Hi, I’m fairly new to grasshopper and can’t understand perfectly everything it can do. I’m working for a firm actually that asked me to design a perforated metal skin that is gonna be used as a sun protection for the facade. The aim is not to duplicate the pattern on all of it and try to randomize…

Something like this is what you want? [Canvas%20at%2001%3B35%3B14] 181015-HEXA_re.gh (11.3 KB)

Hi, First of all thanks for your answer ! This is really gonna help me ! I have 2 more question, Is it possible to choose randomly the remaining hexagon ? Is it possible to keep the skin perforated at 20% at all time ? Regards. Théo

Which is what you want? [Canvas%20at%2002%3B06%3B50] [Canvas%20at%2002%3B11%3B10] 181015-HEXA_reV2.gh (16.9 KB)

I just got back to the agency and it works wonders !!! Thank you very much for your help and your time, it’s exactly what I wanted !!! Have a wonderful day ! Théo

Hi again, I ran into another problem… Working on a big scale metal skin, i was wondering if it was possible to optimize the time it takes to generate the Hexa Grid. And if so, is it possible to apply the script on only certain areas ? Thanks in advance for your answer.

Usually, nurbs operation will be computationally expensive(in this case, boundary surface at the end) when you are dealing with a large amount of geometries. Try to use mesh instead if possible. Or divide your whole geo into smaller pieces and apply your desired definition respectively.

Ok I’ll try that, I don’t need the boundary surface at all. The skin is going to be laser cut so I kind of need only the line, the contour of the boundary Surface. Thanks again for your help !

Perfect, it works a lot better ! I’ll just need to limit the grid to the Metal Panel. Thanks !

Hi again… I just realised that I still have a major problem. Working on a big scale skin and having the perforation at 1cm of diameter, it takes a lot of hexagon to fill my whole facade. Maybe you have a solution to limit the system to only the metal panels I need. Or should I just work panel by pa…

And you can get the reverse pattern just by reversing B output ofSort List.
