I am not sure exactly what it is you're showing here to be honest. You have provided no information or links. Is this a tool you made? Is it just you playing with booleans?
It's a good exercise to write your own boolean tools, particularly if you're doing all the math yourself. But just fyi, there are several scripts that do the same thing in Maya already ("SpeedCut" and "BoolS" both come to mind).
