Issues with splitting/trimming

So in the image, what I am trying to do is trim the bits of the cylinders off of the left side so I have this smooth effect on the left and the more orthogonal bits on the right. The issue is however that no matter what I do I cannot get it to trim or split. I’ve extended all the sides out so that the shape I want extends out of the shape I’m trying to trim and nothing. Somehow the only way it works is if I I move the cylinder even the slightest millimeter up or down, it will split, but it will not split in the exact location that I want it which is extremely annoying. Does anyone here have any suggestions? I’ll leave the file too if it helps.

Hello- I’m not sure I’m interpreting your note correctly, but is the attached something like what you need?

Yes! Thanks so much! Would you mind explaining how you did that? Was it simply extending that other perpendicular surface?

Hello - there needs to be a complete intersection between the cutter and the victim for Trim to work - I made a surface that extends all the way through your cylinders and not just part way through. Your surfaces had these curves of intersection with the cylinders (ghite):

Mine had these (green):
