To download German, please visit www.xnurbs.de (i.e., FILOU Software GmbH – our German reseller)

To manually install XNurbs to a folder you specify, you can rename the downloaded file extension from .rhi to .zip, and unzip it to the folder you specify – then refer to “Enabling the XNurbs Plugin” in the manual.

By double clicking the rhi file, Rhino should automatically install and enable the plugin. After running the rhi file, you need go to the installation folder and open “XNurbsHelp.chm”, which provides the detailed instruction for using the plugin (Run Rhino, then Tools > Options > Plug-ins > XNurbs > details > File Name.). If you don’t know where Rhino installs the plugin, you can rename the downloaded file extension from .rhi to .zip, and unzip it to the folder you specify. Alternatively, you can get a copy of “XNurbsHelp.chm” here (without the videos). If “XNurbsHelp.chm” does not show properly, then right-click on the chm file and select properties. You will see an “Unblock” option. Click on it.


SolidWork add-in (V3 is officially available.)

SolidWorks 2017 64-bit SP4.1 or later (60 MB. It works for SolidWorks x64 2017 SP4.1 or later, 2018, 2019, 2020)

SolidWorks 2017 64-bit SP3.0 or earlier (60 MB. It works for SolidWorks x64 2011, 2012, 2013, 2014, 2015, 2016 and 2017)

(V3.01 is the latest version.)

Extra efforts have been made and, without the need of any update, xNURBS SolidWork add-in should work with future SolidWorks versions in the foreseeable future, e.g., SolidWorks 2020, … SolidWorks 2030 etc.

We strongly recommend that you use XNurbsSetupAfter2017SP40: For Solidworks versions prior to 2017 SP4.1, due to a SolidWorks API’s problem, under some cases (i.e., when there are some specific tiny gaps between boundary edges), XNurbs may not trim the final surface generated due to the gaps between boundary edges. Updating to SolidWorks 2017 SP4.1 or later (with the corresponding XNurbsSetupAfter2017SP40 version) may fix the problem.

Instructions for installing and enabling the XNurbs Add-in.

After downloading the package, unzip it.

For SolidWorks 2018, 2019 and 2020 double click “XNurbsXXXXXX.msi” to run the installation.

For other SolidWorks versions, since XNurbs V3.0 needs Microsoft VC++ 2015 or 2017 Redistributables, so please run “setup.exe”. For most users, “setup.exe” will install XNurbs addin without any problem. If “setup.exe” returns an error as shown in the following screenshot “Another version of …” , then just close it and running “XNurbsXXXXXX.msi” will successfully install XNurbs addin.

After you download and install XNurbs, you can find “XNurbsHelp.chm” under your XNurbs installation directory, which provides the detailed instruction for enabling and using the plugin. If “XNurbsHelp.chm” does not show properly, then right-click on the chm file and select properties. You will see an “Unblock” button. Click on it.
