Hello: Lighting and Skylights

I am new to grasshopper and I am having a difficult time with my first project.Basically my project is about lighting and skylights and assigning different skylight sizes to buildings depending on their program. I have an arbitrary site and randomly assigned 4 different programs to each building. I have managed to extract each program type but I can not seem to figure out how to make a skylight and have a an opening on the roof. I have figured out how to select the roof of the building but do not know how to show that there is a skylight there. An opening has to be present on the roof but I do not know how to go about doing this. If someone could please help me with this problem I would appreciate.

THANK YOU!!! =)

yes, i think so.. the buildings are all rectilinear but it should not matter right?

Thank you for you help =)

do you know how you choose the size of the opening?

Hi, Do you know how I can assign this to another set of breps? becuase I have been trying to figure it out and I can not figure out which components needs to connect to the brep?

Hi Melissa,

Here is another way to create skylights, slighty different to Chris workflow but with the same result. You will find there are many to create the same output.

Can you post up what currently have so i can better understand what your doing as theres a few ways your task can be done

Thanks

Matt

Hi Melissa,

Thanks for posting up developments of your project, I had a little look at how to simplfy your work flow so i could be done on all buildings at once and came up with this. Its a bit more of a re-write than an slight edit of your code posted...sorry, though hopefully it will help. On your code you posted you can use Cull Pattern in place of Dispatch is you only want the true or the false. To switch between Tor F are culled on the Cull Pattern Component use Invert in the Boolean Menu.
