Make cell from lines

[Jonghyuk_Park]

Hello. I’m a very beginner for grasshopper and I’m trying to make cells from lines that came out from grid structure component.

I’m following a tutorial using ‘square grid’ that has output of cell but I wanted to create grid on the specific surface.

Can anyone help me for this?

You can give it a try with Quad Panels + Simple Mesh

The mesh can also be created with the native Mesh Surface component

While @martinsiegrist is totally on point, other cases may require/are more easily solved using this native RhinoCommon method (i.e. which is not yet exposed in native Grasshopper components):

Turn "mesh" made of lines in an actual mesh

FWIW, the native Mesh.CreateFromLines method automatically adds ngons: [2025-05-25 16_43_12-Grasshopper - line to mesh v2_] line to mesh v2_AHD.gh (14.5 KB)

Edit: Just had a look at the file and think I’d use something like this:

I’m not sure if there’s a native version (e.g. there is Surface From Points for making surfaces), but I certainly use my meshGrid Python a whole lot at work. It would probably be useful with a fully native component.
