File type: 3D Image
These files contain 2D/3D vector graphics data and are based on Initial Graphics Exchange Specificate or IGES.
This format is used by several CAD programs. These files are standard text files and are used for saving the vector data of graphics and also for exporting them.
These files can be used to store wire frame models, solid object representations or surfaces, circuit diagrams as well as other such complex objects.
In the year 1979 the IGES format was first introduced and has since then become a common standard which is used commonly for transferring, storing and exporting three-dimensional models data between CAD applications.
