How to convert IGES (.igs) to 3ds Max (.max)?

PolyTrans|CAD+DCC performs mathematically precise CAD, DCC/Animation, GIS and BIM 3D file conversions into all key downstream 3D packages and file formats. Okino software is used and trusted throughout the world by many tens of thousands of 3D professionals in mission & production critical environments, backed by respectable personal support directly from our core development team.

IGES

IGES was the defacto 'go-to' MCAD translation file format but has long since been overtaken by the STEP file format. IGES and STEP are equally good file formats to translate CAD and MCAD model data files but it all depends on how well the files are exported from the corresponding MCAD modeller software.

As an ANSI standard since 1980, IGES has been used in the automotive, aerospace, and shipbuilding industries. Version 5.3 (1996) is the last published and stable standard of IGES. IGES is one of the original CAD vendor-neutral 3D data translation file formats which was designed for high fidelity data exchange between all major professional 3D modelling applications. IGES uses the .igs and .iges file extensions.

Okino's PolyTrans|CAD provides for a defacto 3D IGES file conversion solution used by the world's primary & professional engineering, aerospace, military, corporate, animation/multi-media and VR/AR industries.

A much deeper overview plus explanation of IGES, and how it can be best used + understood, is outlined in this Okino WEB page. It is vitally important to understand the differences between "old school" and "new school" IGES files, as this is little understood by most 3D graphics users.

3ds Max

3ds Max has been the flagship DCC/Animation system of Autodesk since its introduction in 1996. It replaced 3D Studio R1-R4 which was a DOS based variation. Both were developed by the Yost Group and licensed to Autodesk.

As is very little understood, no program on this planet can read or write 3ds Max ".max" files because the full geometry modifier stack of the 3ds Max software, and its various plugin modules, are needed in order to properly evaluate the file before it can be rendered. This is what forced Okino to write its PolyTrans-for-3dsMax system, which allows for all Okino 3D converters to run within 3ds Max itself. For example, if you want to convert to/from CINEMA 4D (.c4d files) then you would do so entirely inside of 3ds Max.

Okino has a very long history with 3ds Max as it got on board in 1986 when Tom Hudson (of the Yost Group) first released "CAD-3D" on the Atari|ST computer. That program morphed into 3D Studio on DOS (.3ds file format) and then into 3ds Max (.max file format).

Note: Please do not confuse the 3D Studio's .3ds format with the 3ds Max .max format. You will find throughout the 3D industry that some companies refer to .3ds as the "3ds Max file format" but this is not true. The native file format of 3ds Max is the .max format, whereas .3ds is just a legacy import/export file format ported over to 3ds Max by Tom Hudson during the transition from 3D Studio R4 back in the early 1990s. DO NOT use the .3ds file format to convert to/from 3ds Max but rather use Okino's dedicated PolyTrans-for-3dsMax plug-in system for 3ds Max.
