Hi team, I have two polysurfaces, made of 3 (left) & 2 (right) breps, that I want to blend using C# script and the Brep.CreateBlendSurface (sourced from the forum). Effectively, I am trying to recreate the ‘chain edges’ command in Blendsrf on Rhino. My issue is that when I call the edge index, it …

Merge Breps Edited V0 RebuildBrepIntoSurface.gh (4.1 MB) This definition makes the Breps into surfaces. Note that BlendSurface in GH is not the same thing as Rhino’s. [image]

[image] Brandon Glasser: Maybe there’s a better solution that I’m not even considering! Hi, is this a unique operation? Don’t do such things in Grasshopper. There is absolutely no benefit in it, unless you are planing to repeat this process in a very similar way for more than 10 times. I thi…

Hi Tom, This is part of a very large GH script that aims to model a tailored shoe lasts from 3D scan data - hence the ‘unclean modelling’. The script is definitely intended for repeated use and hence the necessity to use GH and not model in Rhino

Thank you very much, I appreciate the script. I’ll give it a go, understand the operations and get back to you. Cheers Quan!

[image] Sweep2 rails: edge continuity and/ or Blendsrf component Grasshopper Developer Hi @Quan_Li , The Brep.CreateBlendSurface and the BlendSrf command are only similar in name only - the former does not use the same code as the latter, which is unfortunate. The goal is …

Scan or not, but this surface layout is problematic. You have too many cvs. And the iso curve flow is very bad, especially for blending. If you switch to a better surface layout, blending even with GH Blendsurface will yield a much better result. See my quick sketch: [sketch2] Other than that. Mo…

Thanks mate, I’ll be sure to reach out if we redo this area of the script :slight_smile:
