Share xNURBS for ZW3D2023X

HI all:

XNurbs uses one simple UI to solve all kinds of issues for NURBS creations – It virtually has an unlimited capacity for solving NURBS and generating high-quality surfaces based on energy-minimization method. Its energy-minimization algorithm produces high-quality surfaces that are analogous to a physical model: when a wooden batten bends, it always assumes a shape that minimizes its bending energy to form a smooth curve.




This is wonderful tool to create high quality surface easily!

This looks interesting but I would like to read about it in English. The ZW Web article I can only find in Chinese. Is there a translation please?

Hi Liangfen,
fascinating stuff.

Can you please background how this came to be a plugin for ZW?
Who did that work?
And anything thing else you know about it that you can share?
Cheers - Paul

I found the answers at but I have mailed them to ask about the zw3d version of the plugin, because on the English site it’s only available for Fusion and Rhino. I’ll update you if they reply.

HI Cowboy99:

At present, it seems that only Chinese websites can download, the official plugin was mentioned as early as July, at that time, I did not expect that it is a third party, the plug-in English website can not be downloaded!
He is a multi-platform plug-in, SW and many other support!

HI Designs:
The plug-in is installed in English, and the site I provide has a ZW3D2023X download link!

OK. This was not obvious to me at first so I’ll explain the key facts I have discovered, for the benefit of English speaking users.

XNurbs is available as a plugin for ZW3D, which is on a 30 day free trial. After 30 days, a license fee is required to continue using it. The fee is discounted via the link, and it is approximately £115 GBP/$125.

It only runs with ZW3D 2023X, a service pack. This must be installed before xNurbs.

The plugin produces surface patches that are similar to FEM patches, but so far in my short trial, I have found them easier to get right, easier to edit and more data-efficient than FEM or N patches.

There are some useful tutorial videos at

If you use ZW3D for industrial design or other applications needing complex and accurate surfaces, this is definitely worth considering.
