How would you achieve something like the below image in Rhino? [Screen Shot 2022-09-13 at 10.44.51 PM] I thought about the following, but there must be an easier way; tracing the edge pulling control points in Z direction to make 3D splitting curve into sections Sweep2Rail using segme…

My workflow for such shapes(I’ve designed dozens possibly hundreds of concepts for high-end playgorund equipment based on this general idea)is to make a 3D curve along the centerline of where I want the strip, then make a flat(to start with)plane for the ribbon and “Flow” that onto the curve with hi…

I can’t help feeling that people are underestimating the work that has gone into this shape to achieve the subtleties of the curves…

This is an interesting idea, thanks! How would you initially get the flat surface from the curve? ExtrudeCrv? I have tried this as a starting point and because it self-intersects it becomes difficult.

Nah, with Flow, History, and cage editing this is child’s play.

Just draw a simple Plane, make a center Line along its length, and Flow it along the 3D curve. Then, to make it twist around I can use the Twist command on the plane, or Cage editing, and to change the profile I might do cage editing or just point-editing.

You think I’m joking? The challenge is rationalizing such a concept into sections of pipe with a minimum number of bend radii. [fox-hill-3]

I’d shape this by hand with a strip of plastic / paper / foam, 3D scan it with my Artec Leo and then quad remesh…
