Detect multiple surfaces inside 1 surface

[GH-KN]

Hi,

Question;

There are 2 lists

List A: represent walls
List B: represent openings

Question: I would like to ‘identify’ which openings are inside a wall surface.
The collision component does it álmost correct.
But unfortunately, when there are more openings inside 1 wall it only returns the ‘first’ opening.

Any suggestion how I can automatically ‘identify’ áll openings inside a wall surface?

Oh, hello again surface openings guy

ps looks like you are completing some kind of a grasshopper test, huh?

Ahh perfect, thanks!
What is the name of that component?
Haha just making my life easier by making holes using GH

Thanks again!

“Clash” is the name of the component.
You are welcome!

Ahh thanks.
I just had a look, but unfortunately I don’t have the ‘clash’ component.
Is it part of a plugin? (color of component looks also different).

Or do you have a suggestion how it could be done in another way using standard GH component?

thanks again!

Oh, that component was featured in rhino 7:)
