Question: Wrap curves around loft (Grasshopper)


I am using Rhino 7, the latest version. I would like to wrap a number of curves (ellipsis) around a loft (cylinder) and I cannot find the best way to do that.

I tried “pull curve” and “project”, but none of these produce the desired results. Almost certainly there is an obvious (i.e. simple) solution, but I cannot seem to find it.

Will be grateful for any help.

Not the result you’re hoping for?

Is this what you’re trying to accomplish?

This uses the Unroll Polysurface component from the Pufferfish plug-in. (26.3 KB)

Hello Paco Paco,

Not exactly what I was expecting indeed. This is the trouble I had with “project”. Thank you nevertheless.

Hello Kevin,

Thank you, that is exactly what I was looking for. Thank you for taking the time!

I was hoping to accomplish this without another plugin, but so be it. I will give it a spin right now. I think I can get around the “unroll polysurface” component perhaps. Let’s see.
