STP STEP File Format (Standard for the Exchange of Product Model Data)

The STEP file format (also known as STP) is a widely recognized ISO standard for exchanging 3D data across different computer-aided design (CAD), computer-aided manufacturing (CAM), and computer-aided engineering (CAE) systems. Designed for seamless interoperability, STEP files enable accurate, reliable sharing of complex 3D models across industries like engineering, aerospace, and manufacturing.

Key Features and Benefits of STEP Files

  • Universal Interoperability: As an ISO-standardized format, STEP files eliminate vendor lock-in, supporting smooth 3D data exchange between major CAD software such as SolidWorks, NX, Creo, CATIA, AutoCAD, and more.
  • Broad Software Compatibility: Widely accepted across industries, STEP (.stp, .step) files ensure consistent workflows and simplify collaboration between different design teams and software platforms.
  • High Precision and Integrity: Unlike mesh-based formats like SKP, OBJ, or STL, STEP files maintain the exact geometry, dimensions, and topological details of 3D models without introducing mesh distortions or inaccuracies.
  • Assembly Color Support: STEP files retain color information at the assembly level, enhancing design visualization. However, they do not support transparency effects (alpha channel), so transparent objects are rendered opaque.

How to Convert and Optimize STEP Files

Large STEP files can be a challenge, especially when dealing with complex or highly detailed models. Our Autoconverter software provides an efficient solution, allowing you to optimize and convert STEP files easily. By using the faceted BREP (Boundary Representation) method, Autoconverter can significantly reduce file sizes - sometimes by up to 30% - without losing critical model fidelity.

Powered by the industry-leading Open Cascade technology stack, Autoconverter ensures full compatibility with the latest STEP standards and offers fast, high-quality STEP to STL, OBJ, SKP, or other 3D file format conversions.

USD 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.
