Hi, I have little exprience with GH and am trying to divide a collection of irregular surfaces with a similar grid, and have no idea how to do this. I tried using isotrim but it ignores the surface original shapes, and also thought of trimming them but that didn’t work as well.

Any help will be greatly appreciated![SRF-DIVIDE.gh|attachment]
