Blending ugly srf in gh and rhino

Grasshopper
1

Hi there,

This topic does come up in other threads, but I wondered if there was anything anyone could suggest with blending these surfaces either as open breps or meshes in grasshopper, or manually in rhino.

I often come across this problem, and I understand it is the fact the surfaces are an ugly mismatch and I often find myself manually stitching surfaces together in rhino using blend srf or surface from 2 3 4 edge curves etc. Is there a quicker way?

I was trying to define the curves I wanted to join with the contour component, but no luck with that! All components are native, apart from one that is from parakeet.

many thanks

I was able to follow your process until here, at Sweep2, where you get some nice Surfaces that can even be merged into a single Brep:

could you please describe what you are trying to achieve with the next steps?

I see some Voronoi on Surface are generated, but I don’t get why you scale those and them turn into Meshes

Hi,

Well, the short answer is aesthetics :blush:…you are right, that is a closed brep right there. What I’m doing is generating repeated(ish) voronoi pattern (using a parakeet component) on each of those untrimmed surfaces, which is exactly where the problem is because it breaks that continuity. So I’ve spaced each of those surfaces out (to avoid any voronoi overlapping). I’ve then changed it to a mesh with the hope I could join it with a delunay triangulation, somehow but couldn’t make that work.

I’m hoping to find a way to put it back together somehow without me baking it and doing it manually in rhino.

Thanks very much for taking a look at this, it’s really appreciated
