.igs file type #1: IGES 3D format

Any igs file you encountered is almost certainly 3D object or model saved in the IGES (Initial Graphics Exchange Specification) format.

Further details:

IGS or IGES files (Initial Graphics Exchange Specification) file represent a standard file format used for exchanging 3D data between different CAD (Computer-Aided Design) programs.

It was first published in 1980 by the U.S. National Bureau of Standards and was the first widely accepted CAD file format. The IGES format serves as a neutral data format to transfer the design to a dissimilar system.

It allows a 3D model file to be shared among various CAD systems. It can store wireframe models, surface or solid object representations, circuit diagrams, and other objects.

The IGS format has been superseded by STEP format, which has a wider range of features, but is still widely used due to its broad compatibility with a range of 3D modeling applications.

What is the meaning of a file extension?

File extensions are characters that appear after the dot in a computer file's name. For example, the file "unknown-file.igs" has the file extension "igs". This is used to identify which program should open the file or what file type it is.
File extensions help you organize and manage files. They provide a quick and easy way to identify and associate the file type with the appropriate software.
