algorithmic modeling for Rhino
Hi all,
I'm looking to apply a transformation to this shape by applying a twisting to it. I've been able to do so before by subdividing and rotating each slice. Is there a way to do this while maintaining the "logic" of the shape, i.e. so that when I apply a "DeBrep" component, the vertices and faces are able to be selected.
Thanks

UPDATE: I've managed to rotate each vertex depending on its height, I just need to remake the solid. Is there a quick way of doing this without manually rebuilding each surface? Maybe a remap surface thing?
Are your edges supposed to remain straight? Or should they be twisted too? It can be quite difficult and even impossible to exactly fit a nurbs surface through a set of edges that are not co-planar. This sort of approach would work for meshes, but for breps it is a lot harder. If you want all the points and all the edges and all the faces to twist at the same time, then you can use a SpaceMorph (like the Rhino twist command does), but that will deform everything.
Thanks for the reply David, I drew closed polylines, referenced back in Grasshopper and used FPatch to create the faces. I was wondering if there was a way to do this just through Grasshopper, possibly by treating each face separately, deforming, creating closed polylines from the points and then using FPatch?
