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.
