How to convert DWF (DWFx) 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.

DWF

Okino knows of the DWF file format very well as we have been involved with its evolution since the year 2000. A DWF file is nothing other than a renamed "ZIP" file which contains other internal assets such as a HOOPS HSF 3D model file and several XML files used to describe meta data and other aspects of the model. You can rename the .dwf file to .zip and then open it in any ZIP handling software.

The HSF file format was created by Ithaca Software in the mid 1980's as an efficient, light weight, compressed 3D visualization format. Thereafter it was adapted and adopted by Tech Soft 3D in the early 2000s for use by Autodesk as a "3D variation" of its prior 2D-vector-centric DWF file format (and hence how HSF became DWF). DWF/HSF is considered a "polygonal mesh" file format and not a NURBS/solids MCAD file format.

DWF attained acceptable traction after 2006 when Autodesk made it a primary conduit to export high quality 3D visualization data from its main CAD products such as AutoCAD, Navisworks, Revit and Inventor. Okino considers DWF as one of its most important non-MCAD file formats to bring in very large 3D models (such as massive oil & gas rigs, 3D plants and refineries) from these 4 aforementioned Autodesk products as well as from AVEVA PDMS software.

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.
