If you have any trouble installing or using the demos, email support@okino.com

WARNING: Do not install the demo version over top of a commercial, non-demo version.

A demo-limited version of the stand-alone PolyTrans and NuGraf software packages are available for immediate download. In addition, a secondary download of the "Okino Plug-Ins Super Installer" will allow you to install native Okino import/export converters directly into 3ds Max and Maya. The PolyTrans-for-CINEMA-4D conversion modules are included in the stand-alone Okino software.

Before rushing to download the software please read over and follow the 3-point procedure outlined in the "How to Properly Evaluate Okino Conversion Software" section first. That is the most critical aspect of the entire evaluation process.

Please do not use any of the free converters that come with 3ds Max, Maya, CINEMA-4D or LightWave as part of your end to end conversion pipeline but rather always use Okino's dedicated conversion methods. Also, as the #1 concept to follow to achieve perfect conversions, always source your CAD file data using the short "rule set" as outlined here which is applicable to all of our users.

How to Properly Evaluate Okino Conversion Software

Okino software is not something which you would normally download just to "kick the tires" and see if it can load in the CAD/DCC file which you may have been blindly given by a third party vendor. Okino software has been written over hundreds of man years of development and will achieve mathematically correct conversions for all source to destination paths, but it must be done with the correct choice of the source file format + converter combination (but notably the proper sourcing of your CAD data).
Many of our new customers come to us with well known misconceptions about how they should convert their data files and (in many cases) incorrectly sourced CAD files. Okino is an engineering R&D company for which we work closely and at a grass root's level with our user base, whereby education and awareness is a critical aspect of achieving perfect data translations. Hence, we will always exchange at least 2 or 3 short emails with every potential new user to ensure that they are approaching their conversion process in the correct manner, notably to explain the proper way to source their CAD files and also what conversion method should be used.
The following is the manner in which we interact with all of our new or long-term Okino customers, or anyone evaluating our software for the first time:

1 - As the most important step to take in our educational process, please send a short email to our CTO Robert Lansdale (lansd_support@okino.com) with the following information:

1a) - The name of the source 3D program and file format from which your data is coming from. Most people will say "IGES or STEP" but that is not entirely correct. It is the name of the source MCAD program which would be most important (SolidWorks, ProE/Creo, etc.) as that ideally defines which source file format should be used. If you are unsure then Robert Lansdale can explain how to discern that information very quickly from your data.
1b) - The destination 3D program and/or file format into which you wish to convert the data.
1c) - Many of our new customers have a "problem" they wish to overcome even if they are not aware of it. If there is some underlying issue which you are having then please state that in your email.

2 - There are some people who are not aware of how to properly evaluate software for CAD imports. It is not the export process (into your destination program) which is important whatsoever, since our Okino software has complete control over that process. Rather, the most important aspect of the conversion process is the import phase since that is where the sheer complexity of the conversion occurs. Thus, as we've explained to new users for 25 years, what you would want to do is to import your source data into our stand-alone PolyTrans or NuGraf program, then press the "Render" button (on the left-most vertical toolbar) to see the entire model with no demo limitations. Whatever you see in the scanline/ray-traced rendering is always what you will get when exported to any of the 3D file formats supported by Okino software. The export process, or conversion into 3ds Max, Maya, CINEMA-4D, LightWave, etc. never has to be 'tested' since the export process is under Okino's complete control and as such will always produce a proper file. Even with this stated paragraph, people will still write to us weekly asking "Why are there holes in the model once loaded into my destination program?" -- if there were no demo limitation holes then there would be no reason to pay for the software since it would then be fully functonal.
3 - Okino software is system-architected and direct-developer supported by Robert Lansdale (our CTO), who works "one on one" with each and every new or existing customer. We do not run a face-less company -- customer communication is front and central to everything we do each day. As such, if you would like a non-demo conversion done by us, or chat with us about the best choice of import/export converters and options to use, then please email us now. You should get a response back within a few minutes, or at most 4-6 hours, during our typical 16-18 hour work day, 7 days a week.

