An IGS extension (Initial Graphics Exchange) is a 2D or 3D CAD vector file that can store wireframes, surfaces, solids, etc. IGS is mainly used for exchanging CAD drawings based on the Initial IGES (Graphics Exchange Specification) format.
The IGS file structure is based on the ASCII text-based format, which is used in numerous CAD software applications for delivering high-end graphics.
Among CAD applications that support IGS extension are Autodesk 3ds Max, Autodesk Fusion 360, Dassault Systemes CATIA, and Autodesk Inventor.
A DWG file is a database of 2D or 3D drawings created with AutoCAD. It contains vector image data and metadata describing the contents of the file. DWG files are related to .DXF files, which are ASCII versions of DWG files.
A CAD file is an output of a CAD software, containing key information about the designed object: its geometry and topology representation, 3D model hierarchy, metadata, and visual attributes depending on the format of the file.Read more
