Regarding your post in the Boolean Split thread:

How can I divide a closed brep to one that contain many boxes in GH

@HS_Kim I saw your post on grasshopper3d on “splitting prep fails”. I love the boolean split component, thanks! Now I have a situation where it won’t work. Would you mind taking a look? [Bildschirm­foto 2023-03-09 um 12.15.23] I can’t get the second boolean split to work. [Bildschirm­foto 2023-03-09 um 12.19.35] First split. [Bildschirm­foto 2023-03-09 um 12.19.59] Second split. booleansplit.gh (207.8 KB)

I’m thinking along these lines but am not sure where you are going?

Split Brep Multiple failed until I gave it the unclosed brep, missing the last straight segment.
