Cutting through an extruded cube object?

Hi everybody,

I know this is probably asking a lot, but is there a way to cut through an extruded 3D/isometric cube object with something like a knife tool?  Cinema 4D has the ability to do that. I know that's an incredible stretch from this environment but was wondering if there's something similar that can cut off the corner of a cube or something that can create object seperation or segmentation. 

As always, thanks for reading. 🙂
