Hexagonal grid on surface- Closed berps to trim solid

Hi all,

I am new in this forum and hope someone can help me. I am trying to construct a small pavilion that can be divided into hexagonal panels to be later fabricated off hexagonal cardboard pieces.

I have been trying to make a definition with a hexagonal grid and offset edges so that I can apply this Grid to any surface I would like and then be able to analyze precisely the size of the hexagons.

The first direction I am taking is with a definition I already found. I am able to place this hexagonal mesh onto a any surface however, I need help with actually dividing this surface into those hexagonal panels so that we might cut and fabricate them. I would finally hope to divide the curved surface into straight panel boxes .

The other direction I am taking is attempting to make my own definition so that I can divide my surface into boxes and add hexagons with offset borders so that they might be able to be fabricated. In making this definition and am stuck on trimming my solids so that I will only have the geometry of the in between spaces. There is an error message that says all my surfaces need to have closed berps. How do I solve this? Where would the problem lie?

Please, I would appreciate any type of help tremendously.

Hi Gabriela,

No problem at all. I agree that simplifying things will make fabrication much simpler. As far as creating unrolled surfaces is concerned... are you required to do it in GH? Unfortunately, I am not familiar with the new lunchbox BREP unroller component, but it doesn't seem to work properly in this application. Can you just unroll in Rhino using the 'smash' command?

I usually use rhino to unroll surfaces because I have more control over how the geometry lies on the fabrication sheet; however, if you are required to use GH to unroll the surfaces, they are already planar so all that needs to be done is orienting them to a surface like in the digital toolbox tutorial I sent you.

I would definitely do it, but I am cramming for my end of studio review this Friday. After that I can help more, but I am sure many people on this site are experts of GH orientation.

When is your project due?

* n.m.: 'extrusions' are twisted here too...

Hi Gabriela, How did you trim the grid with your surface? I tried your definition but it applies it onto the square boundary of the curve I have and I want to limit it within the curve. How can I do it to achieve something like this photo
