Grasshopper

algorithmic modeling for Rhino

Hi, 

Is it possible to convert a mesh into Surface by grasshopper 

as i know it is possible to convert mesh to polysurface in Rhino by command Mesh to Nurb

if it is not possible , how can i Populate or spread component into mesh or Polysurface

I don't think this method is suitable for your mesh.

Why not use Michael Pryor's method instead (a few posts up)?

It works fine.

Thank you for your reply. I need to panel the surface. I am still a beginner at this. I don´t know how to panel nurbs, that´s why I am trying so hard to get a surface from it.

Hi, read all this comment and could not find solution for my case. I have this floor that need to trasnfer to PLANAR SURFACES. Important is that I will keep them grouped into a number of surfaces so when I select room can get calculation grid and do not need to select many tiny pieces to get room shape.

Any help would be appreciated,

Michal

Your mesh has some problems, where the faces fold over others. You should clean up those.

Anyway, here's how you extract the naked edges. You can feed those into PlanarSrf to get one surface per room.

this is excactly what I was looking for ...thanks

Hi! could you explain me what to do after you input the mesh in the definition? how can i have the surface please?

y problem is that I made this surfaces in rhino, then I cropped parts of them and now when I try to use a formula of grasshopper in this cropped surface, grasshopper, somehow, reconstructs the whole original surface.

And my formula for truss making only works with surface parameter, noy brep nor mesh.

Do you know how can I solve this problem?

Thanks!

A few years have passed ...
I had the same problem to solve recently. The PATCH command gives a very distant from the original points to the new surface.
This is the way I used to go from points to Delaunay Mesh to a GridSurface:
