IGS File Extension

What is IGS file?

IGS file is a graphics file encoded in IGES format, and is used in CAD software environment to store 2D/3D vector image data. The file can contain various data for the project, such as wireframe models, surface or solid objects representations, circuit designs, etc. IGS file is saved in ASCII text format.

Short history of IGS file format

IGS project file closely follows Initial Graphics Exchange Specification (IGES) file format specification, first published in 1980. It quickly became the standard format for storing and exchanging 3D model data used in CAD software environment. This solution greatly facilitates distribution of projects among users working that use different types of CAD software. In recent years however, it has been replaced by newer STP format, which is used to this day. IGES standard specification document was last updated in 1996.