PolyTrans and NuGraf Combined Demo

A unified installer is available for downloading either NuGraf or PolyTrans. Press the "Download 64-bit (x64) Now" button to begin installation for Microsoft Windows.

Download the Combined NuGraf+PolyTrans Demo (195MB)

If you wish to execute the Okino import/export converters natively within the user interface of 3ds Maya or Maya then you must also download and execute the Okino "Plug-Ins Super Installer" described below. This is a major component of Okino software used by most 3ds Max and Maya users.

! Quick Notes !
1) This unified demo also includes all the components to perform the bi-directional CINEMA-4D conversions as explained in the "How it Works" section of this page.
2) The demo version has the optionally-purchased CAD/Pack, Granite/Pack and DCC/Pack modules enabled by default so that you can easily test them. For the commercial version you need to optionally purchase these add-on modules. Most configurations purchased by our customers will include one or more of the CAD/Pack, Granite/Pack and/or DCC/Pack modules (but almost all sales are for the Dual-CAD-Granite/Pack configuration).
Program requirements:

Microsoft Windows Ten/Eight/Seven 64-bit (x64).

You will need to have 'Admin' rights during installation (or, better yet, right click on the installer and choose 'Run as Administrator...'). You do not necessarily need 'Admin' rights to run the software.

There is just one runtime requirement: the Okino "vcplugin64" directory needs to have 'write access' when run in non-Admin mode (but only for a select subset of files, namely the *.xml, *.ini and *.dat files, as this directory acts as the central database to all the licensed CAD SDKs and toolkits). A warning dialog box will appear during program start-up if this is the case and that dialog box will explain how to change the R/W access on this Windows directory.

Preferably 16GB of memory. 32GB is more than ample for 99% of all CAD conversions.

For Mac OS X, any good Microsoft Windows emulator. A significant number of our customers have run on the Mac platform for well over 2 decades. 'Parallels' (especially in the 'Coherence mode') or 'VMWare' are both excellent methods of running Okino software natively on the Mac. Please note that PolyTrans-for-Maya requires a PC version of Maya.

Uninstallation Procedure:

From the Microsoft Windows START menu, choose the "Control Panel" menu option and then the "Programs and Features" applet. Thereafter select the listbox entry named "Okino NuGraf/PolyTrans Demo Installer" and click the "Uninstall" button.

The demo is limited in the following manner:

Exported 3D files, or files viewed in the stand-alone Okino PolyTrans/NuGraf software, will have every fifth polygon removed. As noted in the explanation above, please press the "Render" button on the vertical toolbar within the stand-alone NuGraf or PolyTrans software to see the model with no holes poked in them. Data imported into 3ds Max and Maya, via the native plug-in systems, will have these holes poked in the datasets as well, otherwise the software would be fully functional and there would be no need to pay for the software.

Okino native .bdf scenes cannot be saved to disk in the stand-alone software,

A small watermark bitmap will appear in the lower-left corner of all rendered images,

Texture files used for rendering or re-export will have black lines added to them,

Only the first 25% of object animation keyframes will be converted,

No camera animation data will be converted.

Optional CAD Importer Installers (JT Open, CATIA v4 + v5)

The combined PolyTrans & NuGraf demo version (see explanation in previous section) contains all the Okino CAD importers except for the following which must be installed separately, after the main demo software has been installed.
Please click on the "Download Now" button and execute the respective 64-bit CAD installer:

1] JT Open import and export CAD converters (40MB)
Refer to the "JT Open" WEB site for a gallery of JT files to import into Okino software.

2] Spatial CATIA v5 and CATIA v4 CAD importers (296MB)

Plug-Ins 'Super Installer' for 3ds Max and Maya

Currently Supported Plug-In Versions:

The demo versions are fully compliant with all 64-bit (x64) versions of 3ds Max and Maya.

3ds Max 2013 through to 2020.
Maya 2013 through to 2019.

!! Please Note !! These native plug-in modules require that the demo version of NuGraf or PolyTrans (stand-alone) be installed first (see above).

Download and run the Okino Plug-Ins 'Super Installer' for 3ds Max and Maya

To download the demo version of these plug-ins modules click on the "Download Now" button for 64-bit (x64) Microsoft Windows. Execute the downloaded installer to choose from the various versions of 3ds Max and Maya to install the connector plug-ins into.

