How to cut off the plane

how to cut off the horizontal planes that cross the box?


you can do it this way…

it didn’t work for me :frowning:
I need the box to remove the horizontal planes that it intersects, and leave the rest

Well, you didnt describe the problem in clear manner.
Anyway the answer was already there. Just use other dispatch branch.

in fact, you need to make the “truth, untruth” Truth - there will be those planes that do not cross boxing. Not true - there will be those planes that will cross the box and move away

Uploading definition with internalized geometry allways helps.
