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.
Navisworks is a native file of Navisworks® project review software by Autodesk.
Navisworks files come in three formats: NWD, NWF, and NWC. An NWD is a single file that contains all model geometry, environment, viewpoints, and review markups. An NWF file is a list of links to the original files. It doesn't keep model geometry and, to be opened, requires access to the original CAD files. An NWC is a cache file created from any native CAD or laser scan files, when opened in Navisworks.
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.
