Surface - Square Grid Collision or Intersection

Hi,

I have a square grid and a planar surface in grasshopper. I was wondering if there was a way to capture each square of the grid that has some portion of it inside of the planar surface.

Thanks!

You can use isotrim component for this.

Hi,

Thank you for your reply, although i am a little confused still.

Imagine that grid you have shown here, but now there is a ‘blob’ of a surface on it. How would i capture the squares that share some area with the blob?

Thanks,
Tim

It’s probably not the most efficient way to do this, but it works. I’m just referencing a curve to form a surface, then projecting the grid onto it. Then dispatching the list based on the list length of the projections.
