PolyTrans|CAD and PolyTrans|DCC for Windows
by 'Okino Computer Graphics'

PolyTrans is the leading industry standard for comprehensive visualization and data translation of all 3D CAD/CAM, VisSim and Digital Content Creation data. With its support of virtually every 2D and 3D file format you will need no other tool to visualize 3D models and translate them to your format of choice. With a user base of the entire 3D industry, and being in use constantly by 3D professionals like yourself, PolyTrans works 'out of the box' in the most complex and demanding of situations - it simply works!

Over the last 2 decades PolyTrans has pioneered and set the standards for scene conversion, animation transfer, skinned mesh & skeletons conversions, trimmed NURBS surface + curve conversion, crack-free and error-free CAD to DCC/animation package conversions, automatic bitmap conversion and many more innovative solutions. Okino is also well known for its personal, hands-on and fast technical support plus customer relations.

Important purchasing information: most customers purchase the base-level PolyTrans or NuGraf program and one or more optional add-on modules. Please be careful to review which modules you need before purchasing (add-on modules can be purchased at any time). The PolyTrans-for-Maya sub-product is configured as PolyTrans + DCC/Pack module. The native PolyTrans-for-3ds-Max plug-in system comes with each base-level copy of PolyTrans or NuGraf. Most Okino customers will purchase at least one of: CAD/Pack, DCC/Pack and/or Granite/Pack.

PolyTrans (and its elder brother NuGraf) are stand-alone programs which were written with one purpose in mind: to produce the most accurate, error free and robust conversions between all 3D DCC, VisSim and CAD file formats. PolyTrans was the first such program to market and hence has a long standing reputation of providing quality conversions as well as top notch technical support from its development team. The elder NuGraf program also provides for print quality photo-realistic rendering and more user interface controls for interactive scene composition.

 PolyTrans-for-3ds-Max, PolyTrans-for-Maya

These two special, native plug-in versions of PolyTrans run inside 3ds Max and Maya. For well over a decade they have provided the industry standard for add-on 3D CAD, DCC and VisSim converters inside of 3ds Max and Maya. This is one of the most popular aspects of PolyTrans in the D.C.C. community. PolyTrans-for-Maya is available via the "DCC/Pack" license. Note: Okino natively supports Lightwave (lws/lwo) and Softimage (dotXSI) file formats so no native plug-in modules are needed for those animation programs.

Popular uses include import of all CAD file formats into 3ds Max and Maya (SolidWorks, ProE native, STEP, IGES and dozens more), bidirectional conversion of complete scenes between 3ds Max and Maya, cross conversion of OpenFlight VizSim databases, cross conversion of DirectX files with skinning, excellent bidirectional Lightwave conversions, and many more long established problem-solving solutions for 3ds Max and Maya users.

 Customer Testimonials
  • "PolyTrans is a true 'workhorse' application. I've used it frequently on very large files and it has not choked, crashed, or needed to be reinstalled in three years, and this is on a Macintosh in VirtualPC. This software has become the indispensible hub of my daily work." Mark Banas, MAB3D.com

  • " We purchased PolyTrans and used it for 3D data conversion and optimization of datasets created for the NASA MER space program (Mars Exploration Rover Mission). It is fantastic software. My colleagues at another NASA center spent days using three software packages on what took me 15 minutes using PolyTrans alone (polygon reduction in batch mode worked like a charm). I just wanted to thank you for creating such a great tool." Boris Rabin, Visualization Development Lead, NASA/Ames Research Center, FutreFlight Central.

  • " I very rarely praise a piece of software but PolyTrans is nothing short of excellent and is the most used piece of software in our department. It is generally accepted within the modelling and graphics team that PolyTrans greatly improves our work flow and efficiency particularly with the seemless plugin to Maya and the accurate conversion from one format to another in either graphics or geometry. We would be lost without it." Lazaros Kastanis, immersive visualisation specialist, University of Queensland's Advanced Computational Modelling Centre.

 CAD Conversions and CAD Data Re-purposing Through PolyTrans

CAD conversion has always been a key aspect of Okino software development since 1988. One of our strengths is in converting all major CAD file formats to every non-CAD file format and animation package. Our converters simply work and work very well since they are in such widespread use.

 Highly Refined Conversions Between all Major Animation/DCC Packages
Okino Computer Graphics can best be understood as two distinct sub-companies: one which specializes in the CAD market, CAD products and CAD users, and one which specializes in the animation/DCC (Design-Content-Creation) markets and users. We excel at providing the industry standard converters for these distinct, yet often overlapping, markets. Okino is particularly well known in the DCC market for the last decade-and-a-half as the major provider of data conversion pipelines that tightly connects all major 3D animation packages and file formats. PolyTrans is in use by all major production companies who regularly use 3ds Max, Maya, Softimage, Lighwave, Cinema-4D, and related common file formats such as DirectX, Collada, FBX, OpenFlight, VRML/X3D and many others.