A pivotal aspect of the Okino software for many of our users are the PolyTrans-for-3dsMax and PolyTrans-for-Maya native plug-in systems. These are two of the most professional, longest developed and well supported 3D converter plug-in systems for 3ds Max and Maya. These modules allow 3ds Max and Maya to directly import/export all of the Okino supported file formats from within their respective user interfaces. Other common uses of the plug-in systems is for bidirectional 3ds-max/Maya conversions (via the Okino .bdf file format), import & optimization of large CAD datasets from all major 3D CAD packages & file formats, import/export to all 3D gaming file formats (including skinned mesh and skeleton conversions), OpenFlight VisSim conversions, VR/AR conversions for Unity and Unreal Engine, and of course bidirectional conversions to most other 3D file formats and software packages.

Quick Usage Info for 3ds Max and Maya Plugins

During installation of the native 3ds Max and Maya plug-ins you will be presented with options to show the online 'help' file and installation 'info' documents about each of them. At the very least, keep the 'View Info File' check boxes enabled and then review the documents when they appear.
To summarize how to use these plug-in modules:

[3ds Max]

Go to the "Utility" panel section of 3ds Max (right side).
Find and enable the "PolyTrans I/O Converters" entry in the utility panel list of plug-in modules. Drag & drop that new item to a utility panel button.
Click on the "PolyTrans I/O Converters" button in the utility panel.
PolyTrans will now run completely embedded within 3ds Max.

[Maya]

Enable the 'ptio.mll' plug-in within the Maya plug-in manager (Window/Settings&Preferences/Plug-In Manager).
Optionally install an icon on the Maya command shelf (pt_icon.bmp).
Type 'pt' on the Maya MEL command line to start up PolyTrans.
PolyTrans will now run completely embedded within Maya.

Additional (Optional) Component Libraries to be Downloaded & Installed

[Autodesk Inventor CAD File Import] If you wish to import Autodesk Inventor CAD files, and you do not have a full copy of Autodesk Inventor installed on your computer, then you will need to download and install the 'Inventor Apprentice' runtime COM server system from the Autodesk WEB site. This is now available by downloading and installing the 'Inventor View' application from this permanent Autodesk link. As mentioned on our Autodesk Inventor page, an equally good method to source your files from Inventor is with the DWF-3D file format and the Okino DWF-3D importer.

Utilizing & Understanding the 'PolyTrans for CINEMA-4D Conversion System'

PolyTrans-for-CINEMA-4D is one of the most important and well used aspects of Okino software. Okino has been MAXON Computer's sole 3D conversion provider and developer since 1998. We provide error-free and completely robust CAD and DCC conversions into CINEMA-4D, as well as conversion of native CINEMA-4D files into all major down-stream non-CAD 3D programs. The conversions do not require a local copy of CINEMA-4D to be installed; hence, the .c4d conversions can also be done natively with other Okino-enabled programs such as 3ds Max, Maya, LightWave, Adobe Acrobat, NGRAIN and our third party OEM conversion solutions.
PolyTrans-for-CINEMA-4D comes installed as part of our standard, stand-alone software. You do not need to install any other components into other programs. In particular, please do not use the Okino/MAXON helper plug-in which came with older versions of the MAXON "Engineering Bundle" package as that is now obsolete.
A quick "How it Works" overview can be read on this page and/or by following the short 4-point process outlined in the 'Best Practices' section below.
More detailed information about using the PolyTrans-for-CINEMA-4D conversion system can be found online here:

Best Practices for Sourcing and Converting your CAD Files

From our experience very few of our new users are aware of the proper techniques to source their MCAD data and import it properly into their destination program. There is absolutely nothing more important to a proper CAD conversion other than to source the CAD data in a proper and exacting manner. The following bullet points cover 99% of the common usage scenarios of all Okino software users:

First, import the CAD file directly into the stand-alone PolyTrans or NuGraf program (including CINEMA-4D users). If you are using 3ds Max or Maya then import the CAD data directly using our PolyTrans-for-3dsMax or PolyTrans-for-Maya software. Do not use any of the free import converters which come with CINEMA-4D itself nor the Okino "Engineering Bundle" plug-in which has shipped with CINEMA-4D since 2004 as that is now obsolete.

