IGS (Initial Graphics Exchange Specification) and IGES are synonymous terms referring to a standard file format designed for the exchange of 2D and 3D design data. Developed in the late 1970s, IGES is one of the oldest 3D CAD formats and was initially used in the aerospace industry for manufacturing parts. Today, it is employed across various sectors, including automotive and machinery.
Key Characteristics of IGS Files
- Stores surface information for a model
- Can also contain wireframes, circuit diagrams, engineering drawings, and solid models
- Utilizes ASCII text format
- Primarily saved with the .igs file extension

FAQ
What is an IGS/IGES file?
IGS (Initial Graphics Exchange Specification) and IGES are synonymous terms referring to a standard file format used to exchange 2D and 3D design data. It was developed in the late 1970s and is primarily used in the manufacturing industry, particularly in aerospace, automotive, and machinery sectors. IGS files can contain surface information, wireframes, circuit diagrams, engineering drawings, and solid models. They are typically saved with the .igs file extension.
What software can I use to view IGS files in Windows?
Since Windows does not natively support IGS files, third-party applications are required for viewing them. Some popular options include IGS Viewer, FreeCAD, Gmsh, Autodesk Viewer, 3DViewerOnline.com, gCAD3D, and 3dusher.com. These tools offer varying features, from basic viewing and navigation to advanced editing and conversion capabilities.
How can I convert IGS files to other formats?
Several software applications allow you to convert IGS files to other 3D file formats. FreeCAD, Gmsh, and gCAD3D are notable examples that support conversion to formats like STP, STL, OBJ, DXF, and VRML. Additionally, online services such as CloudConvert and Zamzar provide conversion capabilities for IGS files.
What are the advantages of using IGS files?
IGS files offer several advantages, including:
- Standardization: IGES is a widely recognized and accepted standard format, ensuring compatibility with various CAD software and manufacturing systems.
