How to convert DWF (DWFx) to Maya (.ma,.mb)?


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.

     

Maya

Maya is a well known and respected DCC/Animation system which had originally been developed by Alias Research in Canada then purchased by Autodesk in 2006 after Alias went bankrupt.

As is very little understood, no program on this planet can read or write Maya ".ma" (ASCII) or ".mb" (binary) files because the full geometry modifier stack of the Maya 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 well known PolyTrans-for-Maya system, which allows for all Okino 3D converters to run within Maya itself. For example, if you want to convert to/from CINEMA 4D (.c4d files) then you would do so entirely inside of Maya.

Due to multi-decades history, Maya users are notorious for using the OBJ file format to convert files to/from other software packages just as 3ds Max users wrongly use the 1985-era .3ds file format. OBJ is an "okay" file format but there are much better or more preferred methods to convert the data.
