Replace mesh vertices with NGon

Hi all,

I’m working on a project at uni and trying to create a 3D Mesh Face. The mesh faced is based on specific points I’ve created in rhino(to create a specific shape for a structure). I’ve tried Delaunay between the points and it works well which is great! Only issue is that the face needs to have 2 components which are different shapes. I’ve tried to use delaunay to create a mesh face with both triangles and then a six-sided shape (which I thought was easiest with the triangles), but I am struggling to make it work, as I’m fairly new to grasshopper. I am wondering, which process should I follow to create this? Are there any helpful plug-ins that would help?

Many thanks!

Hi Hanna and welcome to the forum. Please post your files and pictures (if possible) of your problem

Thank you! Here is the image of kind of my thought process with it last week (not quite sure where I was/ where the thought process was going?)

And here is my basic Delaunay mesh grasshopper!

Honestly i am having troubles understanding the problem from your explanation

No worries, apologies for not explaining it clearly! I can re-try, but many apologies if my explanation again isn’t helpful.

My issue is that I am not sure how to create a mesh, from this delaunay mesh i have created (based on specific points I’ve chosen on rhino) that has 2 shapes involved/interacting on the surface of the mesh? I had thought that I could have triangles, directly from Delaunay, as one shape, and a six sided shape as the other shape, perhaps made by combining the edges of some triangles (hexagon-like). The goal is to create bascially a pattern/arrangement of 2 shapes over this delaunay I’ve created. However, I am finding is very difficult to create the grasshopper for this and am not sure if it’s possible?

Feel free to ask any more questions! Hopefully I’ve made it a bit clearer?

Thank you!!

I am so sorry, it didn’t work for me either. I am equally confused by the title of this topic. How about sharing some sketches of the ‘ideal’ result? :grin:

Cheers!

I am still not sure i get it, but i think you want to replace mesh vertice with ngon.

This is perfect, and yes, this is what I was going for! Thank you so much!

Changed topic title to Add NGons to delaunay mesh - @dfytz1 you’re the solver so edit to better verbiage if you deem it appropriate

They obviously did! Beautiful sketches!
