Hello !
I am trying to scale the openings of my surface depending on the incident radiation. In order to do that I need one smooth surface but I have a mesh. Therefore gh scales every box of the mesh separately.
Does anyone know how to turn a mesh (output of kangaroo) into a surface without a grid?

Thanks for your reply ! But I don´t really get what you did there. I want the surface to be smooth and not split into these squares that came from the mesh.
You are using various add-ons that I don’t have (I never work with any add-on anyway - except K2). But you start from a flat Polyline (Patch is not required) and then you get a flat Mesh and then … various mysterious things are MIA.
So … IF the goal is some sort of “vault” (with openings) … use accordingly K2 in order to relax it (this yields a “smooth” Mesh) and then do your offsets on the resulting Mesh Faces (quads or triangles). Obviously if all the above were code driven (i.e. Loop the relaxation [put the K2 job into some piece of code] until a suitable result is achieved) … that could be way easier.
Hello
as your mesh is quads only you can transform it to Subd then brep
Or in Rhino transform it to Polysurface using toNurbs command
One thing you could do is regenerate your trimmed surface, as untrimmed, flat, using SrfGrid (Surface from points), grabbing the same point count for the U & V of your first (flat) mesh - then use the vertices of this mesh to find coincident points on the surface, so you end up replacing said coincident points (with those on the kangaroo-transformed mesh), making your new untrimmed surface from the points:
Your result is an untrimmed surface as opposed to a polysurface - in case that matters.

Try ‘pull’ or ‘project’ to see which one you like:
Well … IMHO the whole approach is pointless (IF an AEC type of vault is the target). See attached for an entry level take - without the things that matter i.e. the LBS (W truss, seft supporting torsion free modules … or other) and a zillion other stuff related with some real-life envelope.
But then what isn’t? 
Right. 'Not sure if the OP specified anything beyond needing a ‘smooth’ surface. Nonetheless I agree no patch is needed and that a nice mesh can be generated from the starting flat polyline.
How would you go about it? Simply quad-meshing it or partitioning the polyline using edge extensions + subdividing?
A Ducati Panigale V4S - what else?
The general case (any collection of curves outlining a BrepFace - or many) is exposed in the above C#. If some more “equalized/normal/whatever” footprint is required (*) then … well … one should do the outer Crv/Poly via various “ortho” constrains (rather very easy via code). But - in a hurry - set the rot to 0 and use an ortho Poly (so to speak).
But … this approach is pointless: think the end result (case: a “rational” LBS via a classic W Truss). I mean a vault (a pathetic topology anyway) that has a “smooth” rnd outer skin while the footprint is heavily constrained … is a muted kind of thing … kinda a Harley Davidson (avoid riding any model).
Moral: a vault should be “chaotic” in every sense (Again: IF an AEC vault is the target) . But the bad news is that you can’t solve it in real-life without code (life sucks).
Both things = invaluable information.
Thanks Peter.
