Hi all, I got into a tricky corner where I don’t know how to close the surfaces as it is going in 3-direction. Ideally, they should all be tengental on all sides of the surfaces. [image] I tried patch, sweep2, blendsrf, networksrf and all don’t really work. Could anyone please point me in the …

my surface styling skills are a bit rusty, but that was an interesting piece to think about. this is how I would approach such a thing the old school way: topology check: by adapting this little detail you change the (nurbs) rules to your favor. also the second neighbouring polysurface with the…

Thank you very much Bobi! really great tips! Learn new commands already!

Thank you @dk2079 ! Very clear steps! The result is what I am looking for. I will go ahead and try this method now.

Many of your common surface boundaries are not tangent, and two curves and the surface in between are overly complex. Before attempting to surface that 6-sided region, I would simplify the model and make the neighbouring surfaces tangent. [Skärmbild 2026-05-17 14.52.57]

thank you Lagom, may I ask how do you check these degree? I think it is a very good tool !

Exactly the reason why I wrote my post above regarding the need for clean surfaces and following a few other good practices for achieving proper NURBS modeling. In my opinion, the Rhino users must be taught to avoid overly-complex surfaces consisting multiple spans. Milti-span surfaces are the numb…

In 2025, I had to start providing Rhino courses (not for jewellery, not for shoes, not for architecture, not for ship/boat hulls), so I first waded through 20 years of comments made on this forum by quality users who know what they’re talking about, and integrated what I know from Alias, Catia, etc.…

I read the tips written in your link and they seem like a better help topics than the official ones that come in Rhino. However, there are 4 essential tips that I will explain here and hopefully you can add them to your page, too. Avoid using weighted control points (default fillets with degree 2…

Now that you pointed it out, I noticed it too. But now that I know it, before, when I enabled the control points, I never really paid attention to it and, as a whole, all the control points looked round to me. Do you think it would be possible to customize them, for example by making the control po…
