Thank you for your reply Pierre,
Please find attached the file.
What also is the case with the converted Nurbs curvature analysis is that it is very heavy for my potent graphics card. Please find below my system info.
What I really would like is to set up a Zoom meeting and show you how I work as a professional in the marine industry with fine fairing ship hulls and how I use several analysis tools to create high quality fair shapes.

For now I guess the easiest workaround is to turn on the curvature graph in both U and V directions. Reducing the density will greatly improve display performance, and since patches made from SubD are quite smooth you will not loose much detail. Exploding the surface and working on small portions is another solution.
Thanks for the links, I’ve read this post and others on curvature analyis /graph improvements for SubD and NURBS and agree we need to improve them. I think we already have a lot of information to work with for now, but I’ll remember your offer to demonstrate to us how you would like to use them and connect with @GregArden (in charge of these tools, I just deal with providing the SubD part) to see if he needs more details.
Dear Pierre,
Thank you for your reply.
The main issue is that the scale for U and V are always different. So it is not useful to turn them both on.
And yes reducing the density helps a lot.
The reason that I like to have a Zoom session, is to brainstorm about new functionality regarding curvature graph. To show you how I use it today and my ideas to improve the overall functionality.
If @GregArden also likes that, I am happy to share my ideas.
Currently this is only kind of visible in ghosted display mode with a backface color option turned on. And only because ghosted + backface is badly implemented so all you see is backface color.
I am curious if this has been resolved. Also, I look forward to your excellent training. From your youtube video on SubD, it seems that SubD is very useful for hull design. It would be nice to know if fairing is possible.
Nope, afaik there’s no progress made in Rhino V8 WIP when it comes to analyzing the surface quality of SubD. Having that said, for 95% of the vessel hulls, Rhino Nurbs is the best way to model and fair vessel hulls. But for example, aft bulb arrangements of merchant vessels and twin skeg arrangements are much easier with SubD.