The following explains the best possible methods to source your MCAD data:

For ProE/Creo, import the top-level .asm assembly file only (whose name you would always ask of your vendor who is supplying the data); do not import every single .asm and .prt file which is provided with that collection of files (as some people wrongly do). Alternatively you can import from a top-level Neutral .neu.asm assembly file, or a STEP AP214 file. Please do not accept or import old 1995-era IGES "Surfaced NURBS" files which are exported by ProE/Creo by its default IGES exporter (if you must get an IGES file, always ensure that it was exported as a "BREP Manifold Solids" formatted file -- this is crtitically important!!).

For SolidWorks, import either the native SolidWorks top-level .sldasm file or alternatively a "BREP Solids IGES" file which has been exported from SolidWorks. Both methods will provide equally flawless conversions. You do not need to have a local copy of SolidWorks installed on your computer. For the latter, ask your SolidWorks data vendor to edit their SolidWorks IGES export settings as follows (1) press the "Reset" button, (2) change the top combo box to "Manifold Solid (type 186)" and (3) disable the "Flatten assembly hierarchy" checkbox. Do not use a STEP AP214 file from SolidWorks as we've seen cases where STEP files create missing parts whereas IGES BREP Solids files do not.

For Autodesk Inventor, our personal preference (which is the most 'mentally soothing' and fires the fewest brain neurons) is to have your vendor export out a DWF-3D file from Inventor. Alternatively, if you have Autodesk Inventor or InventorView installed on your computer, import the native top-level .iam assembly file (whose name you would always ask of your vendor who is supplying the data).

For Solid Edge, import the top-level .asm assembly file or a STEP AP214 file. You do not need to have a local copy of Solid Edge installed on your computer. If using STEP, the "AP214" option must be chosen on the Solid Edge STEP exporter options panel.

For Siemens UG NX, conversions, they are always best done with a STEP AP214 file or alternatively a JT file. The STEP file will give you complete control over the tessellation quality on the Okino side of the conversion pipeline whereas the tessellation quality will be set on the Siemens UG NX side for JT files.

For CATIA, you can best use a "BREP Solids IGES" file without having to use our native CATIA v5 importer. Refer to the notes below about asking for a "BREP Manifold Solids" file.

For AutoCAD, Revit and Navisworks, always import from a DWF-3D file (you will want to center the scene at the origin and pre-scale the scene so that it is no larger than 10k units in width, prior to exporting the DWF-3D file from these Autodesk programs). You do not want to accept a DWG file, as everyone would naturally use. DWG is the second worst file format after STL whereas DWF-3D is one of the very best file formats for data translation.

For MicroStation, import from a native .dgn file or STEP AP214. Refer to the Okino DGN importer's online documentation for a good discussion about how to best deal with the complexities of the DGN file format.

For Rhino, import from a native .3dm file.

For lesser used MCAD programs, please refer to the Okino CAD Compatibility page.

Second, take a look at the imported model's extents. After import you can move the cursor around the 4 view windows in Okino software to get a sense of the size of the model (by watching the XYZ value change on the status bar), or by using the "Measure Distance" toolbar button to measure the width of the model. If the model is too small then re-import it with a larger scaling factor on the last panel of an Okino CAD importer (such as 10, 100 or 1000). If the model is too large then re-import it with a smaller scaling factor on the last panel of an Okino CAD importer (such as 0.1 or 0.01). Continue this process until you can have the model imported at a sane "size". This will give you ideal z-depth buffering in your desired destination program.

Third, re-export to whatever file format is appropriate for your destination program (such as .c4d for CINEMA-4D).

Fourth, load the final file into your desired destination program to start immediate rendering & animation.

