PolyTrans|CAD+DCC Translation System - Overview


PolyTrans|CAD+DCC is the leading industry standard for comprehensive visualization and data translation of all 3D CAD/CAM, VR/AR 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 3 decades PolyTrans has pioneered and set the standards for crack-free and error-free CAD conversions, 3D scene conversion & size optimization, CAD model reduction & "instance-node" compression, trimmed-NURBS & BREP solids + curve conversion, bi-directional animation transfer, skinned mesh & skeletons conversions, automatic bitmap conversion and many more innovative solutions.

And above all else, Okino is well known for its personal, hands-on and fast technical support plus customer relations. We are one of the most knowledgeable and experienced companies in the 3D realm, for which our focus and interest is to bring proper understanding and awareness to all of our new + existing users.

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|CAD+DCC (and its elder brother NuGraf) are stand-alone programs which were written with one purpose in mind: to produce the most mathematically accurate, error free and robust conversions between all major 3D CAD, DCC, VR/AR and VisSim 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.

 Common Solutions & Benefits
  • The 'go to' tool for 80-98% reduction of CAD models for VR/AR in Unity, Unreal Engine, Microsoft HoloLens, Oculus Rift and under-powered tablet devices.
  • Converts entire scene files, including meshes with holes, trimmed NURBS, crack-free BREP solids CAD files, hierarchy, animation (format specific), pivot points, vertex normals, U/V tangent vectors, vertex colors, texture coordinates, textures, lights & cameras.
  • Converts & optimizes all major CAD formats to 3ds Max, Maya, CINEMA 4D, LightWave, Blender, OpenFlight and dozens more file formats and 3D programs (full list on WEB site).
  • No CAD model rebuilding necessary. Just import the CAD data as proper "BREP solids" geometry, convert & start your production work.
  • Cross-converts between all major animation packages and 3D file formats with true robustness & quality.
  • Publish to WEB streaming file formats such as DirectX, COLLADA, DWF-3D, HOOPS HSF, SketchUp (Google 3D Warehouse), U3D, XAML-3D & VRML1+2+X3D. Embed U3D in PDF files. Others in development at all times.
  • Highly refined & popular bidirectional 3ds Max <-> Maya pipeline via native plug-ins, with well over three decades of development.
  • The one and only professional 3D conversion program with native CINEMA-4D .c4d support (Okino has been MAXON's primary CAD conversion provider for over 3 decades).
  • Very popular solution for ProE/Creo, SolidWorks, STEP, etc. to DCC conversions -- they just work flawlessly.
  • Acts as a "stepping stone" to allow for massive CAD assemblies to be downsized in PolyTrans first before import into downstream D.C.C applications. This is one of Okino's core specialities, specifically for handling of super-massive oil & gas rigs, drilling platforms & 3D plants.
  • Import and compose 3D scenes from a plethora of 2D/3D file formats then render out to high quality images for print media, WEB presentations, training manuals, or marketing brochures.
  • 30+ year development. Personal and dedicated hands on support direct from the Okino developers.
  • Solid, robust solution used around the world by most major companies and professionals.
  • Easily develop new plug-in modules such as
    import/export, renderers, modelers, etc.
  • Mesh & scene processing toolset including robust polygon reduction system and "parts count optimizer" for top-heavy CAD assemblies.

 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 3 decades 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 CINEMA 4D (.c4d), LightWave (lws/lwo) and Softimage (XSI) (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/Creo 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.

 Optional Add-On Modules

 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 years, and this is on Mac OSX running Parallels This software has become the indispensible hub of my daily work." Mark Banas,

  • " 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 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.
