Hello, I used control points in Grasshopper to create a flexible bow shape. This allows me to adjust the form dynamically. Later I plan to apply a conventional bow shape (sweep). Maybe without any splines !? Thanks 3Pt arc and sweep 03.04.2025.gh (35.8 KB)

You want the ‘Geometry’ output of Move (not flattened :bangbang:) instead of the ‘Transform’ output. Sweep makes no sense to me here. Actually, your code doesn’t appear to do anything you want :question: And I don’t know what that is :interrobang: [3Pt arc and sweep 03.04.2025]

Hi Joseph, It’s not a specific shape or “surface” . Maybe a kind of vase later?I want to create a concave or convex shape of the surface. But the surface should be flexible. Uploading: 3Pt arc and sweep 03.04.2025.gh…
