📁 Convert IGES to SAT: IGS Model to ACIS Text File Converter

How to Convert IGES to SAT?

Converting IGES to SAT has never been easier. Follow our step-by-step guide and let our reliable tool do the heavy lifting:

  1. 📥 Download and Install

    Download and install Autoconverter on your system. This application will let you to convert your IGES files to SAT format - no additional CAD software required.

  2. 📂 Open Your IGES File

    Go to File > Open… to load your IGES file (*.igs, *.iges), or drag and drop it directly into the application window. The model loads into the 3D viewport for inspection before converting.

  3. 💾 Save As SAT Format

    Go to File > Save As…, select SAT (*.sat) as the output format, choose your destination folder and filename, then click Save to complete the IGES to SAT conversion.

IGS 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.

SAT SAT File - Standard ACIS Text Format (.sat)

SAT files are ASCII-based 3D modeling files created using the ACIS geometric modeling kernel, developed by Spatial. Widely used in CAD applications, SAT (Standard ACIS Text) files store exact geometry and parametric data for solid modeling. This format enables accurate data exchange between leading CAD software such as AutoCAD, SolidWorks, Fusion 360, and Revit.

Key Features of SAT Files

  • High-Precision Geometry: Encodes accurate B-Rep (Boundary Representation) data using NURBS surfaces and curves.
  • CAD Interoperability: Supports seamless cross-platform exchange between AutoCAD, SolidWorks, Rhino, Revit, and other CAD tools.
  • Feature-Rich Modeling: Retains advanced design elements like fillets, lofts, extrusions, blends, and Boolean operations.
  • Readable Format: Human-readable ASCII text file that simplifies debugging and version control in collaborative workflows.
