3DS is one of the file format used by the Autodesk 3D modeling, animation and rendering software. It once was native for the old Autodesk 3D Studio DOS and eventually has grown to become a de facto industry standard for transferring models between 3D programs, or for storing models for 3D resource catalogs.
3DS is aimed at providing an import/export format, retaining only essential geometry, texture and lighting data.
IGES (Initial Graphics Exchange Specification) was among first vendor-neutral CAD formats designed to enable interoperability between different CAD systems. The latest versions of IGES have been approved by ANSI (American National Standards Institute) and published by US PRO (U.S. Product Data Association). The latest officially approved version of the IGES standard is version 5.3 which was published in 1996. Nonetheless, IGES remains a broadly used format (along with STEP) supported by all major CAD/CAM/CAE systems such as CATIA, Autodesk Inventor, Solidworks, Solid Edge, NX, Pro/Engineer, Creo and multiple others. IGES files usually have *.igs or *.iges file name extensions.
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
