Hello all, I’m new in this forum. I’m investigating if Rhino (+Grasshopper) is something I should buy. I have a new project that probably could benefit from it. But It needs a lot of fillet operations. And I heard from a Rhino user that this feature is not so good in Rhino/Grasshopper 8 and should…

[image] Cor Jansen: I would like to try the evaluation version. But that is version 8. Do I have access to the WIP version while using the evaluation version I believe you do. [image] Cor Jansen: Will I have access to version 9 when buying version 8 now? You would only have access to …

[image] Callum Sykes: You would only have access to 8. To get 9 you’d need to upgrade Will the upgrade price depend on the time to the new version? If I buy 8 now and version 9 comes out in a week or so, for which I have to pay the full upgrade price, I would file a bit misleaded. Or at leas…

[image] futureViking: Fillets in 8 are fine A friend of my was at the Rhino developer day (or something like that) and he was told that fillets are not very good in Rhino 8 and that there is a complete redesign of fillets in Rhino 9 to make it how it should be (according the developers). I h…

[image] Cor Jansen: I have very bad experience with fillets in other CAD packages. So I’m a bit cautious about this. Do let us know how it goes when you try it. I’d also be curious for you try 8 and 9 and let us know which you prefer and how to improve!

G1 arc fillets with FilletSrf work very well Rhino 8 when your surfaces are properly set up for filleting. See also this script by @jim that automates much of it. Always go from larger to smaller fillets. It’s the business.
