Yes and no. It will work, in that it will cut the segment where you place the cutter, but if you have made your segment walls only 1 plain, then the wall you cut will have no depth.
I don't want to sound off hand, but this is not really my problem. Optimising your segment walls by reducing them to one plain, is kind of a fiddle from the FPSC standard, and not something many people are doing, therefore I didn't really account for that in ButterCutter.
Aside from that, I would assume that if you are modelling your level as chunks, and importing them as segments, it would be much to your benefit to create the holes in your modelling program, as opposed to using BC.

I'm sorry that this page got overcrowded with childish piracy stuff, on the previous page I did ask customers to kindly give it a few days before sending receipts, or "where is it?" emails.
I'll have it off to you by the end of play tomorrow.
