.IGS File Extension
File Type 1IGES Drawing File
What is a IGS file?
2D/3D vector graphics format based on the Initial Graphics Exchange Specification (IGES); used by many CAD programs as a standard ASCII text-based format for saving and exporting vector data; can store wireframe models, surface or solid object representations, circuit diagrams, and other objects.
The IGES format was introduced in 1979 and became the standard for transferring three-dimensional models between CAD programs. In recent years, however, it has been replaced by the newer .STP format.

.IGS File Association 2
3D scene used by Indigo Renderer, an application used for generating photorealistic images; often saved as an export from another 3D modeling package that has the Indigo Renderer plug-in, including Blender, 3ds Max, Cinema 4D, Maya, SketchUp, or Revit.
Once a 3D scene has been imported into Indigo Renderer, it can be rendered into a final image. The software supports GPU acceleration so that images can be generated more quickly.
