Varied Perforated Screen Help

Hi Everyone. I am quite new to using grasshopper so I was wondering if I could get some help!

I have trying to model a perfroated screen facade for a building but I am having a couple issues:

  • I want the pattern of the facade to have staggered circles perforations like the image I have attached. I tried to cull every second point to achieve this but I can’t quite seem to get it to work
  • I want the circles perforations to vary depending on the height. I have tried to do so by using the z value however the pattern doesn’t quite seem to be working and it seems to mostly at times vary within a panel rather than across the whole facade
  • I also cant quite manage to the the shapes of the panels to follow the curved cutout of the facade… (i want the panels on the edge to follow the curved edge of the overall shape)

Any help would be very much appreciated :slight_smile:

Have a look at this topic…

Don’t make DUPLICATE THREADS please! Be patient instead.


You probably need to flatten the input to Bounds so the range of Z values includes all the panels.

And yeah, please don’t create DUPLICATE THREADs.
