xNURBS Rhino Plugin V3

just wondering if anyone here has used this plug in ?

I have and I love having it as part of my toolbox. It depends on your modeling requirements how useful it is, but for my workflow, it has been a really great addition to my toolbox. I have the plug-in for both Rhino and SolidWorks.

Same here. We bought a few licenses and love it. If you do any complex modeling and do so commercially, buying this plugin is a no brainer.
