(I’m not a native English speaker, so I’m using a translation tool. I apologize for any mistranslations or awkward phrasing…) I’ve been using Grasshopper for over six years in my work, but I’ve always wondered why there’s no built-in method in Grasshopper to connect surfaces or Breps while maintain…

Hello, You can use Continuous Patch in Rhino9 WIP. [ContinuousPatch]

[image] Egret: I tried creating this component using Python and other languages in the past but gave up. I’d like to borrow your wisdom if there’s a better solution available now. Also, if there is a way to smoothly connect the gaps in the attached data, could you please let me know? You ma…

@11159 @jessesn Thank you for your reply! Actually, I tried that component last week, but there was almost no information available in Japanese, and I was stuck without knowing the correct way to use it. I’ll try again, thank you!

@11159 @jessesn Thank you for your continued support. I immediately tried out the Continuous Patch component. It worked well overall! However, there are areas where a complete G2 connection isn’t secured. Since it connects smoothly in some places, it doesn’t seem like a simple error. Could this…

Could you please attach the GH file?

[2026-03-02_16h21_36] 日本の方のようなので日本語で書くと、元の形状のアイソカーブの量が非常に多いように見受けられます。 [2026-03-02_16h29_20] 1/1000mmの精度でFitSrfコマンドを使用すると上記のようにアイソカーブが減ります。 [G0] またGconコマンドでエッジの連続性を見ると、G0で断面も連続していないようです。 [2026-03-02_16h32_33] ExtendSrfで面を延長し、連続した線を投影し切りなおすなども基本的な面を綺麗にするという意味で良いかと思います。 [2026-03-02_16h49_…

Masakiさん、日本語でのご対応感謝いたします。また、データ分析の方もありがとうございました。もしかしたらお察しかもしれませんが、アイソカーブがこれだけ多いのは、元の部品の表面の断面を一定間隔でつないでアントリムサーフェスを作成したことによる結果でした。 Brep上で式を構成するより1枚のサーフェスで作業した方が良いという感覚でしたが、おっしゃる通りこの形状の場合はまず精度を保ちつつ構成要素を簡略化するべきですね。そうすると製品面とアントリムサーフェスの誤差を確認しながら作業したいのですが、Rhinoのどのコマンドで形状同士の距離解析ができるのかわからず… 今まで、Rhino…
