Hello - a couple of things - some of your objects are open - that will not work here:

The cutters should extend right through

The vertical cutter can be all one surface - Join and then MergeAllCoplanarFaces

I have also had weird behavior from BooleanSpilt, which I’ll link here in case it’s related and/or helpful:

Boolean Split joining cutting object to cut object

I am seeing the same thing. I select an object to split: [Select object to split] then I pick a cutting object [Select cutting object] but Rhino chooses to conduct BooleanUnion instead [Discover the cutting and split object have been booleanUnioned] … and discover as a bonus that Rhino has also conducted a split but it hasn’t split the target object but the cutting object: [Screenshot 2024-01-28 at 2.30.03 PM] I am having to spend a lot of time making extra copies of things to replace o…
