Create a Mesh out of an irregular planar curve/surface

Hello all,

What I'm trying to achieve is to get the curve below on the right, made by Metaball Custom, to do the same "blown-up" effect as the shape on the left which was created in Kangaroo. I'm not sure how to get the curve into a mesh that will work. I have tried a few different ways but I always end up with a very messy 2D mesh that doesn't work when trying to adapt it to the GH script that created the 3D shape on the left.

Any and all help would be much appreciated... I was having a hard time searching the grasshopper site as well to help me out.

Thanks,

Jason

Hi,

this reply might be coming a bit late, but I have exactly the same problem, i.e generating a mesh from planar curves (in my case like a figure 8). I am trying to formfind gridshells.

I had to resort to generating the mesh inside a program known as formfinder (form finding tensile membrane structures).

I imported the boundary curve as a dxf and then used that to generate the mesh. I could control the resolution (lath spacing of 1x1 mt for example), and also change the rotational orientation of the mesh and then export different versions to rhino and gh.

Not an ideal situation but the mesh generated is very clean (no triangular faces at the periphery).

Although I think there is a way to do this inside GH. I will look at some legacy definitions i have and send them to you