Important mini-tutorial about sourcing your files from IGES file format: the #1 epidemic of a problem in the conversion world today is the usage of the IGES file format by people who wrongly source their files without knowing what they are doing. We explain this in every pre-sales email we've written for most of the last 25 years which relate to IGES file usage. It is important to understand how to ask for the proper version of IGES. As some background, there are 3 completely different versions of IGES: the obsolete 1980's "Bounded Surfaces", the obsolete 1990's "Surfaced NURBS" and the post-2000's "BREP Manifold Solids". The IGES file format is excellent in itself but the correct version must be used (also, IGES files are limited to 2GB or smaller). The problem is, all top-6 MCAD programs output the obsolete 1995-era version by default. This is what leads to all the perceptual problems one would often see on forums where people end up with imported geometry that has randomly oriented faces, flipped normals, shading anomalies and parts which are exploded into thousands of individual pieces -- this is all due to using the obsolete 1995-era "Surfaced NURBS" variation of IGES. Hence, you MUST NOT blindly accept whatever data is sent to you, as that just doesn't make any technical sense. The solution is rather simple and straightforward: when IGES files are to be used, ask your vendor to choose the export option for "BREP Manifold Solids", or use a STEP AP214 file. If you are not aware of whether your IGES file is of the old or new variation, there is a simple way to check: open the IGES file with a text editor and look at the 3 digit number at the start of every second directory line - if the numbers are 141, 142, 143 or 144 then you have been sent the 1995-era version of IGES, whereas if the numbers are 150-based or 180-based then you have the new-style and proper, modern "BREP Manifold Solids" variation of IGES.
If you are not sure from which MCAD program your IGES, STEP or Parasolid file came from, examine the first 20 lines of the file by typing it out or examining it with any text editor. In 90% of the cases the name of the MCAD program will be listed in the header. Statistically, it will most likely be one of "SOLIDWORKS", "Pro/Engineer" or "UNIGRAPHICS NX", while to a lesser degree "Solid Edge", "Autodesk Inventor" or "CATIA".

3D Import File Converters From Third Party Vendors

Okino has had one of the most extensively developed plug-in development systems and APIs. Okino's plug-in development program allows third party developers and vendors to create new importers and exporters, as well as system-level plug-ins to create such add-in components as renderers, modelers and search engines.

Okino has actively partnered with dozens of 3D software companies to integrate the PolyTrans 3D data conversion software and technology into each of their respective products. Special plug-ins and "connectors" are available commercially from these well known companies:

MAXON Computer. Please refer to Okino's PolyTrans-for-CINEMA-4D conversion system. This replaces the prior "Engineering Bundle" which most MAXON customers will be familiar with.

NGRAIN Corp. Their "3KO" exporter is included with each Okino software installation.

Visual Components. Their connector system allows Okino 3D CAD and DCC file formats to be converted into the Visual Components "3DCreate" software. Please contact Visual Components for licensing information.

Cadmatic. Their connector system allows Okino 3D CAD and DCC file formats to be natively and directly converted into the Cadmatic and Nupas-Cadmatic software packages. Please contact Cadmatic for licensing information. PDF product brochure available here.

EON Reality has had select PolyTrans components included in their software packages since 1997.

How to Un-Install the Windows-Based Demo Products

To un-install the demo version of NuGraf/PolyTrans, select the "Uninstall" item from the START menu for 'PolyTrans' or 'NuGraf', or do the same from the "Add/Remove" control panel applet.
To un-install the demo version of the Okino Plug-Ins Super Installer, select the "Uninstall" item from the START menu for 'Okino Plug-Ins Super Installer', or do the same from the "Add/Remove" control panel applet.
If you receive a -1612 error during un-installation of an existing Okino product then simply execute the following text on a DOS command line or via the "Run.." menu entry on the START button:

msiexec /uninstall {guid} REINSTALLMODE="" REINSTALL=""
You need to replace {guid} with one of the following strings:
Okino plug-Ins super installer, demo version {4DE79189-E5DD-49A0-914F-E40919AAB597} Combined NuGraf/PolyTrans demo installer {A21684A9-64C9-4714-AF1D-15D9C8CE5EBF}
If the command line execution reports an error, you will need to upgrade to Microsoft Windows MSI Installer v3 or newer. Go to http://www.microsoft.com and search for this file to download: WindowsInstaller-KB893803-x86.exe".
