Mesh Relaxation

Hi!

I'm trying to reverse engineer the San Gennaro North Gate designed by SOFTlab. At the moment, I created a surface with 2 extrusion and trimmed the surface in Rhino, turn out that I couldn't create a smooth mesh that allowing me to use Kangaroo to relax the mesh to get the surface like the North Gate. Would anyone know how to solve the problem? Or are there any other way to recreate surface like this structure?

Thanks a lot.

You need to start with a mesh, not a NURBS surface as they are not able to produce the right topology. If you are unfamiliar with the issue of topology for NURBS and mesh geometries I suggest a bit of previous research.

The usual workflow is:

. low-res mesh topology

. subdivide

. relax

Check the initial mesh in the attached example. In my case the naked edges are all sharp, but you can easily figure out how to smooth the ones you need in order to approximate a circle when performing the initial subdivision.

Hi!

Thanks for your quick reply! By starting with a mesh, do you draw mesh on rhino from scratch instead of turning NURBS surface/polygon into mesh? I think the part of creating the correct mesh is confusing me the most. How do you create the mesh you did in the grasshopper file?

Thank you very much.
