Learn how to convert IGS to 3DM with CAD Exchanger
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 3DM file is a native file format for 3D models in Rhinoceros CAD application software. It contains surface, point and curve information.
3DM files can be exported in both NURBS (non-uniform rational B-spline) and polygon mesh representations, making it possible for other CAD / CAM / CAE / graphic design software to edit those models.
In addition to Rhino CAD software, 3DM files can be opened with Autodesk Fusion 360.
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
