent wireframes, surfaces, and solid models. It enables seamless sharing of geometric information without dependency on proprietary software, making it ideal for collaborative projects across engineering, manufacturing, and design fields.
Key Features of the IGES/IGS Format
- Text-Based Geometry Storage: All geometric and structural data is saved in human-readable ASCII text, allowing easy manual editing but often resulting in larger file sizes for complex designs.
- Color Information: IGES supports color at the assembly level, preserving important visual distinctions between different components and parts in a model.
- Transparency Limitations: Unlike newer 3D file formats, IGES does not support transparency (alpha channels), meaning that opacity settings in original designs are not retained after export.
IGES/IGS File Conversion and Processing
Autoconverter offers complete read and write support for IGES files using the Open Cascade technology stack, ensuring full compatibility with the latest IGES specifications. It processes IGES data as triangulated mesh geometry for maximum compatibility. For workflows requiring preservation of native NURBS surfaces and smooth 3D definitions, we recommend using Autoshaper, which maintains original surface accuracy throughout the conversion process.
